To install the tape backup device, refer to the documentation shipped with the tape device.

To connect the filer to a tape device, perform the following steps:

1.Ensure that the filer is shut down, power is switched off, and the power cords are disconnected from AC power.

If it is not, execute the halt command, then turn off the power on the power supply.

If the filer has two power supplies, turn off both power supplies.

2.Set the SCSI ID on the tape backup device

Refer to the documentation for the tape backup device.

3.If you have a robotic loader on the tape backup device, set its SCSI ID also.

4.Turn off the power on the tape backup device.
