I have a customer with two V7000s using Metro Mirror, replicating over Fibre Channel between rooms on their site.
They wish to move into Hyperswap to achieve better availability. They have enough extra SAN fabric ports to cable all 4 fibre ports into the SAN fabric in order to isolate host IO and Hyperswap IO.
I am pretty sure that the work involves temporarily losing DR while Hyperswap is being configured.
However, I am unclear as to what state I need to return the DR V7000 so it can be added in to the Live V7000 using 'Add Enclosure'. Do I have to delete all Volumes, Hosts and Mdisks on the current DR V7000 before it can be added in as site2 clustered with the Live V7000?
I am comfortable with having to recreate Volumes, but it will add extra time to the plan if I have to delete the entire Mdisks and then recreate after the enclosure has been added into the cluster with Live.
Thanks in advance for the advice.
