0) cmhaltcl
1 ) cd /etc/cmcluster
2) cmgetconf CLS.ASC
3) edit CLS.ASC and locate:
FIRST_CLUSTER_LOCK_VG
and in each node section:
FIRST_CLUSTER_LOCK_PV
4) identify a new VG that will remain under cluster control after the SAN migration has completed
5) identify a PV in that VG (in /etc/lvmtab)
6) edit the CLS.ASC file, with the new lock VG reference and for each node, lock PV reference.
7) cmcheckconf -C CLS.ASC
8) If step 7 succeeds, halt the cluster and apply the configuration change
9) cmapplyconf -C CLS.ASC
