Later sections describe how to install cables to configure an HSZ20, HSZ40, or HSZ50 in a TruCluster Server configuration with two member systems.
9.4.1Preparing BA350, BA356, and UltraSCSI BA356 Storage Shelves for an Externally Terminated TruCluster Server Configuration
You may be using the BA350, BA356, or UltraSCSI BA356 storage shelves in your TruCluster Server configuration as follows:
•A BA350 storage shelf provides access to SCSI devices through an
•A
•An UltraSCSI BA356 storage shelf provides access to UltraSCSI devices through a
The following sections discuss the steps necessary to prepare the individual storage shelves, and then connect two storage shelves together to provide the additional storage.
______________________ Note _______________________
This material has been written with the premise that there are only two member systems in any TruCluster Server configuration using direct connect disks for storage. Using this assumption, and further assuming that the member systems use SCSI IDs 6 and 7, the storage shelf housing disks in the range of SCSI IDs 0 through 6 can only use SCSI IDs 0 through 5.
If there are more than two member systems, additional disk slots will be needed to provide the additional member system SCSI IDs.
9.4.1.1 Preparing a BA350 Storage Shelf for Shared SCSI Usage
To prepare a BA350 storage shelf for usage on a shared SCSI bus, follow these steps:
1.Ensure that the BA350 storage shelf ’s internal termination and jumper is installed (see Section 9.3.1 and Figure
