CLUSTER GROUP

You can use cluster commands to administer server clusters from the Windows command prompt. You can also call the program from command scripts to automate many cluster administration tasks. Cluster is provided on all Windows computers.

You can administer clusters from a node of the cluster, from nodes of other clusters, or from other computers running Windows NT 4.0 with Service Pack 3 or later.

/HELP | /? (NT2000)

Display cluster group syntax. Default.

/CLUSTER (NT2000)

If you do not specify a cluster, attempts to connect to the cluster running on the node that is running the command.

If the name of your cluster is also a cluster command or its abbreviation, use /cluster: to explicitly specify the cluster name.

/CREATE (NT2000)

Create a new group.

/DELETE (NT2000)

Delete a group.

/LISTOWNERS (NT2000)

Display a list of preferred owners.

/MOVE[TO][:node_name] (NT2000)

Move a group to another node.

/NODE:node_name (NT2003)

Specifies the node that owns the group.

/OFF[LINE][:node_name] (NT2000)

Take a group offline.

/ON[LINE][:node_name] (NT2000)

Bring a group online.

/PRIV[PROPERTIES] (NT2000)

View or set the cluster private properties.

By default, there are no private properties for cluster group. Software vendors can add private properties to extend cluster functionality.

/PROP[ERTIES] (NT2000)

View or set the cluster common properties.

/REN[AME]:group_name (NT2000)

Rename a group.

/SETOWNERS:node_name[,node_name ...] (NT2000)

Specify a preferred owner.

/STAT[US] (NT2000)

?

/WAIT[:time_seconds] (NT2000)

How long to wait before canceling the command if it does not successfully complete. If a time-out is not specified, waits indefinitely or until the group state changes.

Common group property names:

• AutoFailbackType Set to ClusterGroupPreventFailback (0) to prevent failback. Set to ClusterGroupAllowFailback (1) to allow failback
• Description Describes a group
• FailoverPeriod Specifies the interval (in hours) over which the Cluster service attempts to fail over a group
• FailoverThreshold Specifies the number of times the Cluster service attempts to fail over a group before it concludes that the group cannot be brought online anywhere in the cluster
• FailbackWindowEnd Specifies the end time (on a 24-hour clock) for failback of a group to its preferred node. These values must be between 0 (midnight) and 23 (11:00 p.m.) in local time. For immediate failback, set to -1
• FailbackWindowStart Specifies the start time (on a 24-clock) for failback of a group to its preferred node. These values must be between 0 (midnight) and 23 (11:00 p.m.) in local time. For immediate failback, set to -1
• Name Name of the cluster group object
• PersistentState Describes the last known persistent state of a group (1, (true) means online; 0 (false) means offline)
