Configuring for a DDS T
ape Drive
This section contains instructions for conguring a new DDS driv
e on HP-UX.
The DDS (\Digital Data Storage") T
ape Drive is a sequen
tial-access,
read-write device using removable DDS cassettes. Although DDS driv
es
are similar to DAT players in the audio industry
, the cassettes are
not
interchangeable. There are two ma jor dierences:
1. Audio cassette tap es transfer data in streaming mo de. That is, they are
left in motion for p erio ds of min
utes. Tap es used for data are con
tinually
starting, stopping and repositioning, whic
h is stressful to the tap e. DDS
tap es are made rugged enough to stand this kind of treatmen
t. Audio tap es
are not exp ected to p erform this w
ell, and as a result fail very quickly in a
data environment.
2. DDS cassettes havea much tighter case dimension sp ecication than DAT
cassettes. As a result, DAT cassettes can get stuck in a DDS drive, requiring
the drive to b e disassembled. For this reason, only Hewlett-Packard
supported or prop erly certied DDS tape cartridges should b e used. Use of
DAT tap es intended for audio use could void your warranty.
Caution
Do not attempt to extricate a DAT cassette which is stuck
in a DDS drive. You may damage the drive. Have the drive
disassembled by someone qualied to do so.
