Yesterday, I was upgrading my 4th controller out of 4 which essentially has nothing on it. Opened a TAC Case about something else, and I decided to upgrade the firmware to 4.0.217 from 4.0.1xx? (don't remember this early). I decided to upgrade one as a test before I attempted the production controller.
Finally got TFTP working, software loaded, came to the save and reboot prompt, pressed that, and I haven't seen it since.
I cannot browse into it, however if I drive all the way to where it is, I can console into it and it appears to be there. I see the new firmware version etc.
The kicker is I cannot browse into my production controller either. The two in the middle are just fine. both affected controllers are on separate Wism's.
I was going to attempt a 'reset system' in the number 4 controller until I saw that it apparently jacked the one currently in use. I pray that nobody else has been through this but in the event that they have, short of issuing a change control, rebooting the controller, and hoping that they all come back...I would like to hear the outcome of anyone else's experience.
I'm about ready to pack this POS up and send it back. I have never seen this amount of problems introduced in an autonomous system. And if one of those does go bad - It doesn't take the whole network with it./rant
