hi,

http://docs.hp.com/en/diag/ems/cmc_em.htm

check the event ID : Event 100642

i would recommend to contact your support company ( usually HP ) to check the CPU health.

the offline check will be required.

Is this a vpar setup?
Any vpar abruptly hanged & crashed the whole npar?

Normally, if your vpar hangs, then there are some RACE condition patches, which logs the error in MP.

Many times, we are not getting logs captured for cache in MP logs. HP orders the whole cellboard.

Thanks,
Vivek
