Resource Hierarchies - SIOS

Server Properties
setting "Switch Over Resources" indicates that resources will be brought in service on a
backup server in the cluster. The setting "Do not Switch Over Resources" indicates that
resources will not be brought in service on another server in the cluster.
• Server Name. Automatic failover capabilities from the local server to other servers in the
cluster may be configured here. All servers in the cluster should be operational (i.e. at least
one SPS comm path must be active) as inactive servers are not listed. The name of each
active server in the cluster is listed, excluding the local server. For each server, two types of
failover capabilities are configurable. By default, all failover capabilities are enabled.
• Disable Resource Failover- Select the remote server(s) to be disqualified as a
backup server for any failed resource hierarchy on the local server. When disabled, the
designated server is disqualified as a failover site if a local resource fails. Unselect to
re-enable automatic failover capabilities.
• Disable System Failover- Select the remote server(s) to be disqualified as a backup
server for a complete failure of the local server. When disabled, the designated server
is disqualified as a failover site if the local server completely fails. Unselect to re-enable
automatic failover capabilities.
Note: If all remote servers are disabled for resource failovers, then the failed resource will be marked
as "Failed" and no additional quick check or deep check monitoring will be performed for the failed
resource. However, the failed resource as well as other dependent resources in the hierarchy will not
be removed from service and no failover will be attempted.
