Shutdown-HpcNode

Turns off one or more compute nodes.

Syntax

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

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

Detailed Description

Turns off one or more compute nodes. If you do not have an Intelligent Platform Management Interface (IPMI) script that your computer vendor configured, you may not be able to start the node again remotely. By default, this cmdlet sends a shutdown command to the operating system, but computer vendors can change the configuration to add IPMI-based commands.

Parameters

-Comment <string>

Specifies a comment that provides a reason that you turned off the nodes.

 

Required?

false

Position?

named

Default Value

no default

Accept Pipeline Input?

false

Accept Wildcard Characters?

false

-Name <string[]>

Specifies a list of the names of the nodes that you want to turn off. You cannot specify both the Name and Node parameters.

 

Required?

true

Position?

1

Default Value

no default

Accept Pipeline Input?

false

Accept Wildcard Characters?

true

-Node <HPCNode[]>

Specifies a list of HpcNode objects that correspond to the nodes that you want to turn off. Use the Get-HpcNode cmdlet to get an HpcNode object for a node. You cannot specify both the Node and Name parameters.

 

Required?

true

Position?

named

Default Value

no default

Accept Pipeline Input?

true (ByValue)

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%

Accept Pipeline Input?

false

Accept Wildcard Characters?

false

-Confirm

Prompts you for confirmation before executing the command.

 

Required?

false

Position?

named

Default Value

none

Accept Pipeline Input?

false

-WhatIf

Describes what would happen if you executed the command without actually executing the command.

 

Required?

false

Position?

named

Default Value

none

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

One or more HpcNode objects.

Return Type

None.

Example 1

C:\PS>Get-HpcNode -GroupName old | Shutdown-HpcNode

Gets the HpcNode objects for all nodes in the node group named old and shuts down those nodes.

Example 2

C:\PS>Shutdown-HpcNode -Name MyComputeNode

Shuts down the node named MyComputeNode.
