Running 2.1 two nodes (currently in eval mode) did an upgrade, it upgraded the secondary ok, failed upgrading the primary. Long story short, tried to upgrade again, it failed/crashed (no obvious error message), tried upgrade from CLI instead, it hangs at "step 1. stopping ISE processes". I tried doing an "application stop ise" as well, it also just sits there and does nothing. I've left it overnight its still hung. I now effectively have two nodes, one at 2.2 and one at 2.1, with the inability to upgrade the earlier revision one. How can I kill these processes? I believe there are some patches that help with the 2.1 to 2.2 upgrade, but then I'm assuming these will also need ISE to be stopped first. Catch 22.
Any ideas??? This is driving me mad!
