Is changing the cluster _lock_lun can be done online?

HI All,

We are Migrating Storage. all Packages are migrated to new Storage except CLUSTER_LOCK_LUN. so now we are planning to do migrate cluster lock lun. can i do by online. MY service guard version is 11.20.10 and OS is RHEL 6.3

So please guys help me to clarify about downtime required or can be done by online. 

FYI, my configuration is 

NODE_NAME node1
NETWORK_INTERFACE bond0
STATIONARY_IP 10.x.x.x
NETWORK_INTERFACE bond1
HEARTBEAT_IP 10.x.x.x
CLUSTER_LOCK_LUN /dev/mapper/SGDSKp1.

 

If i migrate to new disk, is there any chance of data loss.? 

 

Thanks in advance.
