Maintain Integrity of Redundant Virtual Disks
If you have created a redundant virtual disk, the Check Consistency task verifies the accuracy of the
redundant (parity) information. This task only applies to redundant virtual disks. When necessary, the
Check Consistency task rebuilds the redundant data.
To launch the Check Consistency task:
1
Expand the Storage tree object to display the controller objects.
2 Expand a controller object.
3 Select the Virtual Disks object.
4 Select Check Consistency from the Available Tasks drop-down menu.
5 Click Execute.

Assign and Unassign Global Hot Spare
A global hot spare is an unused backup disk that is part of the array group. Hot spares remain in standby
mode. When a physical disk that is used in a virtual disk fails, the assigned hot spare is activated to
replace the failed physical disk without interrupting the system or requiring your intervention. When a
hot spare is activated, it rebuilds the data for all redundant virtual disks that were using the failed
physical disk.
You can change the hot spare assignment by unassigning a disk and choosing another disk as needed.
You can also assign more than one physical disk as a global hot spare.
Global hot spares must be assigned and unassigned manually. They are not assigned to specific virtual
disks. If you want to assign a hot spare to a virtual disk (it will replace any physical disk that fails in the
virtual disk) then use the instructions to assign and unassign dedicated hot spare.
To assign a dedicated hot spare
1 Select the disk in the Connector (channel or port) table that you want to use as the dedicated hot
spare. On some controllers, more than one disk can be selected. The disks you have selected as
dedicated hot spares are displayed in the
Disks currently configured as dedicated hot spare table.
2 Click Apply Changes when ready.
