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.
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).

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.
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.
