Drive procedures 25
2.
Restore data from backup.
Case 2: The replacement drive has failed.
Verify that the replacement drive is of the correct capacity and is a supported model. If these factors are
not the cause of the problem, use a different drive as the replacement.
Case 3: Another drive in the array has failed.
A drive that has recently failed can sometimes be made temporarily operational again by cycling the
server power.
1.
Power down the server.
2.
Remove the replacement physical drive (the one undergoing a rebuild), and reinstall the drive that it
is replacing.
3.
Power up the server.
If the newly failed drive seems to be operational again:
1.
Back up any unsaved data.
2.
Remove the drive that was originally to be replaced, and reinsert the replacement physical drive. The
rebuild process automatically restarts.
3.
When the rebuild process has finished, replace the newly failed drive.
However, if the newly failed drive has not recovered:
1.
Remove the drive that was originally to be replaced, and reinsert the replacement physical drive.
2.
Replace the newly failed drive.
3.
Restore data from backup.
Upgrading drive capacity
To upgrade drive capacity:
1.
Back up all user data.
2.
Delete the existing drive configuration.
3.
Remove the existing unconfigured drives, and then install the new unconfigured drives.
For more information on removing and installing drives, see the server user guide.
4.
Create configurations on the new drives.
5.
Restore user data.
You can use the extra capacity to either create new logical drives or extend existing logical drives. For
more information, see the HPE

Moving drives and arrays
You can move drives to other ID positions on the same array controller. You can also move a complete
array from one controller to another, even if the controllers are on different servers.
Before moving drives, you must meet the following conditions:
•
If moving the drives to a different server, be sure the new server has enough empty bays to
accommodate all the drives simultaneously.
•
The array does not have failed or missing drives.
•
No spare drive in the array is acting as a replacement for a failed drive.
•
The controller is not performing capacity expansion, capacity extension, or RAID or strip size
migration.
