Using Your Digital Data Storage (DDS) Tape Drive

Operating the DDS Tape Drive

4Enter the following command line to receive a file listing of the data cassette:

tar -tvf /dev/rmt/3m

To use the data compression mode, substitute /dev/rmt/3hc for /dev/rmt/3m.

Further Command Information

The man utility looks up man pages on the system.

You may also communicate with the tape drive with the cpio, ftio, mt, and fbackup commands. For more information on these commands, enter the following in a terminal window:

Media Interchangeability Restrictions

If you interchange media between DDS-format tape drives, the following two restrictions apply to the media:

•Data cassettes with compressed data can only be read by tape drives which have data compression capabilities, such as the tape drive (part number C1504-67201) found in Kit A2275A #AHS. This includes data cassettes that contain both com- pressed and noncompressed data.

•Use 90-meter data cassettes only in the 3.5-inch form factor DDS-format tape drives found in Kit A2274A #AHS (part number C1503-67201) and Kit A2275A #AHS (part number C1504-67201). The full height (5 1/4-in) DDS-format tape drives cannot read or write to 90-meter data cassettes.
