Apply Failover Settings in the PA Administrative Interface
If you are on the primary appliance, you will see Failover page sections indicating Failover :: Primary Site Instance. If you are on the backup appliance, you will only see Failover page sections indicating Failover :: Backup Site Instance. The Failover :: Backup Settings section refers to settings enabled only when the site instance you are on is the backup site instance.
On the primary appliance’s Failover page, the top of the page displays the address and status of the host/primary site and the peer/backup site, as well as the date and time of the last status check. Select Status History to expand or collapse a table of status events that have occurred.
From the primary site's Failover page, you may change the backup appliance settings, manually force a data sync, force a failover for planned maintenance or a known failover event, break the failover relationship, and select the failover shared IP address.
From Failover :: Site Instance Status you first see text confirming that you are either on the primary or backup site instance for your host site. You have access to three command buttons on this page: Sync Now, Become Primary/Backup, and Break Failover Relationships.
If you want to synchronize data from the peer appliance prior to swapping roles, select the checkbox next to the Become Primary or Become Backup button. If this option is selected, all users on the existing primary appliance will be disconnected during the data sync, and no other operations will be available until the swap is complete.
On the primary site instance, you also have the option to become the backup even if the peer appliance cannot be contacted. If this option is unchecked, failover is canceled if both appliances cannot be kept in sync in terms of their failover roles (one primary and one backup).
For example, if you know the current backup appliance is online but cannot be reached by the primary due to a network connection issue, you may wish to check this option to make the primary the backup before the network connection is restored. In this example, you would also need to access the current backup and make it the primary.
From Failover :: Primary Site Instance Configuration, control the shared IP address the site instance uses in the event of a failover by selecting the checkbox for the failover IP address. If you change the relationship between the sites, the checked IP addresses will disable when a primary site becomes a backup, and will enable when a backup becomes a primary site. You should manually mirror the setting on the peer site, as the setting is not shared. Select Save Changes when finished.
When on the primary site instance, select Backup Settings > to expand or collapse the page displaying the configuration fields.
From Failover :: Backup Settings, configure backup settings for the primary and backup site instances. The settings you configure here are enabled only when the site instance you are configuring is in a backup role.
Backup Settings allows you precise control over backup operations. Enable or disable site backups. You can control the timing details of the Automatic Data-Sync Interval, set bandwidth parameters for data-sync, quickly enable or disable automatic failover, and set how long the primary site must be unreachable before failing over. You also may enter IP addresses for the backup site to check to determine whether the backup's inability to reach the primary is because the primary is offline or the backup has lost its network connection.
