The virtual machine reports that it has virtual disks that need consolidation and this could not be performed automatically. In order to prevent a further buildup of delta disks and possible stability issues with the virtual machine, further backups of this virtual machine will not be performed until this condition is corrected. Please check if there are any locks on the virtual disks or if the disks are still attached to a backup proxy.

Hello
In most cases this is due to Hotadd locking the disks on the Proxy machine. Can you confirm if you are using Hotadd Transport Mode for your backups?

If you are there are few things to check here:
- -Within VMWare verify if there are any disks present on the Proxy machine(s) that do not belong to the Proxy VM
- -Within the Guest OS check is automount is enabled
- Open Command Prompt as Admin
- Go into disk part with the “diskpart” command
- Once diskpart loads type the command “automount”
- If this is enabled ensure there are No VSA backup running
- Run the “Automount disable” then “automount scub” commands
- Check AV Exclusions on the Proxies(https://documentation.commvault.com/commvault/v11/article?p=8665.htm)
