Rebuilding a Logical Drive

The remedial action for a critical logical drive is to rebuild it, meaning the data from the failed physical drive is rebuilt onto a spare or replacement physical drive.

Spare Drive Available

The SuperTrak Controller will rebuilt a logical drive automatically using a spare drive, providing:

•A spare drive is available

•The spare drive is the same size or larger than the failed drive

•The Auto Rebuild setting is enabled in WebPAM PRO. Enabled is the default setting. See “Making Background Activity Settings” on page 133.

If the above conditions are met, the SuperTrak controller automatically rebuilds the logical drive with the hot spare. After the rebuild is done, you must replace the failed drive with a new physical drive.

Depending on your spare drive settings, you might make the replacement drive the new spare drive, or the original spare will transition back to its original status. See “Creating a Spare Drive” on page 97 or page 173. Also see “Hot Spare Drive(s)” on page 239.

No Spare Drive Available

If a spare drive is not available, you must replace the failed drive. Then the SuperTrak controller will automatically rebuild the logical drive using the new physical drive, providing:

•The new drive is the same size or larger than the failed drive

•The Auto Rebuild setting is enabled in WebPAM PRO. Enabled is the default setting. See “Making Background Activity Settings” on page 133.

Manual Rebuild: SuperBuild Utility

In some cases, you must start the Rebuild manually. After replacing the failed drive with a new drive of equal or larger size, take the following actions:

1.In the Main Menu, highlight Disk Array Management and press Enter. The Disk Array Management screen displays.

2.Highlight the Disk Array with the failed drive and press Enter. The Disk Array Info and Setting screen displays.

3.Highlight Physical Drives in the Array and press Enter.

Note the ID numbers of the physical drives that are still functional
