Assign Global Hot Spare
A hot spare is an unused backup disk that is part of the array group. Hot spares remain in standby mode. When an array disk in a virtual disk fails, the
assigned hot spare will be activated to replace the failed array disk without interrupting the system or requiring your intervention.
You can change the hot-spare disk assignment by unassigning a disk and choosing another disk to assign, as needed.
To assign a global hot spare, perform the following steps:
1. Right-click the array disk that you want to use as a hot spare.
2. Click Assign Global Hot Spare.
The Assign Hot Spare dialog box appears.
3. Confirm the successful completion of the operation by checking the properties displayed in the right pane.
The status of the array disk must be Ready and the type must be Spare Array Disk.
Unassign Global Hot Spare
The Unassign Global Hot Spare command unassigns the hot-spare disk. To unassign the hot-spare disk, perform the following steps:
1. Right-click the disk that is assigned as a hot spare.
2. Click Unassign Global Hot Spare.
3. Confirm the successful completion of the operation by checking the properties displayed in the right pane.
The status of the array disk must be Ready and the type must be Array Disk.
Prepare to Remove
Use this procedure to prepare for removing an array disk from a controller.
1. Right-click the disk that you want to remove.
2. Click Prepare to Remove, and then click OK to continue.
When the lights on the disk you have prepared to remove stop blinking, the disk is ready to be physically removed. The disk will not be listed in the array
group.
