A secondary SpectroSERVER is considered to be at one of three different levels of readiness. Readiness depends on server configuration and status. The readiness levels are defined as follows:
The secondary SpectroSERVER is running and is available to take over immediately upon failure of the primary SpectroSERVER because it is already polling. To configure a secondary SpectroSERVER for this level of readiness, add the following line to the .vnmrc file: secondary_polling=yes. This statement causes the standby to commence polling and processing traps whenever it starts, regardless of its connection status with the primary SpectroSERVER.
The secondary SpectroSERVER is running, but the server can take a short time to become fully available. The secondary SpectroSERVER has not been configured to start polling until it loses contact with the primary SpectroSERVER. For example, it has no secondary_polling entry in the .vnmrc file, or the entry is set to no.
If the secondary_polling entry is not in the .vnmrc file or the entry is set to no, the secondary SpectroSERVER does not process traps while in standby mode.
The secondary SpectroSERVER is not running and must be started when there is a failure of the primary SpectroSERVER. In this case, it is irrelevant whether the secondary SpectroSERVER is configured for secondary polling.
