Table 4-1 Results of Density Selection
If . . . Then . . .
The Density Select button is not
used,
The indicators show the actual density
when the tape is reading and writing. The
indicators are on steady and Density
Override is off.
The Density Select button is
used, and the actual tape
density is the same as the
density selected,
The actual density and the Density
Override indicator lights. For example, if
the actual tape density is 10.0 GB and the
selected tape density is 10.0 GB, then the
indicator next to 10.0 lights.
The Density Select button is
used, and if the actual tape
density differs from the density
selected,
1. The indicator with the actual density
is on steady.
2. The indicator with the selected
density blinks.
3. Density Override indicator lights
steady. For example, if the actual
tape density is 10.0 GB, and the
selected density is 6.0 GB, then the
10.0 indicator lights steady, the 6.0
indicator blinks, and Density
Override indicator lights steady.
To select density over the SCSI bus:
1. Do a SCSI MODE SELCT with the desired density.
2. Write data to the tape from BOT.
