Chapter 10: Solving Problems l 55

If the controller fails to rebuild the array, check that the cables, disk drives, and controllers are properly installed and connected. Then, if necessary, use Adaptec Storage Manager to rebuild the array. For instructions, refer to the Adaptec Storage Manager User’s Guide or online Help.

Failure in Multiple Arrays Simultaneously

If the disk drive failure in more than one array at the same time (one failure per array), and the arrays are protected by hot spares, the controller rebuilds the arrays with these limitations:

●A hot spare must be of equal or greater size than the failed disk drive it’s replacing.

●Failed disk drives are replaced with hot spares in the order in which they failed. (The array that includes the disk drive that failed first is rebuilt first, assuming an appropriate hot spare is available-see bullet above).

If there are more disk drive failures than hot spares, see Failed Disk Drive Not Protected by a Hot Spare in previous section.

Disk Drive Failure in a RAID 0 Array

Because RAID 0 volumes do not include redundancy, if a disk drive fails in a RAID 0 array, the data can’t be recovered.

Correct the cause of the failure or replace the failed disk drives. Then, restore your data (if available).

Multiple Failures in the Same Array

If more than one disk drive fails at the same time in the same RAID 1 array, the data can’t be recovered.

Correct the cause of the failure or replace the failed disk drives. Then, restore your data (if available).

In some instances, RAID 10 arrays may survive multiple disk drive failures, depending on which disk drives fail. For more information, refer to the Adaptec Storage Manager User’s Guide or online Help.

Resetting the Controller

This section explains how to reset (or flash) your Adaptec HostRAID controller. You may want to do this if the controller becomes inoperable, or if a firmware upgrade is unsuccessful.

To reset your Adaptec HostRAID controller:

1Download the firmware version currently installed on your controller from www.adaptec.com.

2Extract the downloaded files to a folder on your local hard drive (for example, C:\Download\Drivers).

3Create a bootable MS–DOS floppy disk and copy the AFU.exe file to it. Copy the first firmware image to the same floppy disk.

4Create additional bootable MS–DOS floppy disks and copy each additional firmware image to its own floppy disk.
