Re: System Crash

You say SCSI bus and mention MSIOP but, aren't SCSI and IOP's deprecated on
p7?
It should have a Dual IOP-less SAS controller. If we're talking about the
CEC of course.
I hope you get it back up quickly. I'm waiting on a client that left the
"apply PTF" stage just for when i had to add some cards to the enclosure
(thereby giving me enough spare time to post this reply...). And i found
out that an IBM CE had replaced batteries just a few days ago. Weird thing?
C19 was reporting as unknown and a PCI bus failure was being logged.
Re-seated said card and everything went back to normal. Now, C19 is one of
the 2 controllers that manage the internal disks on the 720 so the system
had been working with one controller for the last 38 days. So an IBM CE
left a card unseated AND didn't check VIOS' diag tool to check everything
was OK after replacing the batteries.
Maybe it's something like that? you were working on one controller and it
threw a fit?

Best of luck and hope it's quickly fixed.

Our Power7 server CRASHED again. The second time in the last 3 months!

The first time was LIC related, this time it was a hardware failure.

When one of the mirrored load source drives failed it threw some "noise"
out on the SCSI BUS which caused the MSIOP to fail and the system crashed.

Do you think this has anything to do with it being Friday the 13th?!?

Has anyone ever experienced anything like this? You'd think that mirrored
disk protection for the load source disk would be sufficient to protect
against a system crash. Apparently not!
