did you check the service processor menus were any processors deconfigured

It has you go to the service processor menus first this in done by having a ascii terminal or a laptop with a null
modem cable connected to the s1 port . use hyperterm system should not be powered on you should be able to hit any key
and get to the service processor menus if you can reconfigure the processors and then boot to SMS then power off the
system and check the processors agin in the service processors menu if it fails to boot to sms you most likly have a bad
processor card. but you may want to check the service processor error logs to see if there are any other errors.

happening by itself kind of indicates you have lost a processor bd. and need to call your service provider.
The service guide can be found at this url.
