vglock..

[Matrah]

Hi,
Can i need to activate the vglock before running cmapplyconf in order to distribute the binary file ?( my vglock is a data disk but my question is in general )

Thanks

If the cluster lock disc has not been activated before on this cluster, you need to activate the cluster lock vg BEFORE doing a cmapplyconf. This backs up the CL information so that it can be recovered if the disc is replaced and a vgcfgrestore is done.
If the cl disk has already been marked in the past, then ther eis no real need to do it, but it is something I recommend gets done anyway, just to make sure.

You have to activate the lock VG before doing a cmapplyconf. You should be able to do this using the command vgchange -a y VGLOCKNAME. This is so that the lock VG is marked as such...if it has already been marked then there is no need to do this.

It will not let you to do it by mistake. cmapplyconf (cmcheckconf) is going to give out the error if you do not activate the CLUSTER_LOG_VG

Yes, you need to do so.

The cluster-lock structure is normally installed by activating the
cluster-lock VG, then performing cmcheckconf/cmapplyconf pair.

The cluster-lock cannot be reinitialized while the cluster is running however. The cluster must be brought down, the cluster-lock volume group activated, and then cmapplyconf should be executed. If the cluster-lock VG was
already clustered, it must be unclustered before attempting to activate it:

# vgchange -c n /dev/
