Rebuilding

The array is operating and rebuilding a replacement drive or an online
spare, if one was assigned.

Logical Drive Failed

If you have one or more logical drives in an array that are not protected
by fault tolerance, the data on those logical drives are lost. The Array
Configuration Utility status window shows the logical drives as Failed.
After drive replacement, fault-tolerant logical drives rebuild and the
logical drives that were not protected become available for data (the
devices are reactivated automatically). After drive recovery and
replacement is complete for the whole array, restore lost data from your
backup data set.

If you do not replace the failed drive, the Array Configuration Utility requires
you to delete the affected logical drives.

CAUTION: Deleting failed logical drives results in a loss of all data stored on the
drive.

NOTE: Drive failure can occur on drives protected by fault tolerance if two or more
physical drives fail concurrently.

Some status indicators activate without pressing F3. For example, on the Main
Configuration menu, a FAILED status message appears beside the failed
logical drive. EXPANDING and REBUILDING messages appear next to the
array in which the corresponding activity occurs.

Handling Disk Drive Failures

If you configured your Integrated Smart Array Controller with hardware fault
tolerance, complete the following steps after a physical disk drive failure:

1. Determine which physical drive failed. On hot-plug drives in a ProLiant

server or storage system, an amber Drive Failure LED on each drive tray
indicates failure.

2. If the unit containing the failed drive does not support hot-plug drives,

perform a normal system shutdown.
