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 Shaun -----Original Message----- From: foxboro-bounce@xxxxxxxxxxxxx [mailto:foxboro-bounce@xxxxxxxxxxxxx] On Behalf Of Chaiket, Thom Sent: Friday, 4 May 2012 6:35 AM To: foxboro@xxxxxxxxxxxxx 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. t Thom Chaiket, PE, PMP SCADA Engineer Bergen County Utilities Authority (o) 201-807-5814 (c) 201-954-0301 (f) 201-807-8633 _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
