Hello,
This is a bit dumb and confusing question/inquiry.

I have a dual vio setup in my environment on which i have several Lpars.
I am planning on upgrading my Vio's from 2.1 to 2.2

My colleague told me before he left for vacation that there is an adapter issue on vio1 and NIC card for ent15(SEA) needs to be replaced, before i begin the vio upgrade process.

However i am unable to determine the error or issue that he saw in the system for any issues with ent15(SEA).

I need assistance in troubleshooting this SEA and seeing if there is something wrong with it.

Thanks.

Hello wmp.

The issue is that ent15 is in standy mode.
I was going to fix that status with sudo chdev -l ent15 -a ha_mode=auto  but i was told not to do so by my colleague who went on vacation, who mentioned that the NIC for ent15 needs to be replaced.

[padmin:/home/padmin]lsdev -dev ent15 -attr

[padmin:/home/padmin]

I did not see any errors in errlog for ent14 the real adapter of ent15.

Please advise on how further it can be determined to see there is an issue with ent15, that it requires the NIC for ent15 be replaced.
