First of all you need to tell what controller you have (e.g. an smartarray).

Do

# ioscan -fn

and look for a /dev/ciss_ device.

The use

# saconfig /dev/ciss_

# sautil /dev/ciss_

and post the results to give us more details.

Hope this helps!

Torsten.

Re: how to configure raid5 with hot spare for MSA 30 in HP-UX server

First I would pull the bad disk (ID 1).

This bad disk probably block the entire bus.

A single failed disk should never turn a RAID 5 into failed.

Does anything change?

Does the spare kick in?


Please come back once the disk is replaced and the RAID is still failed.

Hope this helps!
Regards
Torsten.
