Start-HpcNodeSet

Updated: January 10, 2014

Start-HpcNodeSet

Starts a set of Windows Azure nodes.

Syntax

Parameter Set: Default
Start-HpcNodeSet -Template <HpcNodeTemplate> [-Async <Boolean> ] [-Scheduler <String> ] [ <CommonParameters>]




Detailed Description

Starts the set of Windows Azure nodes that use the specified node template. When you start a set of nodes, you deploy a set of role instances for the nodes in Windows Azure.

Parameters

-Async<Boolean>

Specifies whether the cmdlet should return immediately without waiting for the nodes to start.

A nonzero or $true value specifies that the cmdlet should return immediately without waiting for the nodes to start. A 0 or $false value specifies that the cmdlet should wait for the nodes to start before returning.


Aliases

Required?

false

Position?

named

Default Value

$false

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 set of Windows Azure nodes that you want to start. 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

-Template<HpcNodeTemplate>

Specifies an HpcNodeTemplate object that corresponds to the node template that is associated with the set of Windows Azure nodes that you want to start.

The node template that you specify must be a Windows Azure node template. An error occurs if you specify a different type of node template.


Aliases

none

Required?

true

Position?

named

Default Value

no default

Accept Pipeline Input?

true (ByValue)

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.

  • An HpcNodeTemplate object.

Outputs

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

  • None.

Notes

  • All of the nodes that you add to an HPC cluster by using a specific node template define a set of nodes that are deployed and can be managed together in Windows Azure when you start the nodes. This set includes nodes that you add later by using the same node template. You can start the entire set of nodes, but not individual nodes.

  • The deployment of role instances in Windows Azure can take several minutes if you start a large number of nodes.

  • If a problem exists with your Internet connection or with the connection information for Windows Azure in the specified node template, the deployment of the nodes can fail.

  • When you start a set of nodes, additional proxy role instances are configured in Windows Azure to facilitate communication between HPC Cluster Manager and the nodes. Starting in HPC Pack 2012, the number of proxy nodes can be configured in the Windows Azure node template. These proxy instances appear in the Windows Azure Management Portal, incur charges in Windows Azure, and count toward the quota for role instances in the Windows Azure subscription.

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

  • This cmdlet was introduced in HPC Pack 2008 R2 with Service Pack 1 (SP1). It is not supported in previous versions.

Examples

Example 1

Gets an HpcNodeTemplate object for the node template named MyWorkerNodeTemplate, then starts all of the nodes that are associated with that node template from the HPC cluster and returns without waiting for the nodes to start.


PS C:\>Get-HpcNodeTemplate -Name MyWorkerNodeTemplate | Start-HpcNodeSet -Async $true
