HI Jeef,
Looks liek you have disk problem.

Just see what are disk/PV's used by thise filesystems and then use dd to rectify the priblem.

# dd if= of=/dev/null

If this throw out any error then you have a bad disk.

REgards,

Hi Jeff,

I think you are loosing a disk.

# lvdisplay -v /dev/vg01/u1

# dd if=/dev/dsk/cxtydz of=/dev/null bs=1024k

Jeff,
looks to me like a disk/cable problem.
Anything in the EMS logs?

Yes - looks like a bad disk....

Can you do a vgdisplay -v /dev/vg01

Check the disks in a ioscan -fnC disk

Are they NO_HW?

Can you diskinfo them?

diskinfo /dev/rdsk/cXtXdX

Try the dd to /dev/null - any errors?

Rgds...Geoff
