Synchronizing a Virtual Disk
Synchronizing a virtual disk means that the firmware synchronizes the data on
the secondary disk(s) with the data on the primary disk of the mirror.
Follow these steps to start synchronization for a RAID 1 virtual disk:
1
Select Synchronize Mirror .
2 Press Y to start the synchronization or N to cancel it.
Activating a Virtual Disk
A virtual disk can become inactive if, for example, it is removed from one SAS
6/iR controller and moved to another one. The Activate 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.
NOTE: Do not migrate a volume or hotspares to a different system unless that
system does not currently have the maximum number of virtual disks and hotspares.
The maximum number of virtual disks is two and the maximum number of hotspares
is two. Exceeding this number may result in undesirable behavior.
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.
NOTE: If a virtual disk with defined hot spare drives is migrated to a SAS6/iR
controller that has a native virtual disk with defined hot spares already configured,
and the total number of hot spares is greater than the maximum supported number
of hot spares (2) then the migrated hot spare drive(s) will be deleted. After a reboot,
those drives are displayed as basic drives on the system. You can then create the
desired virtual disk and hot spare drive configuration using CTRL-C or the RAID
management application.
Migrating and Activating a Virtual Disk
Virtual disks and hot spares can be migrated from other SAS 6/IR controllers
only. Virtual disks cannot be migrated from any other controllers, including
the SAS 5 series of controllers or PERC series of controllers. During the
migration process, all systems must be powered down prior to removing and
