PPC system locks up after sas3ircu command is issued during RAID
Status in linux package in Ubuntu:
We have a PPC system on Ubuntu 16.04.1 LTS that will lock up if we issue a
display or status command to the RAID controller during RAID rebuild process.
The HDDs where the Operating system resides will change to RO (Read Only) once
we trigger the problem. This will only occur if the Operating System's HDDs
are also connected to the RAID controller. We've tried this problem with the
OS residing on a USB and this problem does not occur.
Apport is not writing or reporting anything in the "/etc/apport/" directory
"ubuntu-bug" is not accessible after the crash.
