PDHC on a PA RISC system cellboard
I've had quite an issue with a 7420, which turned out to be due to a faulty PFHC on the cellboard. This only showed when we had to shut the system down and tried to restart it.
The cause of this, if I udnerstood it correctly, is usually due to a powerpeak or firmware upgrades. Since we did not do any firmware upgrade, the power peak is the only option left. Altho I do not know of any power issues in the datacenter, I would like to check other systems if their PDHC is functioning correctly.
Is there any way I can check these without having to hardboot the system end seeing it not start up again?
Thanks,

Re: PDHC on a PA RISC system cellboard
What kind of messages did you receive? VRM related?
Hope this helps!

Re: PDHC on a PA RISC system cellboard
during the search for the borken part, we never got any clue that it could be the PDHC that was broken, still only guessing it was broken before the VRM caused the system to panic.
My only concern now is that I do not know how to check my other systems for a possible faulty PDHC without having to shut it down completely first.

Re: PDHC on a PA RISC system cellboard
All PDHC related part are on the daughter board. Even this board or a VRM can fail and bring the server down.
Check with PS and DE command.
Hope this helps!

Torsten.

Re: PDHC on a PA RISC system cellboard
Access the MP Command Menu and run SYSREV to report the versions on each of the components.
The PS and DE commands will also report particular firmware revisions.
