ES47 running TRU64 5.1B failed to start after power failure..

Hi

I recently had an ES47 that failed to reboot after a power failure. After hooking up to the MBM everything seemed normal except that CPU0 did not not seem to be coming up. I cleared the error on the CPU and eventually after a few reboot cycles the system started up as normal. I'm a bit worried, is this normal behaviour or should i be concerned about the stability of this CPU ?

OK - I'll see what HP have to say.. Just wondered if anyone knew off the top of their heads if this behaviour was "by design"

Re: ES47 running TRU64 5.1B failed to start after power failure..

Hi,

What were the errors that you cleared at the MBM console ?

I can't remember exactly, but I have seen problems powering up an ES47 when it wasn't shut down cleanly. In this case, an over temperature issue had caused one of two CPU drawers to shut down...

I seem to recall it requiring a few power cycles to get it to boot up.

Cheers,

Rob

ES47 with 2 or 4 CPUs?
AS Rob said, there can some temperature issues.
Please post some more details.
