After the disk array rebuilds itself using the spare drive, you must replace the
failed drive.
To set up a spare drive, see “Creating a Spare Drive” on page 160 (WebPAM
PROe) or page 201 (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 “Making Background Activity Settings” on
page 70 (WebPAM PROe) or page 216 (CLU).
To set Hot Spare Policy, see “Making Spare Drive Settings” on page 161
(WebPAM PROe) or page 202 (CLU).
Rebuild Operation
During rebuild:
• The alarm sounds a single short beep, repeated
• No warning icon displays over the Disk Array or Logical Drive in the Tree.
Management View reports the Disk Array’s Operational Status as OK,
Rebuilding.
• The drive carrier holding the rebuilding physical drive displays a green
Activity (lower) LED while the Status (upper) LED flashes green once per
second.
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 “Clearing Stale and PFA Conditions” on page 134 (WebPAM
PROe) or page 187 (CLU).
