Re: N4000 System Crash Source: 8 = I/O Chassis Code & Physical Location

Hello Lightfoot,

it seems like an problem at left I/O Backplane with Slot2, physical Hardware Path 0/4. PCI-Card or Backplane. Was this first crash of this system? System works fine since this crash?
You have two possibilities:
-> exchange PCI-Card
-> exchange left PCI I/O Backplane

At the moment its not possible to find out more exact which part is defective.
Try and Error.
First I would exchange the PCI-Card, its easier and not so expensive.

I hope it helps You.

Mirko

Hi,
This was a replacement system for one which had totally unconnected faults.
The system had been up for about 15 Hours when it crashed.
It has now been running all day without any more problems logged.

Thanks for your help.

Ian.

Hi,
The Network Card in the Slot you said is down and so it is either that Card or PCI slot which caused the problem.

Thanks,

hi,

you can check the state of the slot with the rad commands for OLAR, take the slots on and off line.

#man rad

#rad -q

will display slots and if power is supplied to the cards, you maybe able to bring it back online.

Re: N4000 System Crash Source: 8 = I/O Chassis Code & Physical Location

Hi,

Looking at the log files, it seems that Bus check(machine check) had occured on Bus 0 which caused HPMC constituting system crash.

The physical location is pointed to the LBA for PCI slot 2 on IO backplane 1. The hardware path for PCI slot 2 is 0/5/0 (ioscan). The configuration error reported for the LBA could occure because of malfunctioning LBA itself or the PCI card installed in the slot.

To pin-point the problem, shutdown the server, remove the PCI card installed in the slot and check if the LBA is being shown in BCH -> IN -> IO
If the LBA is not appearing, then you need to replace the IO backplane. If LBA is OK, then the PCI card could be culprit.
