The circumstances MSCS uses to take a group offline on the
primary (preferred) node and online on the secondary node.
The circumstances MSCS uses to bring a group offline on the
secondary node and online on the primary (preferred) node.
The cluster node you want the cluster group to run on when the
cluster is in a normal state.
The number of times MSCS will attempt to fail over a group within
a specified failover period.
The length of time in which MSCS attempts to fail over a cluster
group. When the failover threshold count has been exceeded
within the failover period, MSCS leaves the group on its current
node, in its current state.
Example: If the failover threshold = 5 and the failover period = 1,
MSCS will attempt to fail over the group 5 times within a 1-hour
period.
Prevent automatic failback. This setting allows the administrator
to fail back a group manually.
Allow automatic failback. This setting allows MSCS to fail back a
group automatically.
This setting allows automatic failback as soon as the preferred
node is reintegrated into the cluster and brought back online.
This setting allows the administrator to determine specific hours
of the day during which automatic failback can occur.
