Figure 3-1. Recommended Single Expansion Shelf Installation - Compaq StorageWorks RAID Array 3000 Controller Shelf User Manual

The target SCSI bus addresses of the drives in the device expansion shelves
(shown on each storage device in Figures 3-1 through 3-4) are controlled by a
switch on the side of the personality I/O module in each expansion shelf. In a
single expansion shelf configuration, the IDs are 0-5. In a double expansion
shelf configuration, the IDs in both expansion shelves are also 0-5 because
each shelf is connected to a separate device I/O bus from the controller.
In a three and four-shelf configuration (Figures 3-3 and 3-4, respectively), the
second expansion shelf on each device I/O bus is connected to the first via a
Trilink adapter and must be set to 8-13.
