We had just setup our new IP Metrocluster with FAS8230 when I accidentally did a "system power off" on one of the 4 nodes. The node has now been taken over by its partner node on the same site. I looked through the options and it seems "Storage node giveback" is the way to go, but it did not work, because it did not have contact with the partner.
Any suggestions what to do before I contact support tomorrow? I am aware there is little info available, but you know what I did, so maybe you also know what to do.
Dumb question, but did you try to power on the system? You should be able to go into SP/BMC and do something like "system console" to confirm it is responding, or check status there. You can also check "system power status".
