The View Enclosure window displays
the component and alarm characteristics of an enclosure that is selected
in the main window. For the SANnet II 200 SATA array, View Enclosure
also contains SATA MUX and SATA Router information. For SCSI, the enclosure is identified by the model name SANnet II 200L R or SANnet II 220L R. The ID is always 14 or 15. For SANnet II 110L R, the ID depends on the ID switch position. For Fibre Channel or SATA, the enclosure is identified by the model name, SANnet II 200F R or SANnet II 200B R. The ID is always the last ID within the enclosure in which the SES is contained. The model name is followed by an R or J. R indicates a RAID array unit, and a J indicates a JBOD. To view the enclosure, either double-click
the enclosure icon The upper two sections of the window identify the enclosure and provide related information. Note that when you have an array with multiple enclosures, you can use the Enclosure Number list box to reflect another enclosure attached to the same array controller. Alarm State applies only if you have an array with a SCSI Accessed Fault-Tolerant Enclosure (SAF-TE) (for a SCSI array) or SCSI Enclosure Services (SES) (for a Fibre Channel array) card.
NOTE: Controller events can also cause an audible alarm. Pushing the Reset button has no effect on audible alarms caused by a controller event. See Muting the Controller Beeper for information about muting the controller beeper. See Environmental State for information on power supply, fan, and temperature sensor locations. For the SANnet II 200 FC or SANnet II 200 SATA array, to display battery information, click Battery and see Battery Information. To display the FRU IDs and information for all FRUs in the array, click View FRU. The Environmental State section of the View Enclosure window reports the status of power supplies, fans, and temperature. For Fibre Channel and SATA, the status of the array's voltage is also displayed. It provides an overall environmental status of the chassis as well as the status of the individual components. The View Enclosure window specifies the SCSI Accessed Fault-Tolerant Enclosure (SAF-TE) firmware revision for SCSI arrays and the SCSI Enclosure Services (SES) firmware revision for FC and SATA arrays in the Firmware Rev field. Located on the I/O module, the SAF-TE and SES processors monitor environmental conditions. If one or more of the environmental components
is not working, but the array is still functional, the enclosure, array,
and server icons in the main window display a yellow (degraded) device
status symbol The Component/Status list reports the status of individual components, which might not always correspond to the overall status of the array. For example, if Power Supply #0 is pulled from the array, the yellow device symbol for degraded is displayed in the main window because the array is still functioning using Power Supply #1. SAF-TE and SES Temperature Sensor Locations
Monitoring temperature at different points within the array is one of the most important SAF-TE/SES functions. High temperatures can cause significant damage if they go unnoticed. There are a number of different sensors at key points in the enclosure. The following tables show the location of those sensors, which correspond to the Temperature # displayed in the View Enclosure Component/Status List. SANnet II 200 and 220 SCSI Array Temperature Sensor Locations
SANnet II 200 FC and SANnet II 200 SATA Array Temperature Sensor Locations
SES Voltage Sensors Voltage sensors make sure that the arrays voltage is within normal ranges. To check the status and determine the location of voltage sensors, refer to the SANnet II RAID Firmware Users Guide. NOTE: The Battery Information window does not apply to the SANnet II Blade SCSI JBOD array, the SANnet II 200 SCSI array, or the SANnet II 220 SCSI array. In the event of a power failure, the battery maintains power to the cache for 72 hours. When power is restored, the data in cache is dumped to disk. For the SANnet II 200 FC array, SANscape monitors the usable life of the battery and displays its status in the Battery Information window. The program calculates the battery expiration date using the battery type, manufacture date, and in-service date, which have been programmed at the factory. NOTE: For a battery FRU, you need to verify the in-service date so that SANscape can set it as explained in Verifying the In-Service Date When Replacing a Battery. The enclosure icon on the main window displays a degraded (yellow) status 21 days before the battery is going to expire. The enclosure icon also displays a warning (yellow) status if the in-service date has not been set for a battery FRU. A critical (red) status is displayed when a battery has expired. See Main SANscape Window for a description of device status symbols. To view the battery status, choose View > View Enclosure or double-click the enclosure. The View Enclosure window is displayed, showing the battery status in the Summary box. To view battery information, inclining type, status, manufacture date, in-service date, and expiration date, click Battery. The Battery Information window is displayed. NOTE: If the battery type is an early board module (FRU ID 370-5545 REVB), then battery expiration monitoring is not supported. Verifying the In-Service Date When Replacing a Battery
SANnet II 200 SATA Array For SANnet II 200 SATA arrays, the View Enclosure window contains SATA MUX and SATA Router information.SATA MUX and SATA Router Information To view the SATA multiplexer (MUX) board information for all SATA drives, select the SATA MUX Info tab. Each drive has on MUX board. The information for the MUX board includes the channel number and ID of the drive attached to the MUX board, MUX board serial number, MUX board type (active-passive or active-active), path controller (PC150) firmware revision number, and firmware boot revision. To view all accessible SATA routers behind the RAID controller, click the SATA Router tab. The information displayed includes the enclosure ID and enclosure serial number of the chassis that the SATA router resides in, the channel number that the router controls, slot position of the IOM board that the router resides on, router firmware revision number, router firmware boot revision, customer specified behavior (CSB) rev (a collection of memory resident parameters that define operational behavior of the router), hardware revision number, and the self-test revision number.
