The device you are trying to access is a LUNZ. Dec 13 09:54:08 arc2 kernel: Vendor: DGC Model: **LUNZ** Rev: 0223 Dec 13 09:54:08 arc2 kernel: Type: Direct- Access ANSI SCSI revision: 04 Dec 13 09:54:08 arc2 kernel: Vendor: DGC Model: **LUNZ** Rev: 0223
This is a device that is used for in band communications with the array. You need to add LUNs to the storage group assigned to your host then rescan the SCSI bus to pick up the new LUN. After point you will have a device that you can write to.

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 [email protected].
