Appendix 3: Node Template Tasks and Properties

  • 项目

You can use the Node Template Editor in HPC Cluster Manager to add deployment, configuration, and maintenance tasks to a node template. Some of these tasks are added to new templates when you create them using the Create Node Template Wizard.

To add tasks to a node template using the Node Template Editor

  1. If HPC Cluster Manager is not already open on the head node, open it. Click Start, point to All Programs, click Microsoft HPC Pack, and then click HPC Cluster Manager.

  2. In Configuration, click Node Templates.

  3. In the Views pane, click the node template to which you want to add tasks.

  4. In the Actions pane, click Edit. The Node Template Editor appears.

  5. To add a task, click Add Task, and then click the task that you want to add from the list of available tasks. For more information about each node task and its parameters, see Available node template tasks.

  6. Repeat the previous step for all tasks that you want to add to the node template. After you are done adding tasks, click Save.

Available node template tasks

There are four types of node template tasks:

  • Provisioning

  • Configuration

  • Deployment

  • Maintenance

Provisioning

Provisioning tasks are performed on the head node before the deployment process of the compute nodes takes place. The following table lists the provisioning task that you can add or modify on a node template, and the properties that are associated with it.

Task Name Task Description Properties

Create Computer Account

Creates a computer account in Active Directory for the compute node.
  • Domain (optional): specifies the name of the domain on which the computer account will be created. If this property is not specified, the domain of the head node is used.

  • ComputerPath (optional): specifies the path in Active Directory where the computer account will be created. The default path is cn=Computers. If this property is not specified, the computer path of the head node is used.

ImportantImportant
When you specify one of these two properties, you must also specify the other one. If you only specify one property, it will be ignored and the domain and computer path of the head node will be used.

Configuration

Configuration tasks are performed on a compute node after the compute node is booted into Windows Preinstallation Environment (Windows PE) at the beginning of the deployment process. The following table lists the configuration tasks that you can add or modify on a node template and the properties that are associated with each.

Task Name Task Description Properties

Run Windows PE Command

Runs a command in Windows PE.
  • ContinueOnFailure (optional): if True is selected, the configuration task will not fail if the command fails to run successfully. If False is selected, the configuration task will fail if the command fails to run successfully.

  • ErrorWhiteList (optional): specifies the return error codes that should be ignored for the command. The default return code that is expected from the command when it runs successfully is zero (0). If the command returns a success code other than zero, then you must add that return code to the list of error codes that should be ignored, or it will be interpreted as an error code and the task will fail.

  • Command (required): specifies the Windows PE command that you want to run.

Multicast Copy

Copies a file from the head node using the multicast protocol.
  • UnicastFallback (optional): if True is selected and multicast fails, the file will be copied using the Server Message Block (SMB) protocol. If False is selected and multicast fails, the task will fail.

  • DestFile (required): specifies the absolute path to the drive of the compute node to which the file will be copied. If you have added the Partition Disk task to the node template, ensure that you specify a path that is valid for the partitions that will be created with that task.

  • SourceFile (required): specifies the name and path of the file to copy, relative to the Microsoft HPC Pack\Data\InstallShare folder.

Unicast Copy

Copies a file from the head node using the Server Message Block (SMB) protocol.
  • Directory (optional): specifies if a file (False) or a folder (True) is being copied.

  • Destination (required): specifies the absolute path to the drive of the compute node to which the file will be copied. If you have added the Partition Disk task to the node template, ensure that you specify a path that is valid for the partitions that will be created with that task.

  • Source (required): specifies the name and path of the file to copy, relative to the Microsoft HPC Pack\Data\InstallShare folder.

Partition Disk

Partitions the disk on the compute node using a script for Diskpart.
  • DiskPartScript (Required): specifies the name and path of the script to use with Diskpart.

Mount Share

Shares a folder during the Windows PE phase of the operating system installation.
  • DriveLetter (optional): specifies the drive letter where the folder will be shared.

  • User (optional): specifies the user name to use when sharing the folder.

  • UserPassword (optional): specifies the password to use when sharing the folder.

  • Path (required): specifies the name and path of the folder that will be shared.

Install Windows

Installs the Windows Server operating system on the compute node.
  • Custom Unattend File (optional): specifies the absolute path to the custom unattend file to use for installation.

  • Installation Drive (optional): specifies the drive letter where the Windows Server operating system will be installed. If you have added the Partition Disk task to the node template, ensure that you specify a drive letter that is valid for the partitions that will be created with that task.

  • Local Administrator password (optional): specifies the password for the local Administrator account on the compute node.

  • Product Key (optional): specifies the product key to use with this node template for the activation of the operating system.

  • Autogenerate Local Admin Password (required): if True is selected, the password for the local Administrator account is automatically generated. After a password is automatically generated, it is secret and cannot be recovered. If False is selected, then you should specify a password using the Local Administrator password attribute.

  • Image (required): specifies the image to use for the installation of the operating system.

Apply WIM Image

Extracts the files in a WIM file to a local disk on the compute node.
  • DestinationPath (required): specifies the path on the compute node where the files in the Windows Imaging Format (WIM) file will be extracted. If you have added the Partition Disk task to the node template, ensure that you specify a path that is valid for the partitions that will be created with that task.

  • WimPath (required): specifies the path on the compute node where the WIM file that will be extracted is stored.

Restart

Restarts the compute node.
  • None

Deployment

Deployment tasks are performed on a compute node after the operating system has been installed. The following table lists the deployment tasks that you can add or modify on a node template and the properties that are associated with each.

Task Name Task Description Properties

Unicast Copy

Copies a file from the head node using the Server Message Block (SMB) protocol.
  • Directory (optional): specifies if a file (False) or a folder (True) is being copied.

  • ContinueOnFailure (optional): if True is selected, deployment will not fail if the command fails to run successfully. If False is selected, deployment will fail if the command fails to run successfully.

  • ErrorWhiteList (optional): specifies the return error codes that should be ignored for the command. The default return code that is expected from the command when it runs successfully is zero (0). If the command returns a success code other than zero, then you must add that return code to the list of error codes that should be ignored, or it will be interpreted as an error code and the task will fail.

  • Command (required): specifies the command that you want to run as Administrator.
