Morning Shawn,
Thanks for getting back with such a complete answer. Had not thought to check the multipath setup however it appears we're safe as all the hosts are targetting all 8 adapters correctly.
While I'm thinking about our MSA do you or anyone else know if I'd see any benifits from changing the controllers over to FC mode with 16G modules vs sticking on iSCSI and upgrading from the 1G Copper to 10G Fibre modules?
Thanks
