Configuring a Shared SCSI Bus for Tape Drive Use

The topics in this section provide information on preparing the various tape devices for use on a shared SCSI bus with the TruCluster Server product.

______________________ Notes ______________________

Section 8.7 and Section 8.8 provide documentation for the TL890/TL891/TL892 MiniLibrary family as sold with the DS-TL891-NE/NG, DS-TL891-NT, DS-TL892-UA, DS-TL890-NE/NG part numbers.

The TL881, with a Compaq 6-3 part number was recently qualified in cluster configurations. The TL891 rackmount base unit has been provided with a Compaq 6-3 part number. The TL881 and TL891 only differ in the type of tape drive they use. They both work with an expansion unit (previously called the DS-TL890-NE) and a new module called the data unit.

Section 8.12 covers the TL881 and TL891 with the common components as sold with the Compaq 6-3 part numbers.

As long as the TL89x MiniLibrary family is being sold with both sets of part numbers, the documentation will retain the documentation for both ways to configure the MiniLibrary.

8.1 Preparing the TZ88 for Shared Bus Usage

Two versions of the TZ88 are supported, the TZ88N-TA tabletop standalone enclosure, and the TZ88N-VA StorageWorks building blocks (SBB) 5.25-inch carrier.

As with any of the shared SCSI devices, the TZ88N-TA and TZ88N-VA 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 TZ88 in more detail.
