1. Navigate to each Nimble host (MRS and RLA management)

  2. Create new data volume protection policy for the new LUN, copy settings from each site: https://10.21.124.84/manage/protection/volume_collections- creating one will replicate in the other site (double check once you've created)

  3. Create the storage device in data storage, ensure you click more options when doing so to get the full UI. Ensure settings are similar to below.
    Notes:
    Ensure that both multiple initiator access is enabled for both access groups.

    Example below:





  4. Once created, ensure the new LUN is visible from each host.

  5. Navigate to vSphere

  6. Click on each ESXI host, click configure > storage > storage adaptors > rescan storage.

  7. Once you rescanned all ESXI hosts, click configure > storage > storage devices, ensure the new device has the same serial number from Nimble. 



  8. If it matches, then create the new datastore in vSphere by clicking on the appropriate array and clicking New Datastore...


  9. Enter the details, and then rescan storage devices on the other host (if the new LUN has been added to MRS, rescan RLA) the new LUN should then show its replication LUN in the other host.

  10. Move the replication LUN to the appropriate folder.
