To set up a spare drive, see “Create Spare Drive” on page 146 (WebPAM PROe)
or “Create New Spare Drive” on page 196 (CLU).
Without a Hot Spare Drive
If there is no hot spare drive of adequate capacity, you must remove the failed
drive and install an unconfigured replacement drive of the same or greater
capacity in the same slot as the failed drive. Until you install the replacement
drive, the logical drive will remain Degraded.
• If the Auto Rebuild function is ENABLED, the disk array will begin to rebuild
automatically as soon as you replace the failed drive.
• If the Auto Rebuild function is DISABLED, you must manually rebuild the
disk array after you replace the failed drive.
To enable Automatic Rebuild, see page 71 (WebPAM PROe) or page 194 (CLU).
To set Hot Spare Policy, see page 145 (WebPAM PROe) or page 196 (CLU).
Rebuild Operation
During rebuild:
• The alarm sounds a single short beep, repeated
• No warning icon displays over the Disk Array or Logical Drive
The Management Window reports the Disk Array’s Operational Status as
OK, Rebuilding.
Important
If your replacement disk drive was formerly part of a different disk
array or logical drive, you must clear the configuration data on the
replacement drive before you use it.
See “Clear Physical Drive Conditions” on page 124 (WebPAM
PROe) or “Clear Stale and PFA Conditions” on page 174 (CLU).
