T5220 fails to boot

One of our T5220 servers fail to boot due to following error:

ERROR: The following devices are disabled:
XAUI1
XAUI0

I can't see any disabled components in SP console, any idea what is the problem?

Your system seems to be complaining about a couple of network interfaces which are either really faulty or have been flagged as faulty in error.

In the service processor (SP>) try clearfault and clearasrdb commands.

Then try booting.

If that fails try shutting the system down completely (unplug power) and then reconnect. Watch the SP start up and whether it marks these devices as bad (error messages). If they are marked bad:

 
SC> clearfault
SC> clearasrdb
SC> enablecomponent <device1>
SC> enablecomponent <device2>

then try boot.

I've seen this work despite the devices being marked bad during SP boot. If this works the most likely cause is a daughterboard containing these interfaces needs reseating (poor electrical contact issue).

Hope that helps.
