Error description
The Virtual Machine (VM) guest backup might fail with the following messages: ANS0361I DIAG: VmWaitBackupDoneAndStopMovers(): Deadlock detected on process backup VM 'vm_name'. No disks finished backing up or data sent to server in last 70 minutes. ANS4174E Full VM backup of VMware Virtual Machine 'vm_name' failed with RC=7305 mode=Incremental Forever - Incremental, target node name='node_name', data mover node name='node_name' ANS1228E Sending of object 'vm_name' failed. ANS9373E The backup of virtual machine 'vm_name' stopped because the backup operation was not progressing. This issue is reported when backing up a VM guest that includes multiple disks. The cause for the errors is a failure to backup one disk while the other disk's CTL files are still being processed. The datamover attempts to stop the backup and this action results in a deadlock detected message being incorrectly reported. IBM Spectrum Protect Versions Affected: IBM Spectrum Protect for Virtual Environments - Data Protection for VMware version 8.1.x and later on Windows and Linux. Additional Keywords: TS005642945, deadlock, RC=7305
