multipath, failover, replication

[fcl]

Hi,

How can I do failover between two 7400 for a replicated VLUN ?

Hosts are XenServer / iSCSI / multipath.

I think I can configure "standby" paths and then script a path (with replication and vlun switching) switching...but it seems to be a bit tricky. Is someone doing that ?

Thanks in advance

I am not sure what you are asking? You have 2 7400 arrays and want to fial over a single VLUN to another 7400? Are you asking about Peer Persistence?
