When creating cluster application, it is possible to convert standby node of GLS resource into "Standby" state by setting a value of "StandbyTransition" attribute. If neglecting this configuration, it will not monitor the status of standby node of GLS resource. For reference, see "5.1.4 Monitoring resource status of standby node".
[Changes]
Before modification
GLS resource is set to "Offline" and it does not monitor the standby node of GLS resource state.
After modification
GLS resource is converted as "Standby" status and it monitors the standby node of GLS resource status.
[Notes]
For GS/SURE linkage mode, the virtual interface on standby node side is inactive and its monitoring function stops. Therefore, it cannot monitor the GLS resource on the standby node. Unlike other modes, GS/SURE linkage mode does not require to specify "StandbyTransition" attribute because it does not run the resource monitoring.
When attempting to restore the configuration file for 4.1A10 to the cluster system of version 4.1A20 or later using the backup function of a cluster system, the value "StandbyTransistion" attribute will not be set as the default value. If this configuration is used without any modification, it does not monitor the GLS resource status in standby node. In such case, temporary stop the cluster application and use RMS Wizard to apply the "StandbyTransition" attribute in the configuration file.

If a user abruptly uses ifconfig(1M) command to change the status of configured physical interface up or down, interface state monitoring function recovers this change to the state where it was initially running. For details on interface state monitoring function, refer to "2.3.4 Interface status monitoring feature".
[Changes]
Before modification
It does not recover to the original state.
After modification
Recovers to the original state.
[Notes]
In order to terminate the usage of NIC switching mode or to apply changes to physical interfaces, restart interface status monitoring function of the bundled physical interface using resethanet -s command after deleting or changing the configuration settings. For details on resethanet command, refer to "7.15 resethanet Command".
