Parameters
| Parameter | Description |
|---|---|
| /scheduler:<name> | Specifies the host name or IP address of the head node for the cluster that contains the node. The value must be a valid computer name or IP address.

If you specify a node that is already offline, in the process of going offline, or in the process of coming online, this command fails. Specify only valid nodes that are currently online for this command.
You must be a cluster administrator to run this command successfully.
