Installing a Super DLTtape or DLTtape Drive into a Sun Solaris 2.X System (versions 2.5 and lower)
2.1 Before You Begin
Before you install the tape drive, follow these steps:
1. If you have a DLT 2000, DLT 2500, or DLT 2700 product, make sure it is using
version V10 (or higher) controller firmware.
Note: The DLT 2000XT, DLT 2500XT, DLT 2700XT, DLT 4000,
DLT 7000, DLT 8000, SDLT 220, and SDLT 320 tape drives
do not have a firmware revision restriction.
2. Make sure that the hardware has the appropriate SCSI interf a ce for the tape drive. If
you have a SCSI single-ended (SE) tape drive, you need a SCSI SE interface; if you
have a SCSI low-voltage differential (LVD) or high-voltage differential (HVD) tape
drive, you need a SCSI LVD or HVD interface.
3. Obtain the appropriate manual for your tape drive as listed in Table 1. These manuals
provide detailed hardware installation instructions, including switch and jumper
settings and information about SCSI bus termination.
Note: To view these manuals online, go to: http://www.quantum.com/AM/

2.2 Installing the Tape Drive
To install the tape drive, follow these steps:
1. Power down your workstation or server and disconnect the AC power from the
system.
2. Follow instructions in your product manual to install the tape drive and set
the SCSI ID.
2.3 Editing the st.conf File
1. Power on the hardware and execute a probe-scsi command. The system should
indicate that the tape drive is attached. You can then verify the tape drive’s SCSI ID.
2. Boot the system and log in as root.
3. Change the directory to /kernel/drv.
The st.conf file is located in this directory and is used by Sun’s st (SCSI tape)
driver. The st man page on Solaris has more information about the st driver and the
st.conf file.
CAUTION
Back up your st.conf file before making any modifications.
Only someone who is familiar with rebuilding the Solaris kernel
should make changes.
4. Edit the st.conf file by adding the following line before the first occurrence of
name= in the file:
tape-config-list = “<DLTtape tape unit>”,
“<DLTtape reference name>”, “<DLTtape data
>”;

Installing a Super DLTtape or DLTtape Drive into a Sun Solaris 2.X System (versions 2.5 and lower)
2.4 Verify i ng the Installati on
After editing the st.conf file, fol low these steps:
1. Load a data cartridge into the tape drive, following the instructions in your manual.
2. Change the directory to /.
3. Enter shutdown -i0 -g0 to shut down the system.
4. Enter boot -rv to reboot the system.
The r switch in the boot command recompiles the kernel and creates a special device
file the system uses for communicating with the tape drive.
Note: The device files created for the tape drive are located in the /dev/rmt/
path and are discussed in “Device File Assignments” on page 10.
The v switch enables verbose mode display during system bootup. With verbose
mode, the system indicates that the tape drive is attached by displaying the
<DLTtape reference name> string you selected (see Ta ble 2 on page 7).
Note: If you did not edit the st.conf file correctly, the system displays the
following during boot -rv:
<Vendor ‘vendor’ Product ‘tape drive’>
5. To verify that the tape drive has been installed and that a data cartridge is loaded,
mt -f /dev/rmt/0 status.
enter
On Solaris configurations 2.5.1 and below, mt responds with a display similar to the
following:
Other tape drive
sense key(0x6)= Unit Attentionresidual= 0 retries= 0
file no= 0 block no= 0
Installation is complete.

2.4.1 Device File A ssignments
When you issue a boot -rv command, Solaris recompiles the kernel and creates a special
device file used for communicating with the tape drive . This fil e, loc ated in the /dev/rmt
path, has the following form:
[0-127][l,m,h,c,u][b][n]
Note: This file name may not include all possible values.
Table 4 defines the values of this file.
Table 4. Device File Values and Definitions
Device File Value Definition
[0-127] The target tape drive designation Solaris assigns during boot -rv
(see “Target Tape Drive Designations” on page 11).
[l,m,h,c,u] The tape density the tape drive uses during write operations. The first four letters
map to the four density assignments in the <DLTtape data> line in the st.conf
file. If these letters are not in the device file, the tape drive uses the default density
designated by the last parameter in the <DLTtape data> line in the st.conf
file. This is the highest density with compression for this configuration.
The following list defines each letter:
• l - low density
• m - medium density
• h - high density
• c - compressed (same density as u)
• u - ultra (same density as c).
[b] The BSD behavior. See mtio man page for more information.
[n] The rewind behavior. The tape drive does not rewind the tape when the command
is comple te.
10 July 2003 6464107-01 Rev A
Installing a Super DLTtape or DLTtape Drive into a Sun Solaris 2.X System (versions 2.5 and lower)
For example, listing the device files in /dev/rmt for the first tape drive assigned by
Solaris may look similar to the following:
ls /dev/rmt/0*
/dev/rmt/0 /dev/rmt/0cbn /dev/rmt/0hn /dev/rmt/0m /dev/rmt/0u
/dev/rmt/0b /dev/rmt/0cn /dev/rmt/01 /dev/rmt/0mb /dev/rmt/0ub
/dev/rmt/0bn /dev/rmt/0h /dev/rmt/01b /dev/rmt/0mbn /dev/rmt/0ubn
/dev/rmt/0c /dev/rmt/0hb /dev/rmt/01bn /dev/rmt/0mn /dev/rmt/0un
/dev/rmt/0cb /dev/rmt/0hbn /dev/rmt/01n /dev/rmt/0n
2.4.2 Tar get Tape Drive Designations
The target drive designations Solaris assigns may take on values higher than those
established in the /dev/rmt/ path. This is not a problem; however, during a boot -rv,
Solaris does not remove the tape device files for tape drives that are no longer attached
to the system. As a result, it can become difficult to locate the device file for the
configured tape drive. To minimize this problem, initially delete the tape device files
(rm /dev/rmt/*). Then either boot the system with a boot -rv or enter the following at
the command line prompt:
drvconfig -i st; tapes
If the DLTtape drive is the only drive on the system, its target assignment should be 0. The
Solaris man pages have more information about drvconfig and tapes.

3. Data Cartridge Compatibility
Table 5 provides information about data cartridge and tape drive compatibility. Use this
matrix when determining data cartridges to use in your tape drive.
Note: The SDLT 220 and SDLT 320 tape drives can read, but not append
data to, DLTtape IV data cartridges that were previously written by a
DLT 4000, DLT 7000, or DLT 8000 tape drive.

4. Using a DLTtape Mini-Library
The Solaris operating system does not support SCSI-2 media changer device commands.
Therefore, you cannot use a DLT 2500, DLT 2500XT, DLT 2700, DLT 2700XT,
DLT 4500, or DLT 4700 in random access mode. You can access the mini-library in
sequential mode only.
For a detailed description of these access modes, refer to the appropriate product manual
for your DLTtape mini-library. See Table 1 on page 5.

10 density code
number
The density the system will use as the default density, assuming that
the four densities—the sixth, seventh, eighth, and ninth parameters
in the <DLTtape data> string—are referenced by the system as 0,
1, 2, and 3, respectively. For example, in a DLT 8000 configuration,
the value of 3 for the tenth parameter selects 0x89 as the default
density code.
a. This dens ity code is invalid and results in the tape drive defaulting to the optimal density for the loaded data cartri dge if you are
using one of the following drives: DLT 2000XT, DLT 2500XT, DLT 2700XT, DLT 4000, DLT 4500 , DLT 4700, or D LT 7000 loaded
