You can use the format utility:

at the command line, type format - select disk number - then choose analyze, then the type of check you wish to test.

Alternately, if you think you have a problem with a specific disk, you can check the /var/adm/messages file for errors:

# cat /var/adm/messages |grep -i error

If the OS detects problems it will report them to the syslog utility.  This will write the messages into the /var/adm/messages file on the loghost, typically the localhost.

There is a system utility called 'fdisk' which does check your disks on bootup.

If you are referring to disk space problems, you can use 'df' and 'du' to report on disk space usage.

I've found "SCSI bus MESSage in phrase parity error" in /var/adm/messages. This was 3 days ago. Now it seems to be OK.
Anyway, what does this message mean ?
Thanks jonke

These indicate bus errors as opposed to disk errors. You often get this type of error when a scsi bus is not properley terminated, or a similar kind of thing.

The fact that it happened three days ago, and has now stopped of its own accord makes this unlikely though. It is just as likely that you may have old controller firmware revisions / patch revisions - and that updating these would help.

If this only ever happened once or twice, maybe a cable became loose.

If it is a regular occurence, try to look for a pattern - perhaps when there is heavy i/o to the disk sub system at particular times.

The first thing a support desk would tell you to do - if there was no obvious physical course - would be to look at firmware and patch revisions though.

It must have been the cable for sure.
Thanks a lot.
See you to the next question.
