I'm running LUbuntu x64 20.04.1 kernel 5.4.0-52-generic with an Adapted
ASR-51245 hosting a RAID-5 array.
If I configure the card to power down the drives in the raid array after a
period of idleness, the next time my server attempts to access the logical
device I get:
Oct 19 04:03:03 charon kernel: aacraid: Host adapter abort request.
aacraid: Outstanding commands on (0,0,0,0):

hang ?

at which point the drive is now effectively offline :/
I tried upping the timeout:
root@charon:/etc/udev/rules.d# cat 99-aacraid.rules
SUBSYSTEM=="block", ACTION=="add", ENV{ID_VENDOR}=="Adaptec",
ENV{ID_MODEL}=="Shared", RUN+="/bin/sh -c 'echo 135 >
/sys/block/%k/device/timeout'"
but that didn't appear to stop the problem occurring (and the kernel wasn't
over happy about a >120s timeout).
Any help much appreciated.
