8.5 Preparing the TZ887 for Shared SCSI Bus Usage

The TZ887 Digital Linear Tape (DLT) MiniLibrary combines a cartridge tape drive (TZ88) and an automatic cartridge loader. It uses a seven-cartridge (CompacTape IV) removable magazine with a total capacity of nearly 280 GB compressed. It is capable of reading/writing at approximately 10.8 GB per hour.

As with any of the shared SCSI devices, the TZ887 SCSI IDs must be set to ensure that no two SCSI devices on the shared SCSI bus have the same

SCSI ID.

The following sections describe how to prepare the TZ887 in more detail.

8.5.1 Setting the TZ887 SCSI ID

The TZ887 SCSI ID is set with a push-button counter switch on the rear of the unit (see Figure 8–7). Push the button above the counter to increment the address; push the button below the counter to decrement the address until you have the desired SCSI ID selected.
