How to apply different version of VDDK other than the built-in Version in Arcserve UDP

VMware Virtual Disk Development Kit (VDDK) 6.5 is built-in with Arcserve UDP v6.5. At the same time, Arcserve UDP v6.5 is compatible with VDDK 5.5.5. If you want to perform VSB/Instant VM/Assured Recovery to VMware 5.0 or 5.1, use VDDK 5.5.5 instead of VDDK 6.5.

Important! Arcserve certifies only VDDK 6.5 and 5.5.5 . Other versions of VDDK are not guaranteed to work with Arcserve UDP Version 6.5.

You can modify VDDK manually or by using Windows batch file. This topic explains procedures for both the options.

Considerations:

• For Instant VM and Assured Recovery Test, you need to perform this action on Recovery Server/Proxy Server.
• For VSB to VMware, use a dedicated Agent server as VSB monitor and configure the VSB task in proxy mode. Then, manually switch the VDDK to version 5.5 on the VSB monitor server.
• If the VSB task is configured in an MSP plan or a cross-site plan switch the VDDK on the RPS server as the monitor server is not present. As a result, this RPS server is not available to use as a proxy server for Host-Based Agentless backup task.

To change the VDDK manually, follow these steps:

1. Log into the computer where the Arcserve UDP Agent is installed using an administrative account or an account that has administrative privileges.
2. Rename the folder VDDK to VDDK6.5.
3. Rename the folder VDDK5.5 to VDDK from the following default location:
4. C:\Program Files\Arcserve\Unified Data Protection\engine\BIN
5. Note: The location of the BIN folder can vary depending upon the location where you installed the Arcserve UDP Agent.
4. Run the following command to verify the state of the service:

Note: You need to delete the service, only when not in running status.

sc query vstor2-mntapi20-shared

If the service does not exist, delete using the next step. If the service is running, before deleting using the next step run the following command to stop:

sc stop vstor2-mntapi20-shared

5. Run the following command to delete the service:

sc delete vstor2-mntapi20-shared

6. Run the following command to verify if the service is deleted successfully:

sc query vstor2-mntapi20-shared

Note: If the state of the service is STOP_PENDING, restart the machine.

To change the VDDK using a Windows batch file, follow these steps:

1. Log into the computer where the Arcserve UDP Agent is installed using an administrative account or an account that has administrative privileges.
2. Launch the ChangeToVDDK55.bat utility tool from the following default location:

C:\Program Files\Arcserve\Unified Data Protection\engine\BIN

3. Note: The location of the BIN folder can vary depending upon the location where you installed the Arcserve UDP Agent.
4. VDDK 5.5 is installed after a new job is launched.
