Remove-HpcNode

Removes the entry for one or more compute nodes from the database on the head node.

Syntax

Remove-HpcNode [-Comment <string>] [-Scheduler <string>] [-Name] <string[]> [-confirm] [-whatif] [<CommonParameters>]

Remove-HpcNode [-Comment <string>] [-Scheduler <string>] -Node <HpcNode[]> [-confirm] [-whatif] [<CommonParameters>]

Detailed Description

Removes the entry for one of more compute nodes from the database on the head node. This cmdlet does not delete Microsoft® HPC Pack 2008 on the compute nodes. To delete a node completely, you need to uninstall HPC Pack 2008 as well. You can use HPC Cluster Manager to add compute nodes that you deleted back to the cluster. HPC Cluster Manager is able to rediscover these deleted compute nodes.

Parameters

-Comment <string>

Specifies a comment for the node removal.

-Scheduler <string>

Specifies the host name or IP address of the head node for the cluster that includes the nodes. The value must be a valid computer name or IP address. If you do not specify the Scheduler parameter, this cmdlet uses the scheduler on the head node that the CCP_SCHEDULER environment variable specifies. To set this environment variable, run the following cmdlet:
