Re: disk is currupted
After you reinstall and reconfigure your system. It might be a good idea to make an ignite image or some other backup of the system this time.

Re: disk is currupted
Are you sure you the system would stay up after having the primary root disk fail?
I just added a mirrored root disk to our rp4440. A member of HP's disk storage team told me that in the event of the primary volume crashing, the server would most likely go down, but upon reboot, the system would boot off the mirrored drive (as an alternate boot path).
Maybe this behavior is different for different servers.

Re: disk is currupted
- if the two disks are on the same bus and the failed primary trashes the bus so neither disk will work.
- the failure on the primary disk is subtle (not a simple head crash) and hangs in an unexpected way.
Of course, any mirror disk design for production will ALWAYS use separate I/O cards for each disk to avoid the problem.

Re: disk is currupted
You must watch out for this yourself, as HP has happily shipped me multiple servers (including SD and RP) with a single I/O card (with two separate scsi busses on it) for both mirrors of root, even though they put two separate cards in the I/O slots (for this purpose as per the order). So, if your machine came pre-loaded with HPUX, it may not be configured correctly, and it's up to the sysadmin to make sure that it is.

Re: disk is currupted
If the boot disk is corrupted and will not bootup, you might contact www.ontrack.com to see if they can recover your data. It is very expensive (thousands of US dollars) but they have very specialized equipment to read disks with bad spots or misaligned heads. They cannot, however, recover data which was erased or replaced by writing all over the disk.
