Troubleshooting 7-13 The topology for Port 1 on each array controller should be: I Fabric Up state (not the Standby state) I FABRIC Server Node Connectivity to Fibre Channel Fabric Connection Paths To verify that your servers are connected to all Fibre Channel Fabric paths, open a CLI window and issue the CLI command show connection. The output of this command shows status information about present and previous connections to all Fibre Channel Fabric paths, including connection name, controller, controller port, adapter ID address, status, and unit offset. The status entry indicates the port is Online (connected) or Offline (disconnected). Rename the connection-name field to reflect the configuration of the array controllers (for example, SVR1TOP1 for node 1, top controller, port 1). This will improve your ability to view the Fibre Channel Fabric connections. For further information about controller properties, see "Setting Up and Configuring an MA8000/EMA12000 Storage Subsystem" in Chapter 5, "Installation and Configuration." Verifying Connectivity to a Redundant Fibre Channel Arbitrated Loop Verify that the array controllers and the cluster nodes are properly connected to all paths of the redundant Fibre Channel Arbitrated Loop (FC-AL) as described in this section. Fibre Channel Arbitrated Loop Connectivity Guidelines To ensure that all connections along the FC-AL paths are correct, verify the following: I KGPSA-BC or KGPSA-CB Host Adapters have been installed in the same slot locations across all cluster nodes. I For each host adapter pair installed in the server, verify that the upper (or leftmost) host adapter is connected by Fibre Channel cable to one Storage Hub and that the bottom (or rightmost) host adapter is connected to the second Storage Hub.
