Retaining virtual machines of Virtual SAN Beta cluster when upgrading to vSphere 5.5 Update 1 (2074147)

Details

If you are upgrading ESXi and vCenter Server from 5.5 to 5.5 Update 1, you cannot continue to use Virtual SAN beta datastores. vSphere 5.5 Update 1 supports Virtual SAN 5.5 only. Upgrading Virtual SAN beta to Virtual SAN 5.5  is not supported.
To continue using  virtual machines that belong to Virtual SAN beta datastore, you need to migrate the virtual machines to another non-Virtual SAN datastore before upgrading ESXi and vCenter Server to 5.5 Update 1.


Solution

To continue using virtual machines that belong to Virtual SAN beta cluster, you need to perform the following steps in sequence when upgrading ESXi and vCenter Server to 5.5 Update1:
  1. Migrate all virtual machines from the Virtual SAN datastore to a non-Virtual SAN datastore, such as a shared VMFS or NFS type datastore.
    Note
    : The storage compliance status of virtual machines might be displayed as Not Compliant or Not Applicable. You can ignore it as this will resolve after you have migrated the virtual machines back to the Virtual SAN 5.5 cluster at the end of this procedure.   
  2. Remove Virtual SAN disks groups from all hosts in the Virtual SAN beta cluster.
    1. Browse to the Virtual SAN cluster in the vSphere Web Client navigator.
    2. Click the Manage tab and click Settings.
    3. Under Virtual SAN, click Disk Management
    4. Remove the disk group.   
  3. Disable Virtual SAN.
    1. Browse to the host cluster in the vSphere Web Client navigator.     
    2. Click the Manage tab and click Settings.         
    3. Under Virtual SAN, select General and click Edit.     
    4. Deselect the Turn On Virtual SAN check box.    
  4. Upgrade vCenter Server to vCenter Server 5.5 Update 1. 

    Note: The version of vCenter Server to be upgraded must be generally available. Upgrading a beta release version to the GA release version is not supported. 

  5. Place the ESXi 5.5 hosts that you are upgrading in maintenance mode. 
  6. Upgrade ESXi 5.5 hosts to ESXi 5.5 Update 1.

    Note: The version of ESXi to be upgraded must be generally available. Upgrading a beta release version to the GA release version is not supported. 

  7. After all ESXi hosts are upgraded to 5.5 Update1, enable Virtual SAN 5.5 on a cluster.    
    1. Browse to the host cluster in the vSphere Web Client navigator.     
    2. Click the Manage tab and click Settings.         
    3. Under Virtual SAN, select General and click Edit to edit Virtual SAN settings.     
    4. Select the mode for storage disks to be claimed and click OK.                        
  8. Create Virtual SAN disk Group on hosts in the Virtual SAN 5.5 cluster.
    1. Browse to the Virtual SAN cluster in the vSphere Web Client navigator.     
    2. Click the Manage tab and click Settings.     
    3. Under Virtual SAN, click Disk Management.     
    4. Select the disk group, and click the Add a disk to the selected disk group icon.     
    5. Select a disk to add and click OK
  9. Migrate the virtual machines back to the Virtual SAN 5.5 datastore.            
  10. Check for storage policy compliance on all the virtual machines.
