It's not that simple, unfortunately. Some HBAs keep more state than others. We see cases fairly often where a misbehaving target has confused the HBA enough that we can not bring the device back without doing an HBA firmware reset. Despite I/O completing successfully on other targets connected to the same HBA. So at some point we do need to give up and escalate to a full HBA reset. We would just like to defer that hammer until we have run out of other options. -- Martin K.
