Fibre Channel Arbitrated Loop Hub Monitor
Adding or Removing an FC-AL Hub
Adding or removing a hub from the monitor configuration involves changing the same configuration file settings described in the preceding procedure, HUB_COUNT and HUB_X_IP_ADDRESS.
Changing the FC-AL Hub Monitoring Configuration
To change the FC
Step 1. Determine the IP address for each hub your are adding or deleting.
Step 2. Open file /var/stm/config/tools/monitor/dm_fc_hub.cfg in an ASCII text editor.
Step 3. Locate the following line in the file and change value “n” to reflect the new number of hubs to be monitored:
HUB_COUNT n
Step 4. If you are adding a hub, add the following line to file:
HUB_X_IP_ADDRESS nn.nn.nnn.nnn
Change the placeholder “X” to the number you want assigned to the hub (typically the next sequential number available), and replace the “nn” fields with the IP address of the hub.
The completed line will look similar to the following:
HUB_5_IP_ADDRESS 15.43.214.101
Repeat this step for each hub you are adding.
Step 5. If you are removing a hub, locate the HUB_X_IP_ADDRESS line for the hub to be removed and delete it from the file. If you deleting multiple hubs, delete the line for each one.
Step 6. Save the file.
Step 7. To invoke the changes immediately, run the Hardware Monitoring Request Manager and select the (E)nable Monitoring option. This option runs the startup client, which will cause the changes to the hub monitoring to take effect immediately. See “Enabling Hardware Event Monitoring” on page 35 for more information.
Alternatively you can do nothing and the changes will be made at the next hub polling interval when the monitor recognizes the changes and launches the startup client to invoke them
