Hi all,
here's a topic I'd like to discuss at LSF/MM:
SCSI error handling update to handle I_T Nexus loss.
The current error handler still uses a 'target reset' (or, rather,
bus reset) strategy, although the respective TMF has been obsoleted
since SAM-3. SAM-5 defines an I_T nexus loss event instead, which so
far has only been implemented in libsas.
There has been some discussions on the mailing list, but so far
there hasn't been any conclusion.
So I would like to discuss a possible implementation of a I_T Nexus
loss strategy and how to keep compability with SAM-2 targets.
Cheers,
Hannes
