Dell UCS-51 manual Activating a Virtual Disk, Deleting a Virtual Disk

Activating a Virtual Disk

A virtual disk can become inactive if, for example, it is removed from one SAS 5/iR controller and moved to another one. The Activate Mirror option allows you to reactivate an inactive virtual disk that has been added to a system. This option is only available when the selected virtual disk is currently inactive.

1Select Activate Mirror.

2Press Y to proceed with the activation or press N to abandon it. After a pause, the virtual disk will become active.

NOTE: Activation of migrated virtual disks is only supported when the migrated virtual disk(s) is in an optimal state and contains all the physical disks.

Deleting a Virtual Disk

NOTICE: Before deleting a virtual disk, be sure to back up all data on the virtual disk that you want to keep. Follow these steps to delete a selected virtual disk:

1Select Delete Virtual Disk.

2Press Y to delete the virtual disk or press N to abandon the deletion.

3Press <F3> to confirm deletion of the virtual disk. After a pause, the firmware deletes the virtual disk.

NOTICE: If the physical disks of a virtual disk are removed and the virtual disk’s configuration is subsequently deleted from the SAS 5/iR controller, the physical disks show up only as simple disks with no RAID association if they are placed back onto the same SAS 5/iR controller. Once the virtual disk is removed from a SAS 5/iR controller using the BIOS Configuration Utility (regardless whether the physical disks members are present), the virtual disk cannot be restored.

Replacing and Rebuilding a Degraded Virtual Disk

In the event of a physical disk failure in an IM virtual disk, you will need to replace the disk and resynchronize the virtual disk. Synchronization will occur automatically on replacing the physical disk using the following steps.

1Replace the failed physical disk with a blank disk of the same type and capacity.

2Check your management application or the BIOS Configuration Utility (Ctrl-C) to ensure synchronization started automatically.

NOTE: The Dell SAS 5/iR controller only supports migration of consistent virtual disks and does not support hot migration of virtual disks.
