Preparing Your Environment for Cleanroom Recovery

Prepare production workloads, Azure Cleanroom and Commvault environment to perform a recovery into a Cleanroom site.

Production Workloads

Complete the steps listed in the table below to prepare production workloads.

Workloads What to Do
Windows VMs
  1. Install the Azure VM agent on the source VM.
  2. Enable SAN Policy on the Source VM.
    Note: No reboot is required, but it is still recommended.
Linux VMs
  1. Make a snapshot or backup of the source VM before modifying it.
  2. Install Hyper-V drivers on the Source VM.
  3. In addition, perform the following steps:
    1. Edit /etc/dracut.conf, add content: 
      add_drivers+="hv_vmbus hv_netvsc hv_storvsc"
    2. Verify that no dracut conf files (for example, /usr/lib/dracut/dracut.conf.d/01-dist.conf) contain the following lines. If it contains, comment out the lines 
      hostonly="yes"  <br>
    3. Rebuild the initramfs: 
      sudo dracut -f -v  <br>
    4. Reboot the VM and verify that it is up and running.
  4. Install Azure Linux Agent on Source VMs. No reboot is required, but it is still recommended.
All Verify that all other steps required to convert VMs into Azure are successfully completed.

Azure Cleanroom

Complete the steps listed in the table below to prepare Azure Cleanroom.

Action Description
Verify the subscription Ensure your Azure Cleanroom subscription has been created.
Verify the Resource Providers are enabled in Azure Cleanroom The following Resource Providers must be enabled in Azure Cleanroom.

  • microsoft.support
  • microsoft.Storage
  • microsoft.SerialConsole
  • microsoft.ResourceNotifications
  • microsoft.ResourceGraph
  • microsoft.Portal
  • microsoft.OperationalInsights
  • microsoft.Network
  • microsoft.MarketplaceOrdering
  • microsoft.MarketplaceNotfications
  • microsoft.MachineLearning
  • microsoft.GuestConfiguration
  • microsoft.Features
  • microsoft.CostManagement
  • microsoft.Consumption
  • microsoft.Compute
  • microsoft.Commerce
    microsoft.CloudShell
  • microsoft.ClassicSubscription
  • microsoft.ChangeAnalysis
  • microsoft.Billing
  • microsoft.Authorization
  • microsoft.ADHybridHealthService

Create an Azure App Registration for Commvault Verify that an App Registration has been created for Commvault with correct permissions for the entire Cleanroom subscription and for the Storage Account (Storage Account Contributor and Storage Blob Data Contributor).
Verify the staging storage account Verify that the Resource Group and Storage Account is created with accurate configuration in the region where the VMs will be recovered (only locally-redundant storage (LRS) and StorageV2-general purpose v2-accounts are supported).

Note: Make sure that the virtual network where the access nodes will be created has access to the storage account.
Set up a virtual network for Cleanroom recovered VMs Verify the following:
Set up a virtual network for Commvault access nodes Create an additional virtual network where the auto-scaled access nodes will be created. This virtual network should have inbound and outbound connectivity to the Cleanroom recovered Control Plane (CommServe).

The following ports must be open on the additional virtual network:
  • 8400 and 8403 for Control Plane connectivity
  • 443 for AGP connectivity

Commvault Environment

Complete the steps listed in the table below to prepare Commvault environment.

Action Description
Verify the Commvault version Verify that you are using Commvault Platform Release 2024 (11.34.13) or a more recent version.
Upload CommServe Disaster Recovery (DR) backups on Commvault Cloud. Verify that the Commvault CommServe DR backups are uploaded to Commvault Cloud.

Access Cloud Command Verify that you are able to access Commvault Cloud.
Verify auxiliary copies on Air Gap Protect
  • Verify that auxiliary copy jobs on Air Gap Protect are not fallen behind and at least one full backup is completed and hosted in Cleanroom to perform recovery.
  • Verify the jobs available inside the Air Gap Protect copy and ensure that there is at least one full backup per VM.
  • Verify that the Air Gap Protect region and the Cleanroom target region are the same.

For more information, see the following topics:
Create a Cleanroom hypervisor While this task can be done in the Cleanroom using the recovered control plane, every time Cleanroom spins up it should be repeated. To stay prepared in advance, create the Cleanroom Hypervisor(s) on the production Control Plane(CommServe).
Enable auto-scaling for access nodes While this task can be done in the Cleanroom using the recovered Control Plane, every time Cleanroom spins up it should be repeated. To stay prepared in advance, enable auto-scaling for Azure access nodes in the production Control Plane(CommServe).
Create a Cleanroom recovery target While this task can be performed in the Cleanroom using the recovered Control Plane, every time the Cleanroom spins up, you must repeat this step. To stay prepared in advance, create the Cleanroom targets on the production Control Plane(CommServe).
Create Cleanroom Recovery Groups While this task can be perform in the Cleanroom using the recovered Control Plane, every time the Cleanroom spins up, you must repeat this step. To stay prepared in advance, create the Cleanroom recovery group(s) on the production Control Plane(CommServe).
Consistent Backups For VMs with databases, configure pre-scripts or application-aware backups for consistent backups
For more information, see the following topics:
Control Plane (CommServe) DR Backup on Commvault Cloud Log on to Commvault Cloud with your credentials and verify that the latest Control Plane (CommServe) DR Backups are uploaded.
