When IP Local Recovery is enabled and the IP resource fails its deepcheck (a periodic extensive check of the IP resource), then SIOS Protection Suite will do the following:
- First, SIOS Protection Suite will attempt to bring the IP address back in service on the current network interface.
- If that fails, SIOS Protection Suite will check the resource instance to determine if there is a backup interface available. If so, it will then attempt to move the IP address to the backup interface.
- If all local recovery attempts fail, SIOS Protection Suite will perform a failover of the IP address and all dependent resources to a backup server.
Even if you do not have a backup adapter, you can enable Local Recovery so that SIOS Protection Suite will retry the primary network interface before initiating failover to a backup server.
