Updating the tape driver
NOTE: DDS-4 and DAT 72 drives are natively supported on HP Alpha Tru64 v5.1B-2 and above.
DAT 160 drives are natively supported on HP Alpha Tru64 V5.1B-3. Steps 1–3 below are only
required for earlier versions of Tru64.
1. Versions of Tru64 before v5.1B-2 only (v5.1B-3 for DAT 160 drives): Modify the SCSI Tape
Density Table in the
/etc/ddr.dbase file to include:
scsi_tape_density[0x48] = "174500_bpi" 174500 0 (DAT160)
scsi_tape_density[0x47] = "163000_bpi" 163000 0 (DAT72)
scsi_tape_density[0x26] = "97000_bpi" 97000 0
2. Versions of Tru64 before v5.1B-2 only (v5.1B-3 for DAT 160 drives): Add the following entry to
your
/etc/ddr.dbase file:
DAT 160 drives:
