I have a single iSCSI SAN array and two host in my cluster and want to add a third host. The initial configuration has the cluster directly connected to the SAN but adding a third host we will have the SAN and the Hosts connected to two switches which means we will need to reconfigure the IP addresses on the SAN controllers and on the Hosts. Will breaking the iSCSI connection when changing the IP addresses cause us to lose the VMs that are currently running off of the SAN or is it just of matter of reconnecting iSCSI sessions once the IP Addresses are reconfigured?
Please let me know if there is any other info I can provide
