I'd say you have some bad spots on the disk c2t0d0 and it should probably be replaced.

This could be a hardware problem. I would check the ability of your system to read the disk in question with a "dd" command. If it is unsuccessful then you need to replace the disk. Find the disk that has the stale logical volume by doing a lvdisplay then: run

dd if=/dev/dsk/cXtYdZ of=/dev/null bs=1024k

Hi

Looks like you have a bad media(disk/c2t0d0),you can check and get that replaced.

are you running vgsync because you had a failed disk?
lvdisplay -v /dev/vg09/lvol1 | grep stale
to make sure you have a valid mirror. The you can run the dd command above check again to get the status.
If it still does not work call HP and get a new disk and vgsync the disk. If you don't have a valid mirror call HP get a new disk and put on you backup.

Extents will only become stale as mirroring fails.
Try copying some files to the volume and rin 'pvdisplay -v /dev/dsk/c2t0d0|grep stale' again. If the number of stale extents grow you definitely have a bad disk.
I would have it replaced ether way. If you have mirroring that is to protect your data and keep the system running in a situation like this. But it is only a safeguard to buy you the time to replace that disk.
