Cluster configuration of volume groups

[Tracey Katrusiak]

I'm in the process of configuring a cluster to house an Oracle database. The database is currently five vg's on a none clustered server. I have masked & imported the vg's to each node on the new cluster. Can I make these vg's cluster aware with out impacting the currently running database on the none cluster server?

Just doing a vgchange -c y for all the five VGs on the other nodes does not harm you. But it may fail(may work too) to do it now as the VG is currently active on another node.

You only have to do the vgchange -c y on one node and it is done for all nodes because that is part of the on-disk LVM meta-data. The gotcha is that it must be run on a node that is currently part of the cluster (ie cmcld is running on that node).
