disksuite hot spare in use recovery

I have a question regarding recovering from a disk failure with hot spares.

Configuration

Solaris 8
Disksuite 4.2.1
External D1000 diskarray

Issue

I have a partition configured with raid 5 under disksuite. To cover for hardware
problems, I have a single hot spare associated with this. The inevitable happened and a
disk failed. The hot spare worked perfectly and joined the raid 5. I have now replaced
the failed disk and want to know how I restore the hot spare disk from being in-use.

I have looked through the admin and user manuals, and cannot see a clear reference to a procedure
following an invocation of a hot spare to recover to normal state ?

Many thanks,
-Bob

The usual choice is just to make the new disk a hot spare.

ok, I think I have the solution.

Format the new disk with similiar config as one of the existing slices.

prtvtoc /dev/dsk/c1t11d0s6 | fmthard -s - /dev/dsk/c1t12d0s6

where c1t11d0s6 is an existing disk in the raid array
and     c1t12d0s6 is the failed disk.

metareplace -e d7 c1t12d0s6

where d7 is the name of the raid5 partitition and -e caused disksuite to bring the disk back online.

When all this is done, the existing hotspare reverts from being "in use" to "available", once the
syncing has completed. You can check this with

metastat
