Verifying Connectivity to the Fibre Channel Arbitrated Loop
Verify that the storage subsystem and the host servers are properly connected to the
Fibre Channel Arbitrated Loop.
Storage Subsystem Connectivity to the Loop
Enter the CLI command
show this_controller to ensure that the storage
controller is connected to the loop. If the port 1 topology is in an offline state, refer
to the HSG80 documentation for more information.
The port 1 topology should be LOOP_HARD and indicate that the port state is Loop
Up or Standby. If one storage controller indicates a Loop Up state, the other storage
controller will be in a Standby mode.
Host Server Connectivity to the Loop
To verify that the Microsoft operating system servers are connected to the loop, enter
the CLI command
show connection. The output of this command shows status
information about present and previous connections to the loop. The Unit Address
column refers to the Arbitrated Loop Physical Address. The Status column indicates
the port is online to the other storage controller.
It is recommended that you rename the connection-name field to the computer name
of the server. This action facilitates the ability to discern loop connections.
