Check the vgdisplay -v output for #of physicals vs #of disk seen. If there is a mismatch attempt to vgchange -a y /dev/vgxx to see if you can bring the disk into the config.

Then we will take it from there if it does not resolve.

You need to reactivate the VG after doing a vgcfgrestore so that the VG knows the new disk is active.

# vgchange -a y vg00

Then try your vgsync, pvdisplay, etc.

Shalom,

All disks need pvcreate command to be run on them prior to any other commands.

Hi,

Patrick: It worked well.. I reacvtivated the vg00 and then vgsync. it was cool.

Steven: I didnt do pvcreate on that disk, but still it worked.

Thanks a lot guys....
