ILOM IP address not responding at Sun T5220 after network outage

[Bill Mackler]

Hi,

There was a network outage at our data center. It lasted for about 8 hours.
After the network was brought back up, ILOM IP is not accessible and cannot be pinged. Network connection checked OK between the ILOM and the network switch. There's no change at the network side or at the ILOM configs.
We rebooted the ILOM via "-> reset /SP" but the ILOM IP is still not pingable or accessible. The ILOM is up and running. I can attach my laptop for the serial connection to the ILOM and issue ILOM command.
Would anyone know how we can resolve this ILOM IP address issue ?


Thanks,

Bill

Do you have the latest ILOM firmware installed?

No. the ILOM firmware hasn't been upgraded since we "inherited" the T5220 a while back. Would you know how to check the firmware, what version to get and where to download ?

Thanks,

Bill

Type version :-)

http://docs.oracle.com/cd/E19569-01/820-1188-12/core_ilom_firmware.html

If you have an Oracle account you will be able to download it

have you actually checked to make sure the network settings were not lost?
It's been more than once I've seen configs just vanish off ILOM.

[Bill Mackler]

I did issue -> show /SP/network
all network configs are still there.

To be on the safe side, I also issued the following to make sure
that the network is enabled :
-> set /SP/network state=enabled
-> set /SP/network commitpending=true

Unfortunately, none of the above seems to work either.

Thanks,

Bill

Well, simple then.

If you are 100% sure the network config for the ILOM is there, then you
have a hardware problem and the ethernet port on it is blown.

You never really explained this in any detail:

"There was a network outage at our data center. It lasted for about 8 hours."

I find it kind of odd a network outage at a data center took 8 hours to fix,
unless it was extensive damage, from a lightning strike maybe? Of course a
backhoe down the road tearing out a fiber cable could be to blame also.

We took a hit in 2008 from a near by lightning strike and ethernet was the
only casualty. Most of our Cisco switches were showing green when something
was plugged into a port, but the transceivers must of been blown inside
because there was no traffic, no matter what you tried. Same with one of the
old Sun 280r's and some of those old Cobalt Raq4 things.

Look, all you have to do is configure the ILOM from the serial side to use
an internal 192.168.1.x address, set up a laptop the same way, plug one into
the other using a regular eth (or xover) cable and see if they talk.

If you still can't ping it with a direct connection, your eth port on it is
shot. End of story.

It's not likely to be firmware or software at this point.

Get an explanation of the 8 hour outage and what caused it, if the word
"lightning" is used as any part of it, assume the worst.
