I am running Irix 6.5.27 on two SGI Origin 350 's as master and clone
with 4 United Digital Raids, of which are separated into 4 x 1.8TB of
which are mirrored. Also connected is 2 Overland Neo tape units of
which contain 3 drives in each. The problem we had the other weekend
was that the SGI went into a panic and decided to re-boot itself, after
which the Raids went into a revive. We also had temperature warnings in
the analysis.0 log located in /var/adm/crash. Just before the panic
there was a fibre channel error of which was:

Jul 8 18:32:57 6A:uk-pk-sgi-01 unix: qlfc23:

abort iocb, port id 0x10a00, request 0xa800000052824900, cookie

I have managed to find out that this path is connected to the second
Overland Neo tape unit and drive 2. We were having problems with this
drive during the day and prior to the event the drive was taken offline
and placed back online again to try and eliminate the retsore errors we
were getting from that drive.

Here is the rest of the core summary log:
