Are the unconfigured LUNs showing up as if they were configured? Most disk/RAID arrays made in the last few years can configure whether they report back as SCSI-2 or SCSI-3. It would be best if you could cha= nge the device to report as SCSI-3. Even some SCSI disk drives are capable of reporting back as SCSI-2 or SCSI-3. -- Patrick Mansfield - To unsubscribe from this list: send the line "unsubscribe linux-scsi" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
