Administration of the OVO Management Server in a Cluster Environment
Switchover Example
588
Switchover Procedure
When a system failure occurs on Node A, the cluster initiates switchover
of the Resource Group ov-server from Node A. The Resource Group is
stopped on Node A and started on Node B. The procedure is conducted as
follows:
1. On Node A:
a. Cluster Manager stops the OVO management server running as
OV application by performing the following action:
/opt/OV/lbin/ovharg -stop ov-server
The ovharg script reads all stop links and executes stop scripts
in the appropriate sequence.
b. Cluster Manager designs the virtual IP and unmounts shared
file systems.
2. On Node B:
a. Cluster Manager assigns the virtual IP and mounts shared file
systems.
b. Cluster Manager starts the OVO management server running as
OV application by performing the following action:
/opt/OV/lbin/ovharg -start ov-server
The ovharg script reads all start links and executes start scripts
in the appropriate sequence.
The Resource Group ov-server is now active on Node B.
