lan card unreachable but obviously working
Hello. I rebooted my superdome vPar 11.23 server before patching today, came back up OK. Then I patched it with the latest patch bundle (alongside with another server). The other one came back up OK (like many did before), but this one didn't.
I am getting connections timed out, ping isn't working, looks like the cable in the datacenter popped out of the machine right after patching. On the server (via console), I can see that the lan card is claimed, in lanadmin it is UP, I can ping the network IP but I only get the response back from my lancard. I didn't modify any settings. Could someone please give me some troubleshooting ideas? How to tell whether something happened between the server and router, or within the server/lan card? thanks.
now some outputs

Re: lan card unreachable but obviously working
lanadmin -r 0 (resetting the card) won't solve the issue ?
And what will "ping 172.25.92.255" show ?

resetting the lancard didn't work. I should've mentioned that I tried rebooting the box about 2 times.

Re: lan card unreachable but obviously working
You might try linkloop using the MAC address to bypass any switch or router issues.
linkloop 0x001CC4C51BB6 (loopback on self)
linkloop 0x001CC4C51BB7 0x0017A4A4A4C6 0x0017A4A4A4C7 (try the other NICs)
then try other NIC MACs on the same switch.
