5.3.3 Installing an RA7000 or ESA10000 (SCSI) and a Windows NT Cluster
with SCSI Hubs.
To establish two individual SCSI busses between clustered Windows NT host servers and
a RAID subsystem, where one bus currently exists, reference Figure 5-3 and follow these
steps:
1. Install the host adapter in the servers.
2. Remove the link cable interconnecting both HSZ70 RAID controllers in the storage
subsystem.
3. Install a VHDCI terminator on the both controllers (one already has a terminator
installed)
4. Attach the (compatible) end of the .2M adapter cable (BN38E-0B) to the host bus
adapters, and extend it to a SCSI hub using the 5 meter VHDCI cable (BN37A-05)
5. Connect the remaining port of the 3 port SCSI hub to the RAID Array controller.
6. Reboot the host servers.
The Secure Path solution is now properly prepared, cabled and terminated.
