configuring for Digital UNIX 4.x

1Add the following entry to your /etc/ddr.dbase file:

SCSIDEVICE Type = tape

Name = "BNCHMARK" "DLT1"

2Set the following parameters in the file:

PARAMETERS: MaxTransferSize = 0xffffff ReadyTimeSeconds = 0x2d InquiryLength = 0x20

DENSITY: DensityNumber = 0 OneFileMarkOnClose = yes DensityCode = 0x00 Blocking = 0 CompressionCode = 0x0 Buffered = 0x1

DENSITY: DensityNumber = 1 OneFileMarkOnClose = yes DensityCode = 0x00 Blocking = 0 CompressionCode = 0x1 Buffered = 0x1

3Rebuild the kernel by running /sbin/ddr_config_c, then reboot the system with the tape drive attached. The device files for the DLT1 drive will be generated in /dev/rmt when you reboot.

4The names of the device files can be interpreted as follows:

[n]rmtX D

where:

Code Meaning

n No rewind

XInstance number assigned to the drive by the operating system (0 is the first, 1 is the second, and so on)

hCompression on (high density) l Compression off (low density)

For example, /dev/rmt/nrmt0h is a device file for the first device, which is a high-density, no-rewind device.

Once the device files have been created, you should confirm that your new tape drive is working properly. See Verifying Installation.
