Silencing the Alarm

An alarm will sound when an error occurs. To silence the alarm, use BIOS RAID

Configuration utility. See “Using the BIOS RAID Configuration Utility” on page 65.

Recovering From a Disk Drive Failure

This section explains how to recover when a disk drive fails:

■ If the array was protected by a hot-spare (see “Failed Disk Drive Protected by a

Hot-Spare” on page 80).

■ If the array was not protected by a hot-spare (see “Failed Disk Drive Not Protected

by a Hot-Spare” on page 81).

■ If there is a disk drive failure in more than one array simultaneously (see “Failure

in Multiple Arrays Simultaneously” on page 81).

■ If it is a RAID 0 array (see “Disk Drive Failure in a RAID 0 Array” on page 81).

■ If multiple disk drives fail within the same array (see “Multiple Failures in the

Same Array” on page 82).

Failed Disk Drive Protected by a Hot-Spare

When an array is protected by a hot-spare, if a disk drive in that array fails the hot-

spare is automatically incorporated into the array and takes over for the failed drive.

▼ To Recover From a Disk Drive Failure

1. Remove and replace the failed disk drive (following manufacturer’s

instructions).

2. Choose the correct step:

■ If copyback is not enabled—In the Sun StorageTek RAID Manager graphical user

interface (GUI), remove the ‘hot-spare’ designation from the original hot-spare

(the disk drive that was built into the array). Then, designate a new hot-spare to

protect the arrays on that HBA.
