Procedure 7-3 To perform a server activity switch
Perform this procedure to reverse the primary and standby roles of the main servers in
a redundant 5620 SAM system. Consider the following before you perform a server
activity switch.
• Each client GUI receives notification of a server activity switch.
• During a server activity switch, a main server does not process SNMP traps,
attempt to synchronize NEs, or collect statistics.
• During a server activity switch, auxiliary servers process outstanding requests,
but do not communicate with a main server.
• After a server activity switch, the new primary main server deploys
outstanding configuration changes to NEs, establishes communication with the
auxiliary servers, and synchronizes information with the auxiliary servers.
• A manual activity switch stops and starts the former primary main server.
Server redundancy is unavailable until the former primary main server is fully
initialized as the new standby main server.
1 Log in to the primary main server station as the samadmin user.
2 Open a console window.
3 Enter the following at the CLI prompt:
bash$ install_dir/nms/bin/nmsserver.bash force_restart ↵
where install_dir is the 5620 SAM server installation location, typically /opt/5620sam/server
The server activity switch begins. The primary main server restarts as the standby
main server, and the former standby main server becomes the new primary main
server.
4 Close the console window.
5 Clear alarms, as required. The activity switch alarms must be cleared manually.
6 Verify that the GUI and OSS clients can connect to the new primary main server.
