aThe maximum length of the BN38C (or BN38D) cable on one SCSI bus segment must not exceed 25 meters.

bThe maximum length of the BN37A cable must not exceed 25 meters.

cThe maximum combined length of these cables must not exceed 25 meters.

dThe maximum length of this cable, or of two cables if two tape drives are daisy-chained, is 3 meters.

8.5 Preparing the TZ885 for Shared SCSI Usage

The TZ885 Digital Linear Tape subsystems combine a cartridge tape drive (TZ88) and an automatic cartridge loader. The TZ885 uses a removable magazine.

The TZ885 uses a five-cartridge (CompacTape IV) minitape library (magazine) with a 200-GB capacity (compressed). It is capable of reading/writing at approximately 10.8 GB per hour.

As with any of the shared SCSI devices, the TZ885 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 preparing the TZ885 in more detail.

8.5.1 Setting the TZ885 SCSI ID

To set the TZ885 SCSI ID from the Operators Control Panel (OCP), follow these steps:

1.Press and hold the Display Mode push button (for about five seconds) until the SCSI ID SEL message is displayed:

SCSI ID SEL SCSI ID 0

2.Press the Select push button until you see the desired SCSI ID number in the display.

3.Press the Display Mode push button again.

4.Issue a bus reset or turn the minilibrary power off and on again to cause the drive to recognize the new SCSI ID.
