Rebuilding a Disk Array
When you rebuild a disk array, you are actually rebuilding the data on one of its
physical drives.
If there is no spare drive of adequate capacity, you must replace the failed drive
with an unconfigured physical drive, then perform a Rebuild manually.
See “Replacing a Physical Drive” on page 107.
To perform a manual rebuild:
1. From the Admin menu, choose Background Activities .
2. Mouse-over Rebuild and click the Start button.
3. From the Source Physical Drive dropdown menu, choose a Source disk
array and physical drive.
Arrays have an ID No. Physical drives have a Seq. No.(sequence number)
4. From the Target Physical Drive dropdown menu, choose a Target physical
drive.
5. In the Confirmation box, type the word “confirm” in the field provided and
click the
Confirm button.
When the disk array is rebuilding:
• The disk array shows a green check icon and Rebuilding status.
• Logical drives under the disk array continue to show a yellow ! icon
and Critical, Rebuilding status.
• If the buzzer is enabled, the Pegasus unit emits two quick beeps every
five seconds. When the beeps stop, the rebuild is done.
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
