Setting an Alias
An alias is optional. To set an Alias for a physical drive:
1. From the Main Menu, highlight Physical Drive Management and press
Enter.
2. Highlight the physical drive you want and press Enter.
3. Type an alias into the field provided.
Maximum of 32 characters. Use letters, numbers, space between words
and underscore.
4. Press Control-A to save your settings.
Clearing Stale and PFA Conditions
The Clear Stale and Clear PFA functions only appear when those conditions exist
on the physical drive. To clear a Stale or PFA condition on a physical drive:
1. From the Main Menu, highlight Physical Drive Management and press
Enter.
2. Highlight the physical drive you want and press Enter.
3. Highlight Clear Stale or Clear PFA and press Enter.
If a physical drive is still online and shows a PFA error but “Clear PFA” does
not appear, use PDM to copy the data to a new physical drive. See “Running
PDM on a Disk Array” on page 237.
If a physical drive is offline and shows a PFA error, rebuild the disk array.
See “Rebuilding a Disk Array” on page 236. After rebuilding, the drive shows
Stale. Run Clear Stale then run Clear PFA.
If the physical drive with a PFA error is a spare, you must delete the drive as
a spare, then Clear PFA is available.
After you clear a PFA error, watch for another PFA error to appear. If it does,
replace the physical drive.
Forcing a Physical Drive Offline
This function enables you to force an online physical drive to go Offline.
The Force Offline function appears only for physical drives that are assigned to
disk arrays.
Caution
Forcing a physical drive offline is likely to cause data loss. Back up
your data before you proceed. Use this function only when
required.
