Set Start, Failover, And Failback Modes - Novell NETWARE 6-DOCUMENTATION Manual

Set Start, Failover, and Failback Modes

You can configure the start, failover, and failback of cluster resources to
happen manually or automatically. With the resource Start Mode set to AUTO,
the resource automatically starts on a server when the cluster is first brought
up. If the resource Start Mode is set to MANUAL, you can manually start the
resource on a server when you want, instead of having it automatically start
when servers in the cluster are brought up.
With the resource Failover Mode set to AUTO, the resource automatically
starts on the next server in the Assigned Nodes list in the event of a hardware
or software failure. If the resource Failover Mode is set to MANUAL, you can
intervene after a failure occurs and before the resource is moved to another
node.
With the resource Failback Mode set to DISABLE, the resource does not fail
back to its most preferred node when the most preferred node rejoins the
cluster. If the resource Failback Mode is set to AUTO, the resource
automatically fails back to its most preferred node when the most preferred
node rejoins the cluster. Set the resource Failback Mode to MANUAL to
prevent the resource from moving back to its preferred node when that node
is brought back online, until you are ready to allow it to happen.
The preferred node is the first server in the list of the assigned nodes for the
resource.
Using ConsoleOne
In ConsoleOne, right click the resource object and select Properties, then
1
select the Policies tab on the property page.
(Conditional) Check the Ignore Quorum check box if you don't want the
2
cluster-wide timeout period and node number limit enforced.
The quorum default values were set when you installed Novell Cluster
Services. You can change the quorum default values by accessing the
properties page for the Cluster object.
Checking this box will ensure the resource is launched immediately on
any server in the Assigned Nodes list as soon as any server in the list is
brought online.
Choose the Start, Failover, and Failback modes for this resource.

The default for both Start and Failover modes is AUTO, and the default
