SolutionYes, you can do this but you must recreate the vg info whit same configuration on all nodes.
so, on the server with the pakage you can do:
1) lvreduce -m 0 /dev/vgxx
2) vgreduce /dev/vgxx /dev/dsk/cXdXyX
3) vgexport -v -p -s -m /tmp/vgxx.map /dev/vg00
4) rcp /tmp/vgxx other nodes
on the other nodes:
1) vgexport /dev/vgxx
2)mkdir /Dev/vgxx
3)mknod /dev/vgxx group c 64 0x
2) vgimport -v -m /tmp/vgxx.map /dev/vgxx
and thas all
bye

Re: Mirrored LV's
I have followed the procedure Domenico documented many times in the past.
Follow that and you shouldn't have any problems.
Good Luck!

Re: Mirrored LV's
Yes you can, but be careful.
Reduce the mirror on the server where the vg is active.
Remove the disk which not containing the cluster lock (check in /etc/cmcluster/cluster.ascii)
For each lv :
#lvreduce -m 0 /dev/vgx/lvolxx
then
# vgreduce vgx /dev/dsk/cx...
then generate a mapfile
# vgexport -p -v -s -m mapfile.vgx vgx
send this mapfile on the other node :
# rcp mapfile.vgx nodeB:/tmp/mapfile.vgx
Then on the other node :
# vgexport vgx
# mkdir /dev/vgx
# mknod /dev/vgx/group c 64 0x.....
# vgimport -v -s -m /tmp/mapfile.vgx vgx
Now you can use the pv
