Configuring for the DEC/Compaq UNIX Environment
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
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 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.
