Step 14. Go to the next section, “Verifying the Local Recovery Configuration”.
Verifying the Local Recovery Configuration
To verify that eachconfigured primary ELAN interface is assigned one or
more corresponding secondary ELAN interfaces, follow the steps below
for each ELAN interface you want to verify.
Step 1. Check the log files by typing this command:
more /var/opt/hatmmon/log/*hatmmon.log*
Each primary ELAN interface has a log file that lists all EMS HA-ATM
events recorded by the monitor for that interface. The files are named as
follows:
/var/opt/hatmmon/log/ primary_ELAN_interface_name _hatmmon.log
Step 2. Verify the following things:
• That the messages Starting the monitoring and Configuration
is OK appear for each ELAN interface.
• That the primary ELAN interfaces and all secondary interfaces
appear in the first status message in the log.
• That the secondary ELAN interfaces appear in the order you want
them to be used for local recovery.
• That the status of the primary ELAN interface is “UP.”
• That the primary ELAN interface’s state is “Current” and each
secondary interface’s state is “Backup.”
• That hatmmon is running on the system, by using this command:
ps -ef | grep resource_name
The output should show the following:
/opt/hatmmon/sbin/hatmmon resource_name
Step 3. From another system that is on the same ELAN as the one you are
verifying, open a connection to the primary ELAN interface by using this
command:
telnet IP_address_of _primary_LEC
