Operating Systems HP-UX corrupt disk Post 302577547 by methyl on Tuesday 29th of November 2011 10:22:54 AM

I think that the guys on ittoolbox.com are giving you the same sort of advice (get an Ignite backup of vg00 , and also get a backup of your data):
http://unix.ittoolbox.com/groups/tec...-of-os-4515267

Running a computer server with no resilient disc system and no backup is not sensible. You need both.

Oracle used to advise against RAID disc systems (notably software RAID) on performance grounds. They also used to made recommendations about the file mapping across multiple discs. A modern hardware RAID system or a SAN is transparent to Oracle.

Just in case you don't have a copy, this unsupported document "When good disks go bad" is a good read. Apart from showing how easy it can be to recover in a resilient system, it also shows the commands to test a disc with "dd".

HP links can go dead, so do save a copy.

I've seen your error message both from a disc with a tight SCSI cable ... and from a disc which failed totally a few minutes later. You can also get this message (followed by a SCSI reset) if you replug SCSI devices with the power on.
