Detailed Description

The New-HpcGroup cmdlet creates a node group with the specified name and description.

Parameters

-ClusterConnectionString<String[]>

Specifies an array of cluster connection strings for the cluster to which you want to add the device drivers. The value format is host1,host2,host3. If you do not specify the ClusterConnectionString parameter, this cmdlet uses the connection string on the head node that the CCP_CONNECTIONSTRING environment variable specifies. To set this environment variable, run the following cmdlet: Set-Content Env: CCP_CONNECTIONSTRING <head_node_name>.

This parameter was introduced in HPC Pack 2016.
