Hi, Hopefully somecan help me regain access to my PS4100. In moveing a single member in a one group to a new v4 ip i changed the ip on the second nic to the new address (10.5.x.x/16) and the group IP to (10.5.x.x/16) however although the SAN is responding to pings on these new IP addresses the first nic  which is still on the old ip range (10.10.x.x/16). My problem is the web gui is failing to respond. I have connected the serial connector and can log into the SAN, but do not know the commands to amend the first nic to change its ip. If possible at all ?
