Re: [foxboro] P91 Question

Is your P91 close to overloaded, without a RAID battery it has stopped doing 
buffered writes (cache) and instead all writes are being written directly to 
the HDD this is a bit slower but should not cause a P91 to crash.
So either you are overloaded or there is a problem with a power supply / 
controller as well

Subject: [foxboro] P91 Question

Folks-


I was hoping to get some ideas on tackling a recent problem at our facility.



Our P91 (Dell PowerEdge 2900) has been crashing intermittently for the past 
couple days.  We saw the below warnings in the Event Log around the time of the 
first crash.  We were able to restore the machine by cycling power.



Current capacity of the battery is below threshold:  Controller 0 (PERC
5/I Adapter).



BBU disabled; changing WB virtual disks to WT:  Controller 0 (PERC 5/I Adapter).



[The battery mentioned above is connected directly to the Adapter.  It looks 
like it is powering up a memory card that's also connected to the Adapter.]



The indication on the tower also provides an error message:



E171F PCI E Fatal Error B0 D3 F0



In the subsequent crashes, we started seeing the below error message:



Fatal firmware error:  Driver detected possible FW hang, halting FW.:
Controller 0 (PERC 5/I Adapter).



We are able to restore the machine through power cycling.  At this point, we 
reseated all the network cards.  The problem still remains.



Based on the Event Log, I am thinking that we have a bad battery or adapter 
card.  My questions for you all:



1.      Has anyone encountered this problem and, if so, how did you go
about resolving it?
2.      Do you order the replacement parts through Dell or Invensys?  I
spoke with Dell and the adapter assembly kit part number is GT281.  Does anyone 
know what the corresponding Foxboro P/N is?



Any feedback would be greatly appreciated.
