5.3.2 Installing an RA7000 or ESA10000 (SCSI) and a Windows NT Cluster

with Y-Cables.

To establish two individual SCSI busses between clustered Windows NT host servers and

a RAID subsystem, where one bus exists, reference Figure 5-2 and follow these steps:

1. Install the Host Bus Adapter in the servers.

2. Remove the link cable interconnecting both HSZ70 RAID controllers in the storage

subsystem.

3. Move one of the existing VHDCI cables from the bottom controller to the top

controller. Both connectors on the bottom controller should now be unused.

4. Attach Y-cables to each of the new host bus adapters, one new adapter in each server.

5. Attach SCSI terminators to one end of each Y-cable.

6. Attach the (compatible) end of the .2M adapter cable (BN38E-0B) to the available

end of the Y-cable of one server, and extend it to the bottom controller using the 5

meter VHDCI cable (BN37A-05)

7. Attach the VHDCI/HD68 5 meter cable between the remaining Y-cable and the

bottom controller.

8. Reboot the host servers.

The Secure Path solution is now properly prepared, cabled and terminated.
