Change SAN configuration

[bwb]

Is it safer to shutdown the VM before to perform this operation ?

Another question about this migration :

is the virtual IP only available on the network only when replication task is started ?

ex:
can i setup all settings for replication (including virtual IP as target) on 1 SAN without starting replication task
then configure the ESX initiator with the virtual IP target and run my VM ?
and later configure a 2nd SAN for replication and then start the replication task

The virtual IP is only available when the failover service is running.
