If the buses are not labeled, you might need to manually trace the buses
to see which connect to remote locations. You can also use the Hardware Service
Manager to determine which buses go to which expansion units. The packaging
resources that are associated with a Logical Resource panel displays the frame
ID and resource name of the expansion unit that is associated with the bus.
To use the Hardware Service Manager to find the buses that control remote
disk units, perform these steps:
- From the DST Main Menu, select Start a service tool.
- From the Start a Service Tool display, select Hardware service
manager.
- From the Hardware Service Manager menu, select Logical hardware
resources.
- From the Logical Hardware Resources menu, select System bus
resources.
- On the Logical Hardware Resource on System Bus panel, enter option 8 before
each bus to display the associated packaging resources.
- If you need more information to help you find and distinguish the expansion
unit in question, enter option 5 for the System expansion unit
to display other details about the expansion unit.
- Record the remote or local location of the bus.
- Then repeat this procedure for all buses on the system.
