Lee, It would appear that the guilty party was:
node.conn[0].timeo.noop_out_interval = 5 node.conn[0].timeo.noop_out_timeout = 5 I changed both of these to 0 for the tape device and the problem went away. Please note that the README.gz for open-scsi doesn't actually say that this is what you need to do to disable the NOP-out polling, so could I suggest that this be stated explicitly. I must admit that I find it hard to imagine that an iSCSI target would reply to a NOP-out while it was processing a command such as a tape fsf or even tape erase (whose timeout is 6 * the long-timeout of 4 hours). Should perhaps the NOP-out polling be suspended while a command is being processed? Or alternatively maybe the NOP-out polling be completely disabled by default with something in the README.gz file that explains WHEN you might want it and how to enable it. It's certainly clear that (at least) the MS iSCSI initiator doesn't send NOP-out polls.
