We have got several Sun blade x6250 with ESX 3.5u3 with latest updates.
We have updated firmware on one of them from ELOM 4.0.45 -> ILOM 18.104.22.168 recently.
Now a ESX server doesn't see network:
Node ISOLATED form Network. Either repair network or override agent startup ...
I executed embedded PC-Check test, it saw all four NICs and said that they were 'Success'.
Also, I cleared statistic on a Cisco Catalist interfaces where the blade was connected.
After a day 'Receive' statistic is 0
Also, I tried to load the blade with DSL Linux, it didn't see network too.
