It looks like the target is not set up correctly or you trying to access the wrong device. Is sdb's module listed as LUNZ? cat /sys/block/sdb/device/model If so then that is not a LUN that has storage backing it. It is some sort of magic administration type of device. You might not have the target setup so the initiator can access the storage correctly. Is there some sort of access list on the target? Does it work with software iscsi? -- You received this message because you are subscribed to the Google Groups "open-iscsi" group. To post to this group, send email to open-iscsi@googlegroups.com.
