Critical error on RP7420

hi All,
I have a rp7420 with 8 processors that dumps suddenly without having any previous alarms or red leds,
but when accesssing MP console , i had the following fatal errors :
a. Alert Level 7 : fatal
Keyword : BOOT_NO_VIABLES_CORE_CELL
no cell rendezvoused in the partition can
be the core cell

b. Alert Level 7 : fatal
Keyword : ERR_CHECK_HPMC
an HPMC has been encountered

Does anyone have an idea about what would be the hardware problem causing sudden dumps ?

Best Regards
Charbel

Re: Critical error on RP7420

Hi Charbel,

I think your system crashed with a HPMC (High Priority Machine Check) which has often (but not always) a hardware cause (f.e. CPU problems, Cellboard Problems, Memory or IO-problems).
It seems that after the crash, a partition was build that has no Core I/O card.
Either the Core I/O is bad, or which is more probable, your Cell 1 did not join the partition and cell 0 either has no Core I/O or else is not configured to be a Core Cell.

I would strongly suggest to open a call for HP support. The logs of the MP and the HPMC log has to be analyzed to determine the problem cause.

best regards

Re: Critical error on RP7420

Hi Charbel,

Are you able to boot the system ? Is it possible to attach the ts99 file with latest timestamp ?

#/var/tombstones/ts99

From MP :

MP:CM>sl==>e (error logs)==>d (dump)

Issue can be with the core Cell as well..only these logs can determine the exact issue.

Best Regards,
