View Controller ConfigurationView Controller Configuration displays the components that comprise the array. To access View Controller Configuration, double-click the array
icon Controllers Tab
The Controller tab lists the controllers. To view more information about either of the controllers, double-click the desired controller or select the controller and click View. Depending on whether the controller is primary or secondary, the View Primary or View Secondary Controller Configuration window is displayed. Physical Drives Tab The Physical Drives tab lists the physical drives associated with the array. To see details about any of the physical drives listed, double-click the drive or select the drive and click View. The View Physical Drive window is displayed. Scan SCSI Drive For SCSI arrays, if a drive fails, the Scan SCSI Drive button is displayed. A SCSI hard drive can be scanned in and made available without having to shut down the array.
Identify Drive On To identify a single physical drive, for example, if you are receiving errors on a specific channel ID and you need to determine which drive is causing the errors, select the drive from the list, and click Identify Drive On. The selected drive's LED changes to amber and the button toggles to Identify Drive Off. Click Identify Drive Off to change the drive's LED back to green. Enclosure Info Tab The information in the Enclosure Tab includes the status of the power supplies, fans, and the enclosure temperature. To view more information about an enclosure in the list, double-click the enclosure or select the array and choose View > View Controller. Select the Enclosure Info tab. Select an enclosure and click View. The View Enclosure window for that enclosure is displayed. View FRU For SCSI arrays, to display field-replaceable
unit identification (FRU ID) information for the array, click View
FRU. Click View Controller Parameters to view detailed information on channels, RS 232, cache, disk array, drive I/F, host I/F, redundancy, peripheral devices, network parameters, and supported protocols. To view the information, click the tab that corresponds to the item you want to view. To change controller parameters, see Changing Controller Parameters. Channel Parameters Each controller has an RS-232 port and an Ethernet port. This architecture ensures continuous communication should one controller fail. Since the communication is established to only one controller at a time (even when the array is in redundant mode), the CurClk and CurWid parameters are displayed for the primary controller. Therefore, if a user maps one LUN to the primary controller and another LUN to a secondary controller, only the established connection to the primary controller is displayed through the serial and Ethernet port menu. As a result, if a primary ID is not mapped to a channel, and a secondary ID is mapped, Async is displayed in the CurClk field. |
