MSA500 G2 and multipath

[cristian mazza]

I could use for Server A the path /dev/cciss/c1d0p1 (first smartarray) and for Server B /dev/cciss/c2d0p1 (second smartarray).

do you think that this may be a good solution? or not?

do you think that the quorum server may be a preferred solution?

Your LockLUN solution is fine.

On Quorum Service vs LockLUN. Quorum service is easier to manage in some ways, but it must reside on a computer outside of the cluster. Some customers do not like that. In some cases, failover can be a little faster with Quorum Service. If the server running QS fails, the cluster keeps running (if there are no there failures within the cluster). if that computer does fail, it can be reapired without any impact at all to the cluster.

Since LockLUN is entirely within the cluster there is no extra hardware. If there is a failure on the single path to the LockLUN because of an HBA failure, the repair should be scheduled. In order to do that repair, the node needs to come down so there is some impact since the packages need to be moved over to the other node.

With that information, you should be able to make a decision appropriate for your environment.
