Hi Tony,

Apologies for the delay. This was not forgotten, there were repro attempts 
and discussions happening internally.

Thanks for the info. Just to reiterate, you've reported two issues (though 
this log was showing only 1 of them).

Issue 1 - Tape device never disappears when removed
Issue 2 - When a direct connected tape 1 was replaced with tape 2, tape 2 
          was not discovered.

For Issue-2, please try the attached patch. This may not be the final fix, 
but wanted to check if that would fix the issue for you.

For Issue-1, the behavior was intentional, though that behavior needs 
refinement. These tape drives support something called FC sequence level 
error recovery (added in FCP-2), which can make tape I/Os survive even 
across a short cable pull. This is not a simple retry of the I/O, rather a 
retry done at the FC sequence level that gives the IO a better chance of
revival. In other words, the said patch that caused regression, while 
introduces an incorrect reporting of the state of the device, makes backup 
more resilient.

Now, onto the behavior when device state is reported immediately. What we 
have observed, at least with one tape drive from a major vendor, is that, 
across a device loss and device back case with both the events reported to 
upper layers, the backup operation was getting failed. This is due to a 
REPORT LUNS command being issued during device reappearance reporting 
(fc_remote_port_add -> SCSI scan), which the tape drive was not expecting 
and caused the backup to fail.

I know that some tape drives do not support multiple commands to it at the 
same time, but not sure if that is still the norm these days.

So, perhaps one way to make the behavior better, is to either report the 
disappearing device a bit delayed or have intelligence added in SCSI scan 
to detect ongoing tape IO operations and delay/avoid the REPORT LUNs. 
Former is a more contained (in the LLD) fix.

Regards,
-Arun
