How to Update ZVM to Support Zerto-Approved Host Releases Prior to a Full ZVR Update
Viewed 1820 times
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.
**Note: This procedure SHOULD NOT be used to add support for an ESXi version that has not yet been tested and certified by Zerto. For the most up-to-date reference of supported versions please refer to our Interoperability Matrix: Interoperability Matrix for All Zerto Software Versions (latest) **
If your ESXi version is not yet on the Interoperability Matrix, please see the following article: How to Determine when to Upgrade the ESXi Version of a Host in a Zerto Environment
In order to update the list of Zerto-certified ESXi versions, follow these steps:
- Confirm with our Interoperability Matrix 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:
- 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>
- 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 “menu” button > "Advanced Settings" > "Compatibility Matrix".
- Verify that the new Zerto-certified ESXi version is listed.
- 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.**
