It certainly is something to be worried about. Looks like one of your disks is on its way to the big bit bucket in the sky.

Contact HP and log a hardware call.

Hello

One of the Your disk in VG00 is H/W failed.
Maybe the disk device file is c0t8d0(?). And the disk use HSC interface because the block device number in kernel IO table is 0x1f(31).
You can confirm by lsdev command.
"lsdev | grep 31"

I think, the disk maybe have a disk performance problem.

ASAP, replace the disk and fix.

Regards.

Stefan Farrelly and sung-hoon chang...
I belive that the best action can be replace the disk.

Thank you.

Just wondering, if you know by now if this was a real SCSI error?
I need to use IT/O to monitor the syslog for errors. So if this is a real SCSI
error I would like to use the sytax from the log for my testing?

Please let me know if this problem was real.
