How to Replace a Failed SPARCstorage Array Disk in a RAID5 Metadevice (DiskSuite Tool)

When setting up RAID5 metadevices for online repair, you will have to use a minimum RAID5 width of three slices. While this is not an optimal configuration for RAID5, it is still slightly less expensive than mirroring, in terms of the overhead of the redundant data. You should place each of the three slices of each RAID5 metadevice within a separate tray. If all disks in a SPARCstorage Array are configured this way (or in combination with mirrors as described above), the tray containing the failed disk may be removed without losing access to any of the data.

Any applications using non-replicated disks in the tray containing the failed drive should first be suspended or terminated.

1. Refer to "" through Step 9 in the previous procedure, "How to Replace a Failed SPARCstorage Array Disk in a Mirror (DiskSuite Tool)".

   You are going to locate the problem disk and tray, locate other affected DiskSuite objects, prepare the disk to be replaced, replace, then repartition the drive.

2. Use the metareplace -e command to enable the new drive in the tray.

3. Refer to Step 12 through Step 16 in the previous procedure, "How to Replace a Failed SPARCstorage Array Disk in a Mirror (DiskSuite Tool)".
