We have system with hp-ux 10.20 s800. vg03 has problem.
All lvol are mirrored in 4 disk, lvol1 has first block stale and the other are current as you can see the output of lvdisplay â v

--- Logical volumes ---

00002 /dev/dsk/c3t10d0 00002 current /dev/dsk/c0t10d0 00002 current
00003 /dev/dsk/c3t10d0 00003 current /dev/dsk/c0t10d0 00003 current

we try to force to sync with lvsync and vgsync the same issue.
Remove the mirror copy from c0t10d0 and create it again with the same result we did this after replace c0t10d0 with new one.

Help

Have you issued a vgcfgrestore on your new disk after you replaced it?

I agree...

You should vgcfgrestore first then vgsync /dev/vg03 then vgchange -a y vg03.

You cant sync the disks until the new disk can "See" the LVM configuration data.

yes we used vgcfgrestore before we run vgscn and lvsync.

we replace the disk with new one

Here is a troubleshooting doc...

It is mainly for boot disks, but covers other situations...

Hi Omar,

Could you test your new disk ?

# dd if=/dev/rdsk/c0t10d0 of=/dev/null bs=1024k
