Updating a ZVM to Support Zerto-Approved Host Releases Prior to a Full ZVR Update

KB Number:
000001024

Symptoms:
Zerto implemented a means for customers to update the list of Zerto-certified vSphere\Hyper-V host builds supported for Zerto Virtual Manager (ZVM) installations.

This way, customers do not have to wait for the next official ZVR release for the new vSphere ESXi\\Hyper-V Host version to be supported.  Assuming the necessary connectivity is available between the customer ZVM and vCenter\\SCVMM, this list will be updated automatically at midnight ZVM-time, following Zerto's certification of a new ESXi\\Hyper-V host version.

In the event that the necessary connectivity does not exist, the list of Zerto-certified ESXi\\Hyper-V Host versions supported for customer ZVM installations can be updated manually.  This article explains the necessary process.

Cause:
ESXi\Hyper-V Host releases

Solution:

In order to update the list of Zerto-certified ESXi versions, follow these steps:

  • Contact Zerto Support to ensure that the ESXi\\Hyper-V Host version you want to use is certified and supported by Zerto.

  • Navigate to the Zerto Virtual Replication directory on the ZVM, based on the version of Zerto you are using:
    3.0 - 4.0 - The default directory is 
    C:\\Program Files(x86)\\Zerto\\Zerto Virtual Replication.
    4.5 - The default directory is C:\\Program Files\\Zerto\\Zerto Virtual Replication

  • Locate the 'supported_updates.txt' file, and copy it to the desktop for a backup.

  • Edit the 'supported_updates.txt' file in the Zerto Virtual Replication directory, and add the necessary string, on a new line in sequence with the other strings, with the following syntax:
    ESX_<VersionNumberWithoutPeriod> <Update Number>
    User-added image

  • Save the file.
  • Access the Zerto GUI for the relevant site (If the Zerto GUI was already opened, please refresh the page).
  • Click the Site Configuration "cog” (3.5 and earlier) or “menu” (4.X and later) button > "Advanced Settings" > "Compatibility Matrix".
  • Verify that the new Zerto-certified ESXi version is listed.

 
            Notes:

  • If the file already contains an ESX version string listed with the same version number, but a different update number, replace it with the new update. For example, if the version to be added is vSphere 5.5 Update 1, and ESX_55 0 is listed, replace it with ESX_55 1.
  • Do not add any extra white spaces for the new entry in the 'supported_updates.txt' file, as this file is very sensitive to white spaces.
  • If a VRA has already been installed on a host with the new ESXi version, after the automated or manual change to the list of Zerto-certified ESXi versions, the VRA that previously showed a status of "Unsupported Version" will automatically enter a supported state.

 
If any issues are encountered, please contact Zerto Support.
