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.
		To properly attach SCSI devices to hosts it is necessary to ensure that each
	Finding Current
SCSI Controllers		target device has a unique SCSI address. The commands .modinfo.
and Targets		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).
		You may be able to view the main pages of three types of SCSI controllers

Controllers		for Sun Sparc systems:
