SAS 5/iR BIOS
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.
1 Select Activate Mirror .
2 Press 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:
1 Select Delete Virtual Disk .
2 Press Y to delete the virtual disk or press N to abandon the deletion.
3 Press <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.
1 Replace the failed physical disk with a blank disk of the same type and capacity.
2 Check 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.
