Details

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


Solution

To continue using virtual machines that belong to vSAN 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 vSAN datastore to a non-vSAN 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 vSAN 5.5 cluster at the end of this procedure.   
  2. Remove vSAN disks groups from all hosts in the vSAN beta cluster.
    1. Browse to the vSAN cluster in the vSphere Web Client navigator.
    2. Click the Manage tab and click Settings.
    3. Under vSAN, click Disk Management
    4. Remove the disk group.   
  3. Disable vSAN.
    1. Browse to the host cluster in the vSphere Web Client navigator.     
    2. Click the Manage tab and click Settings.         
    3. Under vSAN, 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 vSAN 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 vSAN, select General and click Edit to edit vSAN settings.     
    4. Select the mode for storage disks to be claimed and click OK.                        
  8. Create vSAN disk Group on hosts in the vSAN 5.5 cluster.
    1. Browse to the vSAN cluster in the vSphere Web Client navigator.     
    2. Click the Manage tab and click Settings.     
    3. Under vSAN, 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 vSAN 5.5 datastore.            
  10. Check for storage policy compliance on all the virtual machines.
