Specifying Different Densities for a Tape Drive
By default, the drive writes at its “preferred” density, which is usually the highest density the tape drive supports. If you do not specify a tape device, the command writes to drive number 0 at the default density the device supports.
To transport a tape to a system whose tape drive supports only a certain density, specify a device name that writes at the desired density. The following table describes how to specify different densities for a tape drive.
Table 29–4 Specifying Different Densities for a Tape Drive|
Drive, Density, and Rewind Value |
Use This Option |
|---|---|
|
First drive, low density, rewind |
/dev/rmt/0l |
|
First drive, low density, no rewind |
/dev/rmt/0ln |
|
Second drive, medium density, rewind |
/dev/rmt/1m |
|
Second drive, medium density, no rewind |
/dev/rmt/1mn |
The additional density values are shown in Backup Device Names.
