FAS2020 here with 2 iSCSI ports on each controller (2 controllers). We have 2 NICs in each host server (dual port card).
controller 1 port 1: 10.250.10.1/24
controller 1 port 2: 10.250.11.1/24
controller 2 port 1: 10.250.10.2/24
controller 2 port 2: 10.250.11.2/24
NIC port 1: 10.250.10.91/24
NIC port 2: 10.250.11.91/24
However, when running System Manager to discover the FAS2020, it does not find anything. I cannot ping the SAN from the host, despite physical network connectivity wired properly.
Note that the IP addresses on the host for the iSCSI NIC ports were done in HP's Network Configuration Utility (I also declared these 2 ports as iSCSI ports in the same utility), and NOT within Windows IP stack itself.
