How to resolve LVM error in powerHA

In the event you run into the following error:

    cl_mklv: Operation is not allowed because vg is a RAID concurrent volume group. 

This may be caused by the volume group being varied on, on the other node. If it should not be varied on, on the other node, run:

    # varyoffvg vg 

And then retry the LVM command.

BUT if it continues to be a problem, then stop powerHA 7.1 on both nodes, export the volume group and re-import the volume group on both nodes, and then restart the cluster.
