Cause
There are several settings that may cause this issue. See the settings below in Resolution.
Resolution
1. Check the DRS setting for Virtual Machine Automation that it is enabled. (VxRail cluster -> Configure -> vSphere DRS -> Edit)
2. Check VM Overrides entries (VxRail cluster-> Configure-> VM Overrides).
3. If a VM is found in the VM Overrides entries, check the corresponding vSphere DRS automation level. It is "Disabled" or "Manual," which is preventing DRS from automatically migrating the VM. Check if the VM entry can be deleted.
5. If the entry cannot be deleted, set the DRS automation level for the VM to "Fully Automated." This enables DRS to automatically migrate the VM.
