Meaning and Comments
Tape drive The 3 radio button refers to SCSI ID 3, and 4 refers to SCSI
ID 4. If you have a single tape drive in your Isis system, the tape
drive will be ID 3. If there are two tape drives in an Isis system,
the upper drive will be ID 3 and the lower drive will be ID 4.
Switch
between
drives You have two mutually exclusive choices:
• Automatically (<5%): If this radio button is darkened,
Isis will switch to the other drive when the current target
drive is 95% full.
• Manually: You force Isis to make the switch when you
click the Now! button. The switch occurs regardless how
full the current destination drive is.
Reset Drive In addition to rewinding the tape to its physical beginning, Reset
Drive retensions the tape, checks for available free space, and
prepares it for reading or writing at the compression ratio
specified via the tape’s utilities.

specifying the enabling or disabling of temporary files. You also
use this dialog box to perform tape copying operations. See
