remove the failed physical drive and install an unconfigured physical drive in
the same slot. See “Making Rebuild Settings” on page 96.
• If there is no spare drive of adequate capacity and the Auto Rebuild function
is DISABLED, you must replace the failed drive with an unconfigured
physical drive, then perform a Manual Rebuild. See “Rebuilding a Disk
Array” on page 130.
Incomplete Array
A more serious, but far less common problem is an Incomplete Array. An
incomplete array results from a physical drive that fails or becomes missing
during:
• RAID level migration
• Disk array transport
Migration
Normally, if a physical drive or the controller fails during migration, the disk array
goes degraded, and you can rebuild it.
Transport
Transport is the action of moving the physical drives of a disk array:
• To different slots in the same enclosure
• From one enclosure to another
If a physical drive fails during a transport, or you do not move all of the physical
drives to their new locations, WebPAM PROe displays an incomplete array.
When WebPAM PROe discovers an incomplete array, it displays a dialog box
asking you to:
• Click the OK button to accept the incomplete array.
• Click the Cancel button to reject the incomplete array.
Before you accept the incomplete array, be sure all of the physical drives are
present and that their drive carriers are properly installed into the enclosure. See
“Installing Your Drives” on page 20.
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 a Stale or a
PFA Condition” on page 120.
