Subject: arcmsr: abort device command message weirdness (LUN mismatch)
Date: Sun, 11 Jun 2017 15:40:02 -0400 [thread overview]
Message-ID: <20170611154002.02c0dabb@Vantage.cJ> (raw)
Hi Ching,
Context: when a drive finally failed in my JBOD array, I discovered that
the whole ARC1880X controller would timeout, disabling access to any drive,
which is kind of sad.
I've performed a firmware upgrade and added back the failing drive to see
what happens with a newer device firmware (to be continued).
While doing "cat /dev/${FAILING_DRIVE}", at some point the command fails
(as expected) and while looking at the system logs, I observed that there
were reports of 2 abort sequences initiated then completed, but the
completion message mentions a LUN that is not the one of the failing drive,
which is curious.
