Configuring for the DEC/Compaq Unix

Environment

Finding Existing SCSI Controllers and Devices

SCSI ID #7 is almost always dedicated to the SCSI controller. Never configure your target device for

ID 7 unless you are absolutely sure that the controller is not addressed for ID 7.

Configuring Digital UNIX Version 4.0 and later/Compaq Tru64

Unix 5.x

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

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 com-

mand 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.
