The Well Known Group Address is the group's iSCSI IP address. So, your group has an iSCSI IP and then each port on the controller has an IP (eth0, eth1, eth2, eth3 (depending on the model you may have 1, 2 or 4 iSCSI ports (older models could also have 3 iSCSI ports)). Be sure to always use the group's iSCSI IP in the ASM's connectivity section and not the IP from one of the eth-ports. If you did use this, disable all but 1 of your iSCSI NICs and try to ping the group IP and all port IPs. If you cannot reach one or more of them, you need to check your networking as it would be a segregated iSCSI setup, which won't work with an Equallogic implementation.
