Gets a list of one or more nodes in the HPC cluster that meet the specified criteria.

Syntax

Get-HpcNode [-Group <HpcGroup>] [-GroupName <string[]>] [-Health <NodeHealth[]>] [-Scheduler <string>] [-State <ClusterNodeState[]>] [-TemplateName <string[]>] [[-Name] <string[]>] [<CommonParameters>]

Detailed Description

Gets a list of one or more nodes in the HPC cluster that meet the specified criteria for name, group, health, node template, or node state.

Parameters

-Group <HpcGroup>

Specifies the HpcGroup object for the node group that contains the nodes that you want to get. You cannot specify both the Group and the GroupName parameters.

 

Required?

false

Position?

named

Default Value

no default

Accept Pipeline Input?

true (ByValue)

Accept Wildcard Characters?

false

-GroupName <string[]>

Specifies a list of names for the node groups that contain the nodes that you want to get. The cmdlet gets nodes that belong to multiple groups only once. You cannot specify both the GroupName and the Group parameters.

 

Required?

false

Position?

named

Default Value

no default

Accept Pipeline Input?

false

Accept Wildcard Characters?

false

-Health <NodeHealth[]>

Specifies the health of the nodes that you want to get. The possible values for the Health parameter are OK, Unreachable, OngoingOperation, DiagnosticFailed, and ProvisioningFailed.

 

Required?

false

Position?

named

Default Value

the combination of all health values

Accept Pipeline Input?

false

Accept Wildcard Characters?

false

-Name <string[]>

Specifies a list of one or more names for the nodes that you want to get.

 

Required?

false

Position?

1

Default Value

no default

Accept Pipeline Input?

false

Accept Wildcard Characters?

false

-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:

Set-Content Env:CCP_SCHEDULER <head_node_name>

 

Required?

false

Position?

named

Default Value

%CCP_SCHEDULER%

Required?

false

Position?

named

Default Value

the combination of all state values

Accept Pipeline Input?

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see about_CommonParameters.

Input and Return Types

The input type is the type of the objects that you can pipe to the cmdlet. The return type is the type of the objects that the cmdlet emits.

 

Input Type

An HpcGroup object.

Return Type

One or more HpcNode objects.

Example 1

C:\PS>Get-HpcNode -TemplateName "ApplicationA"

Gets all compute nodes that use the node template named ApplicationA. You can set up nodes to have a particular node template when you provision the nodes for a particular application.

Example 2

C:\PS>Get-HpcNode -Health OK

Gets all healthy nodes.

Example 3

C:\PS>Get-HpcNode -State Offline

Gets all offline nodes.
