The 3 common issues which casue problemw with SCSI tapes: Incorrect major/minor device numbers (see section on HPDD in the Maintenance Procedures section of the Operating System Guide). Incorrect LUN (logical unit number). This seems to work best if LUN > 3. Incorrect DMA channel. Verify that the hardware DMA (should be 5 or 6) matches the value in software. This value is stored in /etc/conf/cf.d/mdevice on the line that begins with "TAPE" in the far left column. The value is in the far right column. This value sometimes is delivered as "-1". If it is incorrect, set it to match hardware and rebuild the kernel. .... support
