Reconfiguring Or Migrating Virtual Disks
Does my controller support this feature? See Supported Features.
Reconfiguring or migrating a virtual disk enables you to increase the capacity or change the RAID level of the virtual disk.
NOTE: On software RAID S110 and S130 controllers, if a physical disk (SATA SSD or HDD) is removed from a virtual disk
and the same physical disk is reinserted (hot plug) into the virtual disk instantly, within a fraction of a second, then the
virtual disk state is displayed as Ready and the physical disk state is displayed as Online. However, if the same physical disk
is reinserted after a short delay, then the virtual disk state is displayed as Degraded and the physical disk state is displayed
as Ready.
To reconfigure a virtual disk:
1. Review the information in Starting and Target RAID Levels for Virtual Disk Reconfiguration and Capacity Expansion.
2. Locate the controller on which the virtual disk resides in the tree view. Expand the controller object until the Virtual Disks
object is displayed.
3. Select the Reconfigure task from the virtual disks Tasks drop-down list box and click Execute.
4. Complete the Reconfigure task using the Reconfigure wizard.
Starting And Target RAID Levels For Virtual Disk
Reconfiguration And Capacity Expansion
After you have created a virtual disk, the possibilities for reconfiguring the virtual disk depend on the controller, RAID level, and
available physical disks.
