Verifying SAN connectivity

Step Description Check

For switch fabric SAN connectivity:

• Log on to the switch management utility and verify that the switch fabric is set up

properly, including zoning.

• From the MSA CLI, enter show this_controller to verify that this MSA array

controller is configured for switch fabric connectivity.

• From the MSA CLI, enter show other_controller to verify that the other MSA

array controller is configured for switch fabric connectivity.

Example display:

CLI>show this_controller

Terminal speed for the CLI is set to 19200.

Host Port_1:

REPORTED PORT_ID 500508B3-00909AA9

PORT_1_TOPOLOGY = F_Port (Switch Fabric Enabled)

For direct connect SAN connectivity:

From the MSA CLI of the newly added controller:

• Enter show this_controller_hard_address to determine if the MSA array

controller is configured for direct connect SAN connectivity.

• Enter set this_controller_hard_address to enable hard addressing on

the array controller.

Example display when hard addressing is disabled:

CLI>show this_controller_hard_address

Hard Addressing is disabled.

Example display of enabling a hard address:

CLI>set this_controller_hard_address enable 10

Hard Addressing is enabled.
