Add Role

Updated: August 21, 2014

The Add Role operation adds a Virtual Machine to a deployment of Virtual Machines. Before you run this operation, you must have an existing cloud service and deployment in Microsoft Azure. To create a cloud service, you can use Create Cloud Service. To create a deployment, you can use Create Virtual Machine Deployment.

The Add Role request may be specified as follows. Replace <subscription-id> with the subscription ID, <cloudservice-name> with the name of the cloud service, and <deployment-name> with the name of the deployment.

 

Method Request URI

POST

https://management.core.windows.net/<subscription-id>/services/hostedservices/<cloudservice-name>/deployments/<deployment-name>/roles

You must make sure that the request that is made to the management service is secure. For additional details, see Authenticating Service Management Requests.

Required. Specifies the properties that are used to create a data disk.

HostCaching

Optional. Specifies the caching behavior of the data disk for read/write efficiency. Setting this property impacts the consistency of the disk.

Possible values are:

  • None

  • ReadOnly

  • ReadWrite

The default value is None.

DiskLabel

Optional. If the disk that is being added is already registered in the subscription, this element is ignored. If a new disk is being created, this element is used to provide a description of the disk. The value of this element is only obtained programmatically and does not appear in the Management Portal.

DiskName

Optional. If the disk that is being added is already registered in the subscription, this element is used to identify the disk to add. If a new disk and the associated VHD is being created by Azure, this element is not used and Azure assigns a unique name that is a combination of the deployment name, role name, and identifying number.

The name of the disk must contain only alphanumeric characters, underscores, periods, or dashes. The name must not be longer than 256 characters. The name must not end with period or dash.

Lun

Optional. Specifies the Logical Unit Number (LUN) for the data disk. If the disk is the first disk that is added, this element is optional and the default value of 0 is used. If more than one disk is being added, this element is required.

You can use Get Role to find the LUN numbers that are already being used.

Valid LUN values are 0 through 31.

LogicalDiskSizeInGB

Optional. Specifies the size, in GB, of an empty disk to be attached to the Virtual Machine. If the disk that is being added is already registered in the subscription, this element is ignored. If the disk and VHD is being created by Azure as it is added, this element defines the size of the new disk.

The number of disks that can be added to a Virtual Machine is limited by the size of the machine. For more information, see Virtual Machine and Cloud Service Sizes for Azure.

This element is used with the MediaLink element.

MediaLink

Optional. If the disk that is being added is already registered in the subscription or the VHD for the disk already exists in blob storage, this element is ignored. If a VHD file does not exist in blob storage, this element defines the location of the new VHD that is created when the new disk is added.

Example:

http://example.blob.core.windows.net/disks/mydatadisk.vhd

SourceMediaLink

Optional. If the disk that is being added is already registered in the subscription or the VHD for the disk does not exist in blob storage, this element is ignored. If the VHD file exists in blob storage, this element defines the path to the VHD and a disk is registered from it and attached to the virtual machine.

Contains the parameters that are used to create the operating system disk for a Virtual Machine.

 

Element name Description

HostCaching

Optional. Specifies the caching mode of the operating system disk. This setting impacts the consistency and performance of the disk.

Possible values are:

  • ReadOnly

  • ReadWrite

The default value is ReadWrite.

noteNote
Changing this value causes the Virtual Machine to reboot.

DiskLabel

Optional. Specifies the description of the disk.

DiskName

Required if an existing disk is being used to create a Virtual Machine. Specifies the name of a new or existing disk. For a new disk, if this element is not specified, a unique name is assigned that is a combination of the deployment name, role name, and identifying number.

The name of the disk must contain only alphanumeric characters, underscores, periods, or dashes. The name must not be longer than 256 characters. The name must not end with period or dash.

MediaLink

Required if the Virtual Machine is being created from a platform image. Specifies the location of the VHD file that is created when SourceImageName specifies a platform image. This element is not used if the Virtual Machine is being created using an existing disk.

Example:

http://contoso.blob.core.windows.net/disks/mydisk.vhd

SourceImageName

Optional. Specifies the name of the image to use to create the Virtual Machine. You can specify a user image or a platform image. An image is always associated with a VHD, which is a .vhd file stored as a page blob in a storage account in Azure. If you specify a platform image, an associated VHD is created and you must use the MediaLink element to specify the location in storage where the VHD will be located.

OS

Required if RemoteSourceImageLink is used. Specifies the type of operating system that is installed in the image.

Possible values are:

  • Windows

  • Linux

RemoteSourceImageLink

Optional. Specifies a URI to the location where an OS image is stored that is used to create the Virtual Machine. An image is always associated with a VHD, which is a .vhd file stored as a page blob in a storage account in Windows Azure. If you specify the path to an image with this element, an associated VHD is created and you must use the MediaLink element to specify the location in storage where the VHD will be located. If this element is used, SourceImageName is not used.

The RemoteSourceImageLink element is only available using version 2014-05-01 or higher.

ResizedSizeInGB

When an OS Image or a RemoteSourceImage is used to create an OSVirtualHardDisk, this parameter can be used to resize the new OSVirtualHardDisk to a larger size. ResizedSizeInGB must be larger than the underlying OS Image’s LogicalSizeInGB. The ResizedSizeInGB element is only available using version 2014-10-01 or higher.

When a VM Image is used to create a new PersistantVMRole, the DiskConfigurations in the VM Image are used to create new Disks for the new VM. This parameter can be used to resize the newly created Disks to a larger size than the underlying DiskConfigurations in the VM Image.
