Hi,
On my HP-DL180-G6 with a HP Smart Array P212.
I can reliably trigger a controller lockup by running smartctl.
I'm trying to monitor my HDD temps using:
for ((i=0; i<8; i++)) ; do
smartctl -d cciss,$i -a /dev/sg0 | grep ^194 ;
done | awk '{t=$10; if (t > T) T = t;} END {print T}'
After a few of those runs, I get:
[ 1540.277776] hpsa 0000:06:00.0: Controller lockup detected: 0x00150028
And my disks are gone.
With linux 3.16 the whole kernel came down with NMI watchdog timeouts /
RCU stalls in the detect_lockup() worklet.
On linux 4.0 those appear to be gone, but the controller isn't coming
back either.
It this a known 'feature'; is there anything I can do to help
diagnose/fix this issue?
