• 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 160.
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 critical, 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.
Accepting an 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 Physical Drives” on page 21.
If you choose to accept the incomplete array:
1. Click OK in the incomplete array dialog box.
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 147.
