need the cluster to be applied again?


the vg03 was added into cluster and the cluster applied at that time

Now I want to recreate the vg03 with the original two disks!

After recreating the vg 03 ,need the cluster to be applied again?

Re: need the cluster to be applied again?

Didn't understand well.

What do you mean by recreate vg03? Did you destroy it using vgreduce?

Assuming, you want to use vg03 disks which were configured at the time of Cluster compilation then here it is...

If you would have saved map file using vgexport command then you can just re-import it.

No need to re-compile the cluster.

Re: need the cluster to be applied again?

If I understand your question then no, all you need to do is a vgexport of vg03 followed by a new vgimport of vg03 on each potential adoptive node. You will, of course, have to run vgchange -c y /dev/vg03 to make the VG cluster aware but this only needs be done one time because that data are carried on the disks themselves. Since vg03 was already part of some package the only cluster related commands that you need to run are cmrunpkg to start the package on your chosen node and a cmmodpkg -e to enable package switching since switching was disabled when you ran cmhaltpkg.
I do suggest that you run a vgcfgbackup on each node after you do the vgimport so that a disk can be safely replaced on any adoptive node that the package happens to be running on.
If it ain't broke, I can fix that.
