I have an equallogic with four interfaces (eth0-eth03). Eth3 is dedicated for management and its a separate subnet. Each server has multiple iscsi interfaces. The interfaces contains old IP address and new IP address which are both outside the same subnet.
I need to update the target portals and the equallogic group IP with a new IP address on the new subnet. I changed eth0, eth2 to the new IPs in the different subnet. Now all the equalogic MPIO interfaces are pointing to eth1 from the servers.
How can I minimize the downtime of manually going through the servers to point the iSCSI initiators to the new "target portal" after changing the "Group IP" in the PS Group Series Manager?
