Start-HpcNode [-Name] <String[]> [-Scheduler <String> ] [ <CommonParameters>]

Parameter Set: Node


Start-HpcNode -Node <HpcNode[]> [-Scheduler <String> ] [ <CommonParameters>]

Detailed Description

Turns on one or more compute nodes using preconfigured Intelligent Platform Management Interface (IPMI) script. Your computer vendor should have configured the IPMI script for your computer. If the IPMI script is not configured, Start-HpcNode generates an error.

Parameters

-Name<String[]>

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

Aliases	none
Required?	true
Position?	1
Default Value	no default
Accept Pipeline Input?	false
Accept Wildcard Characters?	true

-Node<HpcNode[]>

Specifies one or more HpcNode objects for the nodes that you want to turn on. You cannot specify both the Node and Name parameters.

Aliases	none
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>

Aliases	none
Required?	false
Position?	named
Default Value	%CCP_SCHEDULER%
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

<CommonParameters>

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

Inputs

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

One or more HpcNode objects.

Outputs

The output type is the type of the objects that the cmdlet emits.

None.

Notes

You must be a cluster administrator to run this cmdlet successfully.

Examples

EXAMPLE 1

Turns on a node named hpc01cn02.

	Copy Code
Start-HpcNode -Name "hpc01cn02"

EXAMPLE 2

Gets the HpcNode objects for all of the nodes in the group named maintenance, and turns on those nodes.

	Copy Code
Get-HpcNode -GroupName maintenance \| Start-HpcNode
