DLTtapeTM Application Note
_____________________________________________________________________________________________ For a DLTtape device whose SCSI ID is set to 4 and is attached to the system's first host adapter but not system configured, the system response should be similar to the following: Tape drive: unit 4 on SCSI controller 0: unknown 3. If you're operating system is IRIX 5. 3, open the /usr/var/sysgen/master. d/scsi file for editing; for IRIX 6. X, open /var/sysgen/master. d/scsi file for editing. As appropriate for the currently running operating system version, add the following to the table of structures. This will enable DLTtape system recognition: For IRIX 5. 3: /* DLTtape tape drive */ {DECDLT, TPDLT, "<Vendor length>", 7, "<Vendor ID>", "<DLT tape unit>", 0 , 0, {0, 0, 0, 0 }, MTCAN_BSF | MTCAN_BSR | MTCAN_APPEND | MTCAN_SPEOD | MTCAN_CHKRDY | MTCAN_VAR | MTCAN_SETSZ | MTCAN_SILI | MTCAN_SEEK | MTCAN_SYNC | MTCAN_CHTYPEANY, 20, 8*60, 20*60, 5*60, 16384, 64*1024} For IRIX 6. X: /* DLTtape tape drive */ {DECDLT, TPDLT, "<Vendor length>", 7, "<Vendor ID>", "<DLT tape unit>", 0 , 0, {0, 0, 0, 0 }, MTCAN_BSF | MTCAN_BSR | MTCAN_APPEND | MTCAN_SPEOD | MTCAN_CHKRDY | MTCAN_VAR | MTCAN_SETSZ | MTCAN_SILI | MTCAN_SEEK | MTCAN_SYNC | MTCAN_CHTYPEANY, 20, 8*60, 20*60, 5*60, 16384, 64*1024, 0 (u_char *)0} Depending on the DLTtape tape peripheral you are installing, you will need to make substitutions for <Vendor length>, <Vendor ID>, and <DLTtape tape unit> in the above structure. The following table shows the DLT tape product and the corresponding substitution values: DLTtape Tape Product <Vendor length> <Vendor ID> <DLTtape tape unit> DLTtape Tape Product DLT2000 or DLT2000XT DLT2500 or DLT2500XT DLT2700 or DLT2700XT DLT4000 DLT4500 DLT4700 DLT7000 DLT8000 <Vendor length> 3 3 3 7 7 7 7 7 <Vendor ID> DEC DEC DEC Quantum Quantum Quantum Quantum Quantum <DLTtape tape unit> DLT2000 DLT2500 DLT2700 DLT4000 DLT4500 DLT4700 DLT7000 DLT8000
Keep in mind that the Vendor ID entries are case sensitive. Refer to the tpsc_types structure in the /usr/include/sys/tpsc. h file for further information on the above structure entries and to the /usr/include/sys/mtio. h file for further information on the MTCAN flag definitions. Enter the following command to configure the DLTtape device into the system: /etc/autoconfig 5. Reboot the system.

Enter the following command to establish the DLTtape device files: /MAKEDEV 7. Verify the DLTtape device files by entering the following command: ls /dev/rmt For a DLTtape tape peripheral installed with a SCSI ID of 4, the system response should be similar to the following: tps0d4 tps0d4c tps0d4nr tps0d4nrc tps0d4nrns tps0d4nrnsc tps0d4nrnsv tps0d4nrnsvc tps0d4nrs tps0d4nrsc tps0d4nrsv tps0d4nrsvc tps0d4nrv tps0d4nrvc tps0d4ns tps0d4nsc tps0d4nsv tps0d4nsvc tps0d4s tps0d4sc tps0d4stat tps0d4sv tps0d4svc tps0d4v tps0d4vc
8. Enter the following command to verify the installation: mt -t /dev/rmt/tps0d4 status Note: that the device file tps0d4 is for an installed DLT2000 with SCSI ID of 4.
