[Cheryl Griffin]

Check the disk is vg01, c5t0d0.

Is the disk ok physically? If this were an external disk, check the cabling.

Test it wtih dd:
# dd if=/dev/dsk/cXdXtX of=/dev/null bs=64 count=1000
If successful, the results of this command will look similar to:
100+0 records in
100+0 records out

If you have diagnostics installed, are there errors be logged against the disk.

[Steven E. Protter]

If Cheryl's test isn't enough(it should be) you might want to try firing up mstm or xstm and exercising the disks.

On a physical level you might have a problem with termination or power flow through your drive cage(if applicable).

I'd be thinking about backing up any data on that drive, doing a make_tape_recovery on the box if the disk is involved in booting.

Hi,

Cheryl's test could help you to know better reasons of problem; anyway I think that it is a bad disk (/dev/dsk/c5t0d0) and should be substituted as soon as possible.

Best regards,
Ettore
