Use File Manager to open the file /etc/ddr.dbase and create an entry as

follows:

SCSIDEVICE

Type=tape

Name="CERTANCE""ULTRIUM 2"

PARAMETERS:

TypeSubClass=tk

TagQueueDepth=0

MaxTransferSize=0x0ffffff#(16MB-1)

ReadyTimeSeconds=180#seconds

CMD_PreventAllow=supported

CMD_ExtReserveRelease=supported

BlockSize=0

PwrMgmt_capable=0

DENSITY:

DensityNumber=0,2,3,4,5,6,7

DensityCode=default

CompressionCode=0x0

Buffered=0x1

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.
