Cable Labeling Example
Cable Label
Description
AI-1
Active controller, Internal interface, first controller pair
AX-1
Active controller, External interface, first controller pair
BI-1
Backup controller, Internal interface, first controller pair
BX-1
Backup controller, External interface, first controller pair
More complex configurations would use more than one cable of each type.
Following our example, you would increment the sequence number for each
controller pair.
Connecting the Cables
Cable connection is based on the OSCRO configuration selected during the
planning process.
Single-Channel Configuration
For a single controller-pair configuration, connect the cable from the external
ports of the SMART-2 controllers to the ProLiant Storage System
connectors, connecting the active controller to the primary port. In a tower
system, this is the top port; in a rack-mount, it is the left port as you face the
back of the system.
Dual-Channel Configuration
To implement a dual-channel OSCRO configuration, perform the following
steps:
1.
Shut down Windows NT, and turn off the power to the server.
