Initial Monitor Configuration
Unlike the other EMS Hardware Monitors, the FC-AL hub monitor requires some initial configuration before
it will function. Because a FC-AL hub is not part of the host's configuration, the host cannot detect any hubs
during startup. You must tell the hub monitor what hubs you want it to monitor. This is done by defining two
settings in the hub monitor configuration file, HUB_COUNT and HUB_X_IP_ADDRESS.
Configuring the FC-AL Monitor Configuration File
To configure the FC-AL monitor configuration file complete the following steps:
Step 1. Determine which hubs you want the monitor to be responsible for. Record the IP address for each of
these hubs.
Step 2. Open file /var/stm/config/tools/monitor/dm_fc_hub.cfg in an ASCII text editor.
Step 3. Add the following line to the file:
HUB_COUNT n
Replace "n" with the value that reflects the number of hubs for which the monitor will be
responsible. For example, the following line would monitor 5 hubs:
HUB_COUNT 5
Step 4. Add the following line to file:
HUB_ X _IP_ADDRESS nn.nn.nnn.nnn
Change the placeholder "X" to the number 1, and replace the "nn" fields with the IP address of the
hub that will be designated as hub 1.
The completed line will look similar to the following:
HUB_1_IP_ADDRESS 15.43.214.101
Step 5. If multiple hubs will be monitored, replicate the line from step 4 for each hub, changing the hub
number and IP Address for each. When you are done, the number of lines should equal the number
defined in the HUB_COUNT setting. For example, the following lines would configure the monitor for
three hubs:
HUB_COUNT 3
HUB_1_IP_ADDRESS 15.43.214.101
HUB_2_IP_ADDRESS 15.43.214.171
HUB_3_IP_ADDRESS 15.43.214.184
Step 6. Save the file.
Step 7. To invoke the changes made to the hub configuration file, you must use the Enable Monitoring
option of the Hardware Monitoring Request Manager, even if monitoring is already enabled. The
Enable Monitoring option runs the startup client, which reads the contents of the configuration file
and starts the hub monitor to begin monitoring of the FC-AL hubs. See "Enabling Hardware Event
Monitoring" on page 42 for more information.
There are other settings in the configuration file that can be changed to customize the operation of the FC-AL
hub monitor. These settings are defined in Chapter 5, "Hardware Monitor Configuration Files."
