Well, haven't yet been able to try the firmware suggestion, but we did
replace the backplane. No change.
I'm not sure the firmware change would do any good either. As it is
now, as long as the SSD drives are attached directly to the LSI
controller (no intermediary backplane), everything works fine -- no
errors.
As soon as the backplane is put in the equation -- and *only* for SSD
devices used as ZIL, we begin seeing the timeout/retries.
Seems like if it were a 1068E firmware issue we'd be seeing the issue
whether or not the backplane is in place... but maybe I'm missing
something.
It's possible that the backplane leads to enough signal degredation
that the setup is now stressing error paths that simply aren't hit
with the direct-connect cabling.
This is the sort of issue that adapter (or device or expander)
firmware changes can mitigate or exacerbate.
