How to run a health check on disks?

Hello,

I'm facing some problems installing HP-UX 11i v3 on a RX2660 server. I got an error output when installing a file set of kernel. Something like "unable to write on disk...".

I'm trying to run a health check on the disks using the Offline Diagnostic and Utilities CD but I cannot find the modules related to disks as DISKEXPT and DISKUTIL.

Anyone knows how to run a offline health check on disks? What else can be done in this situation?

Thanks in Advance

Here is a doc with a chapter dedicated to recognize a disk that it is failing:

Re: How to run a health check on disks?

If the server is up and running (Online) there are different commands you can run to look at different things.I'd do a man or -h after each command.
There are new options with ioscan like ioscan -P health and ioscan -m lun. Do a man on ioscan to see some of your new options.

There is also scsimgr commands which I have found very helpful in the past.
ex. scsimgr -p get_attr all_lun -a wwid -a state

If they are sas disks you have sasmgr
ex. sasmgr get_info -D /dev/sasd0

And you could also possibly look at stm or cstm for hardware errors.

best way to check the disk integrity is run dd during the off business hours :)
