52 LTO-2 Half-Height Tape Drive User’s Guide
To enable the tape driver to turn on data compression when writing data
to tape use the
.c. option.
For commands that use density and tape size settings, the tape density is
124,000 bpi and the tape length is 1800 feet. For commands that use a
blocking factor, we recommend a blocking factor of 64 as a minimum (128
is recommended).

Use the following for attaching the LTO-2 Half-Height Tape Drive to Sun
Sparc and Intel systems.
Finding Current
SCSI Controllers
and Targets
6
To properly attach SCSI devices to hosts it is necessary to ensure that each
target device has a unique SCSI address. The commands .
modinfo.
and .
dmesg. can be used to find the SCSI controllers in use and the SCSI
target devices installed.
For example, the command
.dmesg | egrep .target. | sort | uniq. can find all
SCSI controllers and SCSI targets. The output may look similar to:
sd32 at ithps0: target2 lun0
sd34 at ithps0: target4 lun0
st21 at ithps1: target0 lun0
st22 at ithps1: target1 lun0
In this case, the LTO-2 Half-Height Tape Drive can be set for SCSI ID
address 2 through 6 and attached to controller ithps1 (this particular
controller also supports SCSI addresses 8 through 15).
Types of
Controllers

You may be able to view the main pages of three types of SCSI controllers
for Sun Sparc systems:
