Update Rollup 18 for Azure Site Recovery

This article describes the issues that are fixed in Update Rollup 18 for the following versions of Microsoft Azure Site Recovery:

• Microsoft Azure Site Recovery Provider (version 5.1.2300.1)

• Microsoft Azure Site Recovery Unified Setup (VMware to Azure) (version: 9.9.4510.1)

We recommend that you review the details of the issues that are fixed and verify the prerequisites before you install this update.

Update Rollup 18 for Microsoft Azure Site Recovery Provider applies to all systems that have Microsoft Azure Site Recovery Service Provider installed. These include the following:

• Microsoft Azure Site Recovery Provider for System Center Virtual Machine Manager (3.3.x.x)

• Microsoft Azure Site Recovery Hyper-V Provider (4.6.x.x)

• Microsoft Azure Site Recovery Provider (5.1.x.x)

Update Rollup 18 for Microsoft Azure Site Recovery Unified Setup (VMware to Azure) applies to all systems that have Microsoft Azure Site Recovery Services Unified Setup version 9.0.4016.1 or a later version installed.

After you apply this update, the following issues are fixed, and the following improvements are included.

Microsoft Azure Site Recovery Provider

Issues fixed

• Additional logging added to improve diagnosis ability.

• Fixes to improve the reliability of the registration operation.

Microsoft Azure Site Recovery Unified Setup

Issues fixed

• Dependency on the .NET Framework 3.5 is removed because the .NET Framework 3.5 is approaching its end of life.

• Improved logging and error messages for installation failures.

• Fixes in uninstallation code to clean up firewall rules that were set up during installation.

Mobility Service

Improvements

• Support for Ubuntu 14.04 LTS. For a list of supported kernels, go to Support for replicated machine OS versions.

• Migration (migrate from on-premises to Azure) support for Red Hat Enterprise Linux release 7.3.

• Migration (migrate from on-premises to Azure) support for CentOS 7.3. Failback support will be added in the next monthly release.

• When you use System Center Configuration Manager or other deployment tools, you might require the ability to deploy Mobility Service on your Server without having to register it with a Configuration Server. In this release, support is added in the installer that lets you install the Mobility Service without having to immediately register it with a Configuration Server. For more information, go to Install Mobility Service (VMware or physical to Azure).

Microsoft Azure Site Recovery (service-side fixes)

Improvements

• Support for creating virtual machines (VMs) by using managed disks on failover to Azure for on-premises VMware and Hyper-V sites (managed or not managed by VMM). You will be able to turn on or turn off the option to use managed disks in the Compute and Network settings for the protected VM. Managed Disks that are created on failover to Azure simplify disk management for Azure IaaS VMs by managing the storage accounts that are associated with the VM disks. Also, managed disks provide better reliability for Availability Sets by making sure that the disks of VMs in an Availability Set are sufficiently isolated from one another to avoid single points of failure.
   

  • Note Failback from Azure to on-premises Hyper-V sites (managed by or not managed by VMM) is not supported for VMs that run on managed disks.

• Optimized failover performance for VMware VMs failing over to Azure: Time taken to fail over VMware VMs to Azure is reduced by optimization in the failover process. VMs that meet the following criteria benefit from this optimization:
   
  • Windows VM that is running on VMware.
  • VMs that use mobility service version 9.8 or a later version.
  • VMs that have the following boot drivers:
     
    • storvsc
    • atapi
    • intelide
    • storflt
    • vmbus
  • VMs that have the DHCP service enabled. The VM can also use a Static IP address.
  Notes
   
  • Hyper-V VMs that are protected as physical machines will not benefit from this optimization.
  • Hyper-V VMs that are protected from Hyper-V hosts were being failed over by using the optimized path even before this recent change.
• Many eroor messages are improved based on customer experience and recent issues. Three of the top issues are the following:
   
  • Error Code 95226 This error is usually seen when the failed-over VM in Azure cannot connect to the on-premises Configuration server. This can happen when either of the following conditions are true:
     

    • You have to make sure that the network of the Azure VM is configured to enable the VM to communicate with the on-premises Configuration server. To do this, either set up a Site-to-Site VPN back to your on-premises datacenter or configure an ExpressRoute connection that uses private peering on the virtual network of the Azure VM.

    • If you already have a network configured to enable the Azure VM to communicate with the on-premises configuration server, log in to the VM, and then check the "InMage Scout Application Service." If you see that the InMage Scout Application Service" is not running, start the service manually and make sure that the service start type is set to Automatic.

  • Error Code 78093 This error occurs when the failed-over Azure VM is not running. Start the Azure VM or, if the Azure VM is already running, make sure that the operating system is not hanging. Also, make sure that the Azure VM can communicate with the on-premises Configuration server and at least one process server. Then, retry the reprotect operation.
  • Error Code 8072 This error occurs when the on-premises master target has a SCSI controller other than LSI Logic Parallel. Select a master target server that has only LSI Logic Parallel SCSI controllers. Or, on the master target, change the SCSI controller type to LSI Logic Parallel. Then, restart the job.
• If you provided a wrong set of inputs during the Azure-to-VMware failback, and the job fails, you can now return to the VM in the protected items list and re-trigger reprotect. This enables you to enter new inputs and successfully complete reprotection.
  
  NoteIf the failure occurred after the on-premises VM disks are attached to the master target, you cannot change the master target input. If you change the input on a retrigger, the job fails because the disks are already attached. Therefore, make sure that only the first master target that is selected is used for a retrigger.

• You can use Azure Hybrid Use Benefit to bring your own Windows Server license to VMs that are migrated or failed-over to Azure through Azure Site Recovery. In addition to using Windows PowerShell, you now have the option in the Azure portal experience for Azure Site Recovery to specify that Azure Hybrid Use Benefit should be used for a protected VM. 

Issues fixed

• Failback of a VM from Azure to Hyper-V fails and returns Error Code 539. Additionally, you receive the following error message:
   
  The requested action couldn't be performed by the 'Hyper-V Replica To Azure' Replication Provider.
