rx7640 error on cell

Hi,

I have an rx7640, with the same problem reported here:

http://h30499.www3.hp.com/t5/Integrity-Servers/Superdome-sx2000-hardware-degraded/td-p/5243079#.UugYhqGvmCh

I get on the MP sel (I have no OS installed):

But when I go into EFI, all the hardware is there, nothing deconfigured:

On the above post, it says he fixed the problem doing a reset of the nvram of the cell, I have no idea how to reset the nvram of a rx7640 cell, anyone can help, how can I reset the nvram on the cell?.

Thanks!

Hi,

you can reset/clear NVRAM of the cell by isolating/removing the PDH battery on the cell for a minute.

Remember that you'll erase all NVRAM settings on that cell like CLM (cell local memory), fpar and acpiconfig. And if it is a partition core cell it will even lose RTC (real time clock) settings and the boot options.

So you may save these settings before you clear NVRAM.

Kind Regards

Holger

Perfect, the nvram reset fixed the errors.

Thanks

Hi Dear

I replaced the PDH Battery without saving the settings, so the server rx7640 didn't boot and the screen hold after counting CPU active set .

can you help me please

Can you share the console output showing where the boot process stops?
