Error message in activity log
Deploying plan 'Plan name' for node 'node name', assign plan failed.
Unable to apply 'plan' to proxy 'node name'. (The Arcserve UDP Agent web service on the proxy 'node name' is busy. Retry later. )

Description: Hyper v Hbbu agentless backup plan fails to deploy when we have many nodes. Normally this is caused if the proxy is too busy to response before timeout.

There could be multiple reasons why the proxy could be busy. When we mention proxy is busy it means that the UDP agent present on the server which is used as proxy for agent less backup is busy. It could be that the same server is used for other things as well such as it would be rps server ,Virtual standby converter or console server. If more thing are been given on the same server which would eventually use the UDP agent it may result in busy state. This may again vary from setup to setup

Solution :-

Deploy plan in a smaller batch (default is 50 nodes) so that deployment can finish before  timeout.

Steps to follow:-

1. Log on UDP console machine,
2. Go to C:\Program Files\Arcserve\Unified Data Protection\Management\Configuration, and locate the file ConsoleConfiguration.xml. [default installation path for the arcserve UDP]

Attached screenshot for reference:

3. Edit this file and change the value of tag <maxDeployVMCountEachTime>. Default is 50, change to a smaller number like 10 or even 5.

Screenshot for reference:

4. Save the file.

5 . Restart UDP management service.
