Hello Or,
The later patches in the srp-ha patch series avoided such behavior by
checking whether the connection between SRP initiator and target is
unique, and by removing duplicate SCSI hosts for which the transport
layer failed. Unfortunately these patches are still under review.
Unless someone can come up with a better solution I will post a patch
one of the next days that makes ib_srp again fail all commands after
host removal started. That will avoid spending a long time doing error
recovery.
Also, you might have noticed that Hannes Reinecke reported a few days
ago that the SCSI error handler may need a lot of time for other
transport types - this behavior is not SRP specific.
Bart.
