DLTtape Tape Unit Installation IRIX 5.3 and 6.X SGI sytems

This application note is to be used only as a guideline for the titled subject. The user assumes all responsibility for understanding the interrelationships of this information with other affected software or system products. Quantum Corporation provides this information as a service only, and assumes no responsibility for any damages which, could result from the use of this information.

The information in this application note is subject to change without notice and is not to be construed as a commitment by Quantum Corporation. Quantum Corporation assumes no responsibility for any errors that may appear in this document.

NOTE: The information in this document pertains to DLT™2000,DLT™2000XT, DLT™4000, DLT™7000 or DLT™8000 cartridge tape drive or the DLT™2500, DLT™2500XT, DLT™2700, DLT™2700XT, DLT™4500 or DLT™4700 tape mini-library that you are installing. The following section describes the installation and configuration of a DLTtape tape peripheral on the Silicon Graphics system running IRIX release 5.3 or 6.X. The DLTtape controller firmware must be OEM-1. The section following the installation includes information about DLT tape cartridge compatibility and information about IRIX behavior when there are periods of non-use of the DLTtape drive. The last section describes important information regarding the use of an installed DLTtape mini-library.

Installation

SGI system must have the appropriate SCSI interface for DLTtape drive to attach to, i.e., a SCSI singleended DLTtape drive can be attached only to a SCSI single-ended interface. The same is true for SCSI differential attachment. The hardware attachment requires the DLTtape tape peripheral to be attached to the SCSI interface while the system is powered down. After the DLTtape tape peripheral has been attached, you will need to make file modifications and perform certain system operations that allow the DLTtape tape peripheral to be recognized.

Perform the installation as follows:

1. Shut down the SGI system and remove ac power from the system. Install the DLTtape tape peripheral

and connect it to its SCSI controller. Depending on the DLTtape tape peripheral you are installing, refer to one of the following manuals for switch and jumper settings and SCSI bus termination:

• DLT2000/DLT2700 product manual (order number 81-109132)

• DLT2500 owner's manual (order number 81-109374)

• DLT2000XT/DLT2500XT/DLT2700XT product manual (order number 81-109253)

• DLT4000/DLT4500/DLT4700 product manual (order number 81-106336)

• DLT7000 Tape Drive product manual (order number 81-60000)

• DLT8000 Tape Drive product manual (order number 81-60118)

Set the DLTtape SCSI device address to an unassigned ID.

2. Turn power on and boot the system. Log on as root and execute the following UNIX command to verify the DLTtape attachment:

hinv -c tape

Quantum Corporation DLTtape 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 3 DEC DLT2000 DLT2500 or DLT2500XT 3 DEC DLT2500 DLT2700 or DLT2700XT 3 DEC DLT2700 DLT4000 7 Quantum DLT4000 DLT4500 7 Quantum DLT4500 DLT4700 7 Quantum DLT4700 DLT7000 7 Quantum DLT7000 DLT8000 7 Quantum 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.

4. Enter the following command to configure the DLTtape device into the system: /etc/autoconfig

5. Reboot the system.
