Hi I have a 2 node fail-over cluster running 2008 R2 Server core cluster, recently we purchased a SAN switch since we needed to add another node to it. we need to have zero downtime when connecting the new SAN switch. since MPIO is in place we can unplug Fibre channels one by one. i would like to know the status (active path/passive path) of MPIO when i disconnect one FC card.
Thank you
