DENSITY:

#

DensityNumber=1

DensityCode=default

CompressionCode=0x1

Buffered=0x1

Save the file. Then run the following command:

ddr_config-c

ddr_config takes the default input file, ddr.dbase, and builds a new device database. This command takes effect immediately without having to rebuild the kernel.

Note: ddr.dbase is a Unix shell script and is not written in C. This means # is used to signify a comment, not /* and */ or //, as used in C. Make sure any comments included in this file are preceded with the # character.

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-3 Tape Drive to Sun Sparc and

 

 

Intel systems.

 

To properly attach SCSI devices to hosts it is necessary to ensure that each

devices installed.
