After updating array controller firmware or after connecting new drive enclosures to an existing controller enclosure, verify the firmware compatibility of all devices. If needed, obtain and install the supported controller or drive enclosure firmware. Firmware is available for download from the Customer Resource Center at the Cloud Systems Group support site.

Previous versions of the AssuredSAN 3000 Series firmware required an AssuredSAN 3000 series software plug-in in order to work with the VMware vStorage API for Array Integration (VAAI). This plug-in enabled the offloading of key ESX operations to 3000 Series storage systems.

Beginning with the TS251R004 firmware release, the AssuredSAN 3000 Series VAAI Plug-in is no longer supported. The AssuredSAN 3000 Series controller firmware now uses T10 compliance in an ESX Environment.

In order to properly upgrade your ESX Environment, perform the following actions:

1.      Determine whether your ESXi/ESX 5.x host has the AssuredSAN 3000 Series VAAI Plug-in installed.

2.      Disable the AssuredSAN 3000 Series VAAI Plug-in.

3.      Remove the VAAI vSphere Installation Bundle (VIB).

4.      Remove all claim-rules associated with the AssuredSAN 3000 Series VAAI Plug-in.

NOTE: Failure to correctly remove the AssuredSAN 3000 Series VAAI Plug-in and associated claim-rules will result in degraded performance and possible loss of access to datastores.

Important firmware notes

·         AssuredSAN 3000 series systems contain an embedded SMI-S provider for use by SMI-S client applications. The embedded provider is designed to support 3000 series configurations with up to 24 hard drives and up to 250 mapping paths. A mapping path is defined as a 3000 series volume presented through a 3000 series target port to a Host initiator.

·         In environments using replication, all AssuredSAN 3000 series controllers must have the same firmware version installed. Running different firmware versions among AssuredSAN 3000 series controllers might prevent replications from occurring.

·         To replicate between an AssuredSAN 3000 series system and an AssuredSAN 4004 series series system or AssuredSAN Ultra series system, the secondary volume must be exactly the same size as the primary volume. To ensure that the size is exactly the same when creating the secondary volume manually, use the CLI replicate volume command as described in the AssuredSAN 3000 Series CLI Reference Guide and the AssuredSAN 4004 Series CLI Reference Guide.

·         When changing a replication set (for example, adding or removing a replication volume, or deleting the replication set), do so from the source system; when aborting, suspending, or resuming a replication, do so from the destination system.

·         When changing the primary volume of a replication set, do so from the destination system first, then perform the change on the source system.

·         When using Windows Dynamic Disk (software RAID) on top of hardware RAID, there are some cautions to be considered. For more information, see the section “Real World: Dynamic versus Basic Disks” on the topic at

·         Failover and failback times are affected by the number of system volumes; the more volumes there are on the system, the more time is required for failover and failback to complete.

·         For AssuredSAN 3920 and 3930 hybrid FC/iSCSI controllers, mapping a volume via iSCSI and FC to the same server is not a supported configuration. Many operating systems' multipath solutions will not correctly handle the multi-protocols. Do not map a LUN in this manner.

Installation instructions

The following sections discuss installing firmware:

·         Installation notes and best practices

·         Installing firmware using RAIDar

·         Installing firmware using FTP

·         Installation troubleshooting

Installation notes and best practices


Do not cycle power or restart devices during a firmware update. If the update is interrupted or there is a power failure, the module could become inoperative. If this occurs, contact technical support. The module may need to be returned to the factory for reprogramming.


Before upgrading firmware, ensure that the system is stable and is not being reconfigured or changed in any way. If changes are in progress, monitor them and wait until they are completed before proceeding with the upgrade.


In dual-module enclosures, both controllers or both I/O modules must have the same firmware version installed. Running different firmware versions on installed modules may cause unexpected results.

Before installing this firmware:

·         Create a full backup of system data. (Strongly recommended.)

·         Schedule an appropriate time to install the firmware:

o    For single domain systems, I/O must be halted.

o    For dual domain systems, because the online firmware upgrade is performed while host I/Os are being processed, I/O load can impact the upgrade process. Select a period of low I/O activity to ensure the upgrade completes as quickly as possible and avoid disruptions to hosts and applications due to timeouts.

·         Allocate sufficient time for the update:

It takes approximately 45 minutes for the firmware to load and for the automatic restart to complete on the first controller module. When dual modules are installed, the full process time is approximately 90 minutes. If cascaded drive enclosures are also being updated, total process time may be as long as 180 minutes.

·         Set the Partner Firmware Update option so that, in dual-controller systems, both controllers are updated. When the Partner Firmware Update option is enabled, after the installation process completes and restarts the first controller, the system automatically installs the firmware and restarts the second controller. If Partner Firmware Update is disabled, after updating software on one controller, you must manually update the second controller.

During the installation process:

·         Monitor the system display to determine update status and see when the update is complete.

After the installation process is complete and all systems have automatically restarted:

·         Verify system status in the system's management utility and confirm that the new firmware version is listed as installed.

·         Review system event logs.

·         Updating array controller firmware may result in new event messages that are not described in earlier versions of documentation. For comprehensive event message documentation, see the most current version of the AssuredSAN 3000 Series Event Descriptions Reference Guide.

When reverting to a previous version of firmware, note the following:

·         Ensure that both Ethernet connections are accessible before downgrading the firmware.

·         When using a Binary firmware package, you must manually disable the Partner Firmware Update (PFU) and then downgrade the firmware on each controller separately (one after the other).

·         Reverting from TS250 or later to firmware prior to TS230 is not supported.

Installing firmware using RAIDar


Using RAIDar to install TS252 firmware is supported only when upgrading from TS230 or later firmware. When upgrading from all other firmware versions, install the TS252 firmware using FTP.

1.      Obtain the firmware package in .zip file format from the Customer Resource Center website at the Cloud Systems Group support site. Save it to a temporary directory, and extract the contents.

2.      Locate the extracted firmware file. The firmware filename is in the following format: TSxxxRyyy-zz.bin or TSxxxPyyy-zz.bin.

3.      In single-domain environments, stop all I/O to vdisks in the enclosure before starting the firmware update.

4.      Log in to RAIDar and, in the Configuration View panel, right-click the system and then select Tools > Update Firmware.

A table displays currently installed firmware versions.

5.      Click Browse and select the firmware file to install.

6.      Click Install Controller-Module Firmware File.

7.      Wait for the installation to complete. During installation, each updated module automatically restarts.

8.      In the RAIDar display, verify that the expected firmware version is installed on each module.

Installing firmware using FTP

1.      Obtain the firmware package in .zip file format from the Customer Resource Center website at Cloud Systems Group support site. Save it to a temporary directory, and extract the contents.

2.      Locate the extracted firmware file. The firmware file name is in the following format: TSxxxRyyy-zz.bin or TSxxxPyyy-zz.bin.

3.      Using RAIDar, prepare to use FTP:

a.       Determine the network-port IP addresses of the system controllers.

b.      Verify that the system FTP service is enabled.

c.       Verify that the user you will log in as has permission to use the FTP interface and has manage access rights.

4.      In single-domain environments, stop I/O to vdisks in the enclosure before starting the firmware update.

5.      Open a command prompt (Windows) or a terminal window (UNIX), and navigate to the directory containing the firmware file to load.

a.       Enter a command using the following syntax:

ftp <controller-network-address>. (For example: ftp

b.      Log in as an FTP user (user = ftp, password = !ftp).

c.       Enter a command using the following syntax:

put <firmware-file> flash

where <firmware-file> represents the binary firmware filename.

6.      Wait for the installation to complete. During installation, each updated module automatically restarts.

7.      If needed, repeat these steps to load the firmware on additional modules.

8.      Quit the FTP session.

9.      Verify that the expected firmware version is installed on each module.

·         Using RAIDar, right-click the system in the Configuration View panel, and then select Tools > Update Firmware.

·         In the CLI, execute the show version or the show enclosures command.

Installation troubleshooting

If you experience issues during the installation process, do the following:

1.      When viewing system version information in the RAIDar System Overview panel, if an hour has elapsed and the components do not show that they were updated to the new firmware version, refresh the browser. If version information is still incorrect, proceed to the next troubleshooting step.

2.      If version information does not show that the new firmware has been installed, even after refreshing the browser, restart all system controllers. For example, in the CLI, enter the restart mc both command. After the controllers have restarted, one of three things happens:

·         Updated system version information is displayed and the new firmware version shows that it was installed.

·         The Partner Firmware Update process automatically begins and installs the firmware on the second controller. When complete, the versions should be correct.

·         System version information is still incorrect. If system version information is still incorrect, proceed to the next troubleshooting step.

3.      Verify that all system controllers are operating properly. For example, in the CLI, enter the show disks command and read the display to confirm that the displayed information is correct.

·         If the show disks command fails to display the disks correctly, communications within the controller have failed. To reestablish communication, cycle power on the system and repeat the show disks command. (Do not restart the controllers; cycle power on the controller enclosure.)

·         If the show disks command from all controllers is successful, perform the firmware update process again.

Known issues and workarounds

The following is a cumulative list of known issues and workarounds:

Issue: CAPI hangs can occur in a linear replication environment.

Workaround: Increase the bandwidth between the primary and secondary systems.

Issue: Cannot use IPv6 addressing for controller network (management) ports.

Workaround: N/A.

Issue: Booting both controller modules with no seated disks can cause data loss.

Workaround: When booting controller modules with no seated disks, only run one controller module at a time.

Issue: Online help incorrectly indicated that spare drive scrub occurs every 24 hours instead of every 72 hours.

Workaround: N/A.

Issue: Live disk statistics IOPs do not match the ones displayed by Iometer.

Workaround: Use the host port or controller statistics IOPs.

Issue: FTP session disconnects or hangs on some occasions during firmware update.

Workaround: Enable auto negotiation on the management network ports.

Issue: Vdisk scrub may report errors incorrectly if it is started right after a power failure and there is still a lot of data in cache that needs to be written to the drives.

Workaround: Retry the vdisk scrub.

Issue: After firmware update to TS252, the e-mail notification for controller failure may not have part number (PN) and serial number (SN) information.

Workaround: Reboot both controllers in the system one after the other.

Issue: If drives that had been active members of a vdisk are added to a system, and that vdisk's name is the name of a vdisk currently present on the array, commands that use the vdisk name may fail. This prevents actions from affecting the wrong vdisk.

Workaround: Rename the vdisk, delete it, or use the vdisk serial number instead of its name in commands.

Issue: Vdisks created with the CLI whose name includes angle brackets cannot be used in RAIDar to create volumes, snapshots, snap-pools or to perform a volume copy.

Workaround: Rename the vdisk using the CLI.

Issue: Drives in the array head do not spin up after adding expansion unit.

Workaround: None, drives do not need to spin up in this instance.

Issue: In the Configuration > Services > SNMP Notification page and Wizards > Configuration Wizard, Notification step, clicking on the Submit or Next button without explicitly providing the community strings will replace the community strings with an actual sequence of asterisks.

Workaround: Explicitly supply the community strings.

Issue: The AssuredSAN 3000 System Setup Guide describes the Cache LED on the rear panel in a way that might be confusing or misleading.

Workaround: Clarification of Cache Status LED details:

If the LED is blinking evenly, a cache flush is in progress. When a controller module loses power and the write cache contains data that has not been written to disk, the super-capacitor pack provides backup power to flush (copy) data from the write cache to the CompactFlash memory. When the cache flush is complete, the LED is no longer blinking.

Issue: Replications stop after a few iterations.

Workaround: Restart the management controller.

Issue: Newly installed drives reported errors.

Workaround: Replace the drive.

Issue: Historical data for a drive is cleared when a controller crashes.

Workaround: None.

Issue: A warning about the coin battery was not displayed in the RAIDar events log.

Workaround: Reset the controller date and time to be current and restart the management controller.

Issue: RAIDar reports an error of "input too long" when trying to map a volume that is part of a replication image.

Workaround: Shorten the length of the Snapshot Name. Selecting defaults in RAIDar adds 4 characters to an image name if the replication occurs when the set is created. If replications are scheduled when the set is created, 4 characters are added as a prefix, and 6 characters are added for the unique snapshot name. In either case 5 characters are added for the exported snapshot name.

Issue: When updating drive firmware, a message is returned stating that the disk is unsupported.

Workaround: None. The message is incorrect.

Issue: When creating a volume in RAIDar, if the user changes the units from GB to MB but does not change the volume size, the volume will be created in GB not MB.

Workaround: Validate the volume size after creating a new volume. If the volume was created with the wrong units, delete and re-create the volume.

Issue: The controller may take longer than expected to respond to SSH and Telnet requests.

Workaround: Restart the management controller.

Issue: The SMI-S modify volume name shows up as non-supported in Windows Server Manager 2012.

Workaround: Modify the volume name using RAIDar or the CLI.

Issue: An error message may be displayed when restarting the controller, even when the controller restarted successfully.

Workaround: None

Issue: In the RAIDar Configuration > Remove User page, the User Name field is not enabled, even though the asterisk indicates it is required.

Workaround: Select the user from the list using the radio buttons. The User Name field will be automatically filled in.

Issue: RAIDar may incorrectly report the local link status of controller host ports.

Workaround: Use the CLI verify links command to verify the local link status.

Issue: During a firmware upgrade of the controller, events will be generated indicating a mismatch of the versions compared to the versions in the firmware bundle (Event 363, Severity Error). This is normal operation, as the checks are done during the management controller boot process. After firmware upgrade is complete on both controllers, verify the versions are correct, and a new informational event the firmware versions match those in the firmware bundle (Event 363, Severity Informational).

Workaround: None

Issue: Historical disk and vdisk performance data is not persistent across controller power events.

Workaround: None

Issue: Vdisk Data Transferred and Data Throughput numbers appear to be much higher when using the CLI historical show vdisk-statistics [vdisk] historical command, compared to CLI live output show vdisk-statistics command. This is caused by the way that the historical and live values are calculated.

·         Live values are calculated based on the vdisk as viewed from the controller cache perspective. In the live statistics, performance numbers are obtained by accounting for when data is written from cache to disk or read from disk to cache.

·         Historical data is obtained by using the summation of the disk statistics for the disks in the vdisk. The historical vdisk data shows transfers to and from the disks in the vdisk that include the overhead of any RAID transfers as well as any host activity.

Because I/Os from the RAID engine are included, numbers for the historical data appear higher than the numbers for the live data.

Issue: Saving historical disk performance statistics from RAIDar fails with an invalid time-range parameter.

Workaround: Change the start date/time of the time range. Make sure the start date/time is after the last reset and, for new systems, is after the system install time.

Issue: In environments using replication, if the controllers have different firmware versions installed, replications may be suspended.

Workaround: Ensure that all controllers in replicating systems have the same firmware version installed. When firmware on the controllers is the same version, suspended replications automatically resume.

Issue: When a previously used drive is inserted in the enclosure, it may retain information about vdisks, volumes and volume mappings from its previous use. However, the LUN numbers of these volume mappings may conflict with LUN numbers currently in use in volume mappings on the system. If this occurs, the system resolves those conflicts by removing the mappings.

Workaround: Remap the volumes as desired.

Issue: In RAIDar, while trying to modify a vdisk name, / is replaced by a space.

Workaround: None

Issue: In the CLI, the create volume-set command using the same basename parameter for more than 999 volumes generates an error.

Workaround: Do not exceed 999 when assigning the volume identifier number.

Issue: In the CLI, the show sensor-status command does not show warning levels or indicate fan status.

Workaround: None

Issue: When a vdisk becomes critical, the array may generate multiple events.

Workaround: None

Issue: In event messages, power supplies are referred to by different terminology. Sometimes power supply 0 is reported as ”left” and sometimes reported as “0”. Likewise, power supply 1 is sometimes reported as “right” and sometimes reported as “1”.

Workaround: None

Issue: A serial number was not generated for SMART drive event 55.

Workaround: Identify the drive using the enclosure and slot number.

Issue: When using the CLI show master-volumes command, a volume that has been converted to a standard volume is still included in the display.

Workaround: Log out and then log back in to the CLI.

Issue: In RAIDar, global spares have a status of Up even if they are spun down using the drive spin down feature.

Workaround: None

Issue: In the CLI, the set prompt command allows you to enter more than 16 characters.

Workaround: None

Issue: In RAIDar, when logging in using an unsupported browser, the returned display does not show the correct list of which browsers are supported.

Workaround: Use only the following supported browsers:

·         Microsoft Windows Internet Explorer 7, 8, or 9

·         Mozilla Firefox 7

Issue: On the Configuration > Advanced Settings > System Utilities page, changing the Vdisk Scrub and Managed Logs settings at the same time may result in an error.

Workaround: Make these changes one at a time.

Issue: Manually creating a replication-prepared (secondary) volume and associating it with a primary volume originally created with pre-TS230 firmware can fail. Automatically created secondary volumes do not have this problem.


·         In RAIDar, use the Replication Setup Wizard or the Replicate Volume task or, in the CLI, use the create replication set command to automatically create the secondary volume. (Preferred workaround)

·         Issue the following commands in the CLI to specify the block size of the manually created secondary volume, ensuring that it is exactly the same size as the source volume (Alternative workaround):

1.      In CLI API format, use the show volumes <volume-name> command to determine the size of the pre-T230 volume in blocks. This is displayed by the "size-numeric" property.

2.      Use the create volume command and specify the size in blocks (obtained in Step 1) to create the replication-prepared volume.

3.      Create a replication set that associates the two volumes.

Issue: When using both the primary and secondary paths on both ports of the Qlogic iSCSI HBAs, failover does not work correctly on cable pulls.

Workaround: When setting up the Qlogic iSCSI HBAs, set up only the primary path for both ports.

Issue: When creating a volume set with the volumes mapped to LUNs, if there is a LUN conflict, the array stops mapping volumes to LUNs, but creates the volumes as requested.

Workaround: Ensure that there are no LUN conflicts before creating the volume set with mapping or map the remaining volumes to LUNs after the conflict.

Issue: For Fibre Channel systems connected directly to the server, the QLogic 8 Gb FC driver version on Microsoft Windows Server 2008 R2 x64 does not see LUNs when the array is set up for point to point.

Workaround: Upgrade to the latest driver version available or change the array host ports to loop mode.

Issue: For SAS systems, failover is slow when more then 128 LUNs are accessed from a Red Hat Enterprise Linux 4.x or SuSE Linux Enterprise Server 10 SP3 client.

Workaround: Map less than 128 LUNs to SAS clients.

Issue: In RAIDar, the Japanese version of some pages and some error messages displays English text.

Workaround: None.

Issue: The array incorrectly accepts a DNS name for the address of the NTP server in the Storage Management Utility. The array does not use DNS, and translates the name into an invalid “” IP address.

Workaround: Instead of a network name, enter the NTP server IP address.

Issue: In the Command Line Interface, the array incorrectly accepts a DNS name for the address for the SMNP, SMTP, and NTP servers. The array does not use DNS, and cannot connect to the server correctly.

Workaround: Instead of network names, enter the IP addresses for the servers.

Issue: In Windows configurations, the IQN shown by the NC551 card during POST may not match the IQN seen in the array controller. This occurs when the NC551 was set up in a boot-from-storage configuration. After an operating system is installed, the POST message shows the IQN that is supplied by the iSCSI Software Initiator, but the NC551 BIOS continues to use the IQN setup to boot the OS.

Workaround: Using the NC551 BIOS Utility, remove the boot settings and then log back into the array with the new IQN. If the volume used for mapping was explicitly mapped to the host, recreate the mapping for the new IQN.

Issue: When accessing more than 128 LUNs using a Qlogic iSCSI HBA in boot-from-storage configurations, the system may hang when a reset is issued on the array.

Workaround: Access 128 LUNs or less via the Qlogic iSCSI HBA when using the card in boot-from-storage configurations.

Issue: RHEL 4.8 may not discover all multipath devices and partitions during boot or reboot.

Workaround: This issue is addressed by applying the updated device-mapper-multipath package described in RedHat Bug Fix Advisory RHBA-2009:1524-1, available at

Issue: Under rare circumstances, some events from one controller are not seen on the other controller.

Workaround: Review the events from both controllers.

Issue: During a firmware upgrade, the firmware bundle version may show incorrectly.

Workaround: Wait until the firmware upgrade process is complete before checking the firmware bundle version.

Issue: JavaScript issues are seen when using Microsoft Internet Explorer in multi-byte language locales, resulting in truncated messaging and hung pop-up windows. These issues will be resolved in a future firmware release.

Workaround: This is a display problem only. When a pop-up window remains on screen with no update for a prolonged period, close and then re-open the browser. The Internet Explorer English locale and the Firefox browser do exhibit the issues.

Issue: In SLES 11 environments, when using the iSCSI initiator tools included in SLES 11, the host occasionally does not correctly log into the iSCSI array on reboot, even when set to automatically connect.

Workaround: Restart the iSCSI service on the SLES 11 host. This can be done by entering the following command: /etc/init.d/open-iscsi restart

Issue: SLES 11 may require multiple minutes (15+/-) to create all multipath devices during boot. This typically involves a system with a large number of LUNs and multiple LUN paths.

Workaround: None. Wait for the system to complete LUN and path discovery.

Issue: SLES 11 SP1 may not create all devices during boot. This typically involves a system with a large number of LUNs, multiple LUN paths, and the SLES 11 SP1 open-iscsi utilities.

Workaround: Do one of the following:

·         Install the following Novell patches:

o    kpartx-0.4.8-40.23.1.x86_64.rpm

o    libvolume_id1-128-13.11.4.x86_64.rpm

o    multipath-tools-0.4.8-40.23.1.x86_64.rpm

o    open-iscsi-2.0.871-0.22.1.x86_64.rpm

o    udev-128-13.11.4.x86_64.rpm

·         Run the /sbin/multipath -v 0 command to force multipathd to rescan all LUNs and paths and create any devices that were not correctly created before.

Issue: In rare conditions, the array controller may report that a supported 10 GbE SFP+, 10GbE Copper Cable, or 10GbE Direct Attach Cable is unsupported. This condition is most likely to occur when a SFP+, Copper Cable, or Direct Attach Cable is hot plugged into the controller while the controller is running. When this occurs, the following Warning message is recorded in the event logs: “An unsupported cable or SFP was inserted." At the same time, the host port does not show a status of "Down."

Workaround: Do the following:

1.      Verify that the SFP+, Copper Cable, or Direct Attach Cable is a supported component.

2.      If the component is a supported model, remove and reinsert the SFP+, Copper Cable, or Direct Attach cable.

3.      If this does not correct the issue with the SFP+, Copper Cable, or Direct Attach Cable connected to the controller, either remove and reinsert the controller or power down and reapply power to the array.

Issue: RHEL 5 Update 5 does not shutdown properly when using the iSCSI initiator utilities shipped in RHEL 5 Update 5 to access the array.

Workaround: See issue 583218 on the Red Hat Bugzilla bug-tracking system for the current status of the issue and possible workarounds.

Issue: When using explicit LUN mapping, using long IQN names for the iSCSI Initiator can cause the array to map the LUN incorrectly. A predefined area is used to store explicit LUN mapping information per LUN and, with longer IQN names, this area can be exhausted. This issue is not dependent on the number of paths to the LUN.

Workaround: Shorten the IQN name on the nodes.

The following formula is used to calculate the maximum IQN name length based on the number of hosts being explicitly mapped to a LUN on the array:


Maximum IQN Character Length = (4083 / n) – 7 (Where n = number of hosts nodes explicitly mapped to a LUN on the array.)


NOTE: By specification, 223 is the maximum IQN length allowed.

The following table provides the calculated values based on the number of hosts being explicitly mapped to a LUN on the array:

Number of hosts explicitly mapped to a LUN and the maximum IQN character length


Number of hosts explicitly mapped to a LUN and the maximum IQN character length


Number of hosts explicitly mapped to a LUN and the maximum IQN character length


















































































































Issue: USB CLI becomes unusable after a Management Controller reboot in Windows environments.


1.      Close down the terminal application. (Example: HyperTerminal)

2.      Open Device Manager and disable the “Disk Array USB Port” under Ports (COM & LPT).

3.      Re-enable the “Disk Array USB Port.” If the problem persists, reboot the host.

Issue: There is no indication that a LUN has failed over to the other controller.

Workaround: Using RAIDar, open up system events and scan for failover events. When using the CLI, use the show events command.

Issue: A replication is initiated, but only a snapshot on the primary volume occurs, or the replication is queued.

Workaround: Ensure that all systems involved have valid replication licenses installed and that all volumes and vdisks involved in the replication have started, are attached, and are in good health, including vdisks that contain the snap pools for the volumes involved. A replication normally queues when a previous replication involving the same volumes is active.

Issue: A replication set was deleted, but is later shown with the primary volume status of “Offline” and the status-reason is record-missing.

Workaround: This generally occurs when the secondary volume is detached and its vdisk stopped when the replication set was deleted, and then the vdisk of the secondary volume restarted. To correct this issue, reattach the secondary volume, set it as the primary volume, and delete the replication set.

Issue: An error message indicating “controller busy” occurs while creating a replication set.

Workaround: Creating a replication set immediately following another replication set creation may result in "Controller Busy." This is expected behavior. Wait and try the operation again at a later time.

Issue: In RAIDar, the Vdisk > Provisioning > Create Multiple Snapshots task allows a secondary volume to be selected, but fails the operation.

Workaround: User initiated snapshots are not allowed on secondary volumes. Do not select a secondary volume.

Issue: A scheduled replication is missing or replications are queued, but do not complete.

Workaround: A best practice is to schedule no more than four volumes to start replicating at the same time and for those replications to recur no less than 30 minutes apart. If you schedule more replications to start at the same time or schedule replications to start more frequently, some scheduled replications may not have time to complete.

Issue: Unable to perform a local replication (a replication where the external view volume and the destination volume reside on the same system) with a single vdisk.

Workaround: Create a second vdisk for the destination volume.

Issue: Deleting the replication-set from the destination system fails.

Workaround: Delete the replication set from the source system (the system where the external view volume resides.)

Issue: A replication set is missing the primary volume and the replication set cannot be deleted.

Workaround: Set the primary volume to the remaining volume in the set. You should then be able to delete the replication set.

Issue: On rare occasions, deleting a vdisk when volumes are in the process of rolling back may cause communications issues between the management controller and the storage controller.

Workaround: Cycle power on the array to resolve the issue. To avoid this situation, allow the rollbacks to complete or delete the volumes before deleting the vdisk.

Issue: Scheduled tasks are not occurring, and there is no indication of a problem in the schedules or the tasks.

Workaround: Restart both management controllers (MCs) of the array(s) involved in the tasks.

Issue: Cannot schedule volume copy operations, or scheduled volume copy operations for snapshots and standard volumes do not occur.

Workaround: Perform the volume copy manually. Scheduled volume copies of master volumes should complete successfully if the schedule permits completion of the volume copy before the next occurrence.

Issue: Debug logs are incomplete.

Workaround: Determine if the logs are incomplete by unzipping the log file retrieved from the array and examining the last line of the store_YYYY_MM_DD__HH_MM_SS.logs file for the lines: End of Data ]]></LOG_CONTENT></RESPONSE>. If the file contains these two lines at the end of the file, it is complete and you can forward it to your service support organization for analysis. If the file does not contain these two lines at the end, it is incomplete and may not be useful. In this case, repeat the log collection process after a 5 minute delay. Should the second collection contain the above specified lines at the end of the file, send it to your service support organization for analysis along with the first set of logs. However, if the second file does not contain the above specified lines at the end of the file, reboot the system and try once more to collect the logs. Be sure to send all collected logs back to your service support organization with a brief note explaining the actions you took and the result.

Issue: In a dual controller system, log in to one of the controllers fails, but log in to the other controller succeeds.

Workaround: Log in to the other controller and restart the inaccessible management controller using the CLI restart mc command or RAIDar Tools > Shut Down or Restart Controller page.

Issue: IOPs and Bytes per second may be lower or higher than expected for the workload.

Workaround: This is a reporting issue and not a performance issue. The correct values can be calculated by using the change in the Number of Reads and Number of Writes over time to determine IOPs, and the change in Data Read and Data Written over time to determine Bytes per second.

Issue: The array controller may interpret a switch login as an HBA login and erroneously present the switch port as a discovered host. This does not affect storage functionality.

Workaround: Either identify the erroneous host and do not attempt to use, or Disable Device Scan on switch ports connected to the array controller and restart the array controller.

Issue: During firmware upgrade, FTP is aborted from a Windows client after starting the upgrade.

Workaround: This is a client side FTP application issue. If this issue persists try updating from RAIDar, use another client, or use another FTP application.

Issue: Upgrading firmware failed with the error, “Unwritable cache data present.”

Workaround: The controller is not in a state that can reliably perform an upgrade without losing data currently in cache. Resolve the unwritable cache issue and retry the upgrade.

Issue: While updating the array firmware using RAIDar, if the array must reboot the management controller the web page may not automatically log the user out completely resulting in a blank page.

Workaround: Refresh the browser window; if the login page is not displayed, close the browser and restart it to access the login page and complete the firmware update.

Issue: While performing a firmware update using RAIDar to multiple arrays, the window showing the status of the upgrade may appear as a blank window.

Workaround: Updating multiple arrays at the same time can cause this issue. Perform one firmware update from one client at a time. Updating one array at a time from a client allows the window to refresh more accurately.
