We have a AMS500 with 13 expansion trays attached but recently we wanted to start again (re-arrange trays) so we powered down, removed all the cables and powered on with just the base controller. Now my problem is that I cannot manage the AMS500 through storage navigator as I receive the following error message from the maintenance port:
An invalid response was received from the subsystem. Confirm the subsystem status and the LAN environment and then try again.
I am now understanding I had to manually remove each tray before shutting down and removed the cabling from the expansion trays.
Can someone please help me in basically doing a hardware reset or successfully booting the base array so i can manage it and start adding trays individually again.
