I was wondering if anyone had any positive experience with a quad supervisor upgrade. We performed one last saturday on our 6807 from 15.2(1)sy1a to 15.2(1)sy4 and it turned into a bit of a mess.
The first problem was one of the line cards went into an FRU-Power error and won't load after the "issu commitversion" step requiring an RMA.
The second problem was the 2 ports on the standby hot supervisor on the formerly active now standby chassis wasn't joining the VSL port channel. So they are also going to RMA that supervisor.
VSL Connections: Yellow and green link will now not join the VSL port-channel. https://imgur.com/a/pn7jO
In the end we have 2 slots that have to be RMA'd and im hesitant to do another ISSU upgrade (and actually cant until the VSL links get repaired)
Is this par for the course with ISSU or did we hit the lotto?
Thanks in advance.
