Disk Problems

Hello!

I think I may have a bad disk.  I have attached some information.  Help would be greatly appreciated!

Hello!

Bill, did you have a helpful tip?

Thanks

No clue what happened to my post...

error = 5 is an I/O error. Your disk has had an uncorrectable error so it must be replaced. The procedures are outlined in the document that Dennis listed but you need to identify whether your disk was mirrored and whether it was part of vg00. If not mirrored, you'll have to restore the entire VG from your backup tape once the disk has been replaced.

Thank you! how can I tell which volume group this disk belongs to? from what I can tell...this disk is part of the raid array and not part of vg00.

It's not a disk array, but a JBOD (likely something like a SC10).

The command

# strings /etc/lvmtab

will tell you the VG the disk belongs too.

Once found, follow the "When_good_disks_..." document.

The easier way to see what VG the disk belongs to, and what LVs are on the disk is to use the 'pvdisplay' command.

# pvdisplay -v /dev/dsk/c7t8d0 | more

Then to see if the LV or LVs that are on the disk are mirrored, use the 'lvdisplay' command.
