VMWARE_VMOMI1

This error can occur in multiple scenarios.

Error Message	Resolution
Snapshot of VM failed [Problem in VM configuration.]	If this error is displayed, perform the following steps to ensure there is no problem with the target virtual machine: Manually take a snapshot using vSphere client or by web client with help of following steps: Unselect the snapshot virtual machine's memory option. Select the Quiesce guest file system option if quiescing is enabled on the Druva virtual machine backup policy. OR Unselect the Quiesce guest file system option if quiescing is disabled on the Druva virtual machine backup policy. For Windows virtual machine, check if the Virtual disk service is on. For more information see, QUIESCING-ERROR” in vCenter Server. Check if there is any third party VSS provider registered on the virtual machine. For more information see, Cannot create a quiesced snapshot of a virtual machine. Related KB article See, VMware KB 1007696
Snapshot of VM failed[Another snapshot of VM might be in the progress.]	Wait for the old snapshot to complete and trigger another backup/restore request.
Snapshot of VM failed [The number of levels in the Snapshot tree exceeds the supported maximum limit.]	Consolidate or delete the old snapshot and retry the operation.
Snapshot of VM failed[The VM is in invalid state to take snapshot.]	To resolve the error: If virtual machine is invalid or orphaned then a snapshot of such virtual machine not supported. If current power state of virtual machine is not supported to take the snapshot. You can change the power state of virtual machine. (Power off/ Power on virtual machine) and retry the operation.
Snapshot of VM failed[Incompatible device are present on VM.]	A backup fails if the Small Computer System Interface (SCSI) Controller is in sharing mode. This is because VMware does not support snapshot of virtual machines that are in bus-sharing mode. Ensure that the SCSI mode is not set to bus-sharing. For more information, see the troubleshooting section.
Snapshot of VM failed[Permission to perform this operation was denied.]	Check for the privileges.
Snapshot of VM failed[An error occurred while quiescing the virtual machine. Please retry the backup/restore again.]	Install or update the VMware tools on the virtual machine and retry the operation. Related KB article See, VMware Backups fails with error VMWARE VMOMI1
Snapshotof VM failed [Current license or ESXi version prohibits execution of the requested operation.]	Check the vCenter, ESXi version and the license details. You must use the version of the vCenter and ESXi that are supported by Druva. For more information, see Support matrix. Related KB article See, How to verify whether the ESX/vSphere host is licensed for vStorage APIs

VMWARE_VMOMI5

Error Message	Error Description	Resolution
Create new operation failed[Host capability max supported VMs is exceeded]	This error can occur if the ESX host has reached the maximum number of supported virtual machine and you are trying to add/create new virtual machine.	To resolve the error: Delete at least one virtual machine and retry the restore request. OR Try to restore the virtual machine to other ESX hosts.
Create new VM operation failed. [The virtual machine version is not compatible with the version of the host <IP address of the host>]	This error can occur if a virtual machine is backed up from a host is incompatible with the host it is restored on. For example, if a virtual machine is backed up from vCenter 6.7, the restore fails if it is restored to vCenter 6.5.	To resolve the error, restore the virtual machine to a compatible host.

Error Message:Internal error [Snapshot Task is timed out]

Error Description:This error can occur during a backup when a VM snapshot takes longer than one hour to complete.

Resolution:Some of the reasons why a VM snapshot takes a longer time to complete are:

VM tools are not installed.
VM tools support VSS as the snapshot provider for Windows VMs, but the updated version of VMware tools needs to be installed with VSS support and configured.
Disk I/O issues of the VM.

You must retry the backup once you have resolved the above issues.
