Troubleshooting Expand-Over-ServerNet Line-Handler
Processes and Lines
For general information about Expand-Over-ServerNet lines and line-handler
processes, refer to Section 1, ServerNet Cluster Description or the Expand
Configuration and Management Manual. The Expand-over-ServerNet line-handler
processes are responsible for managing security-related messages and forwarding
packets outside the ServerNet cluster. If you suspect a problem with an Expand-over-
ServerNet line-handler process or line:
1. Verify the status of the line-handler processes by doing one of the following
•
Run the guided procedure for configuring a ServerNet node (Configure
ServerNet Node) to display the ServerNet Cluster Connection Status dialog
box. This dialog box indicates whether or not line-handler processes are
configured between the local node and remote nodes and shows the line
states. For information about running the guided procedure, refer to Section 3,
Installing and Configuring a ServerNet Cluster.
•
At an SCF prompt, type:
-> STATUS DEVICE $ZZWAN.*
2. If the line-handler processes are in the STOPPED state, you can start them using
the SCF START DEVICE command. For example:
-> START DEVICE $ZZWAN.#SC004
3. If the line-handler processes need to be configured, do one of the following:
•
Configure line-handler processes using the guided procedure for configuring a
ServerNet node. For more information, see Section 3, Installing and
Configuring a ServerNet Cluster.
•
Configure the line-handler processes manually using SCF. See the Expand
Configuration and Management Manual.
4. Verify the status of the Expand-over-ServerNet lines by doing one of the following:
•
Using the TSM Service Application, click a Remote Node resource to select it,
and check the Expand attributes in the details pane. See Figure 7-7.
•
At an SCF prompt, type:
-> STATUS LINE $SC004, DETAIL
-> STATUS PATH $SC004, DETAIL
