I have a 5 Disk RAID array which uses the Adaptec 2100S SCSI controller. The RAID is showing one of the disks as failed and the RAID as degraded. I have 3 spare disks so no problem I thought Id just swap the failed disk for a spare. All 5 disk & spares are Ultra 160 36Gb disks of the same make.

I am unable to assign the replacement disk to the Array. I've followed the Adaptec Instructions, below but I don't get the rebuild option. Interestingly both the failed disk and new disk show up as Ultra2 80MB/sec not Ultra 3 106MB/sec like the working 4 disk. I can't assign the new disk as a hot spare because I get a message "not large enough to protect any of the arrays" I assume its because all 5 hotswap bays were used.

Any help  much appreciated. Thanks

To rebuild an array, follow these steps:
1 Replace the failed drive according to the procedure in your
hardware documentation.
2 After the failed drive has been replaced, select
Logical Configuration View in Storage Manager.
3 Double-click the array group icon to open the Array Group
Information window.
4 Click Rebuild in the Array Group Information window to start
the rebuild process.
