Andy,
That's probably going to depend upon what lives on 9DA1. If it's a root
filesystem or (gasp) a swap disk, then it's probably fair to say Linux
may throw in the towel. But the z/VM messages don't tell the whole
story, /var/log/messages may have more info. But as I say, if it's the
root filesystem it may not be able to write the messages, then there's a
vicious cycle and boom!
I'd say check into what's causing the IFCC problems.

My background is z/OS so please excuse me....
Question:
We have recently taken many hits (paths being lost, chip,ids etc
see below) for some of our DASD which z/VM sits on and Redhat, we are
looking into why. Each time we take such a hit we have lost different
instances of zLinux. Now I understand the concept the OS z/Vm does the
I/O and recovery through MIH etc. I am to assume then Redhat or SUSE any
linux running under z/VM is dependant on the operating system for
recovery. So it normal when taking a hit like the one below to loose a
zLinux instance?
To me this sounds normal but wanted to make sure it wasn't something we
missed. We are going to try to set up something in TSA to better monitor
it but again just checking.
for example
