What version of HP-UX do you have?

Could you post a "ioscan -fnCdisk"?

The "ioscan" recommended by RuBiCK will tell you about your discs and DVD drive. It will also force HP-UX to look.

"iostat" with no parameters always produces the same wrong figures. It needs to be run for a sample period to produce useful figures.
The output from "sar" can be more useful but it does not report on idle discs.

For a quick test you can try these two commands to sample disc performance at 10 second intervals twice.

Code:

iostat 10 2

sar -d 10 2

A realistic sample would be for a longer period.

I'm wondering if alert0919 was using 11.31 because he has c#t#d maybe cdrom and disk# (agile view adressing) and he's asking if disk# are physical disk.

alert0919, could you post our suggestions?
