AzureDisk agent

Virtual machines in Azure use data disks to store the applications data. The AzureDisk agent supports managed and unmanaged data disks and provides high availability of these disks during fail-over of an application.

The AzureDisk agent brings online, takes offline, and monitors the managed and unmanaged Azure data disks. It attaches the managed and unmanaged data disks to a virtual machine of the same or different resource group. The AzureDisk agent uses Azure Python SDK to determine whether the Azure data disks are attached to the Azure virtual machines or not.

Prerequisite

Configure the AzureAuth agent.

See AzureAuth agent.

Dependencies

The Azure disk resources depend on the AzureAuth resource.

Figure: Sample service group dependency

os_winSample service group dependency
Agent functions

Open

Fetches the name of the Azure VM.

Online

Attaches Azure data disk to the Azure VM.

Offline

Detaches Azure data disk from the Azure VM.

Monitor

Determines if the Azure data disk is attached to the current Azure VM or not.

Clean

Terminates all ongoing resource actions and detaches the Azure data disk from the Azure VM.

State definitions

ONLINE

Indicates that the Azure data disk is attached to the Azure VM.

OFFLINE

Indicates that the Azure data disk is detached from the Azure VM.

FAULTED

Indicates that the Azure data disk was unexpectedly detached from the Azure VM outside of VCS control.

UNKNOWN

Indicates that a problem exists because of one of the following reasons:

  • Azure Python SDK is not installed

  • Azure VM is not found in the specified Resource Group

  • Azure data disk is not configured correctly or has invalid ID

  • Roles are not configured correctly or attached to the instance

  • The disks are attached to Azure VM of another cluster

  • DiskIds has a combination of managed and unmanaged disks

  • Configured unmanaged disks belong to different storage accounts

Attributes

Table: Required attributes

Attribute

Description

DiskIds

In case of managed disks, resource ID of the disk.

In case of unmanaged disks, VHDUri of the disk.

You can add one or more disk Ids separated by a space.

Type and dimension: string-vector

VMResourceGroup

Azure resource group where the Azure VM resides.

Type and dimension: string-scalar

AzureAuthResName

Name of the authentication agent resource that handles Azure related authentication.

Type and dimension: string-scalar

StorageAccountKey

Access key of the storage account.

You must encrypt this key by using the vcsencrypt utility. For details, see the Cluster Server Administrator's Guide.

This attribute is required only if unmanaged disks are configured.

Type and dimension: string-scalar

Table: Optional attribute

Attribute

Description

AzureVMName

Name of the VM in Azure on which agent is running.

Type and dimension: string-scalar

Sample configuration

Sample configuration with managed disks:

      resourceGroups/azureRG/providers/Microsoft.Compute/disks/
      AzureManagedDisk" }
    VMResourceGroup = "azureVMRG"
    AzureAuthResName = "azure-auth-res"
)

Sample configuration with unmanaged disks:

AzureDisk azure-res-disk (
    DiskIds = { "https://azureunstorageaccount2.blob.core.windows.net/
      vhds/unmanageddisk.vhd" }
    VMResourceGroup = "azureVMRG"
    AzureAuthResName = "azure-auth-res"
    storageAccountKey = fpjNjrNrgRupNnnLhlKHnlRjpKLitIpjTgnTpfNglSls
)
Debug log levels

The AzureDisk agent uses the DBG_1 debug log level.
