IT37898: VMWARE VM GUEST BACKUP FAILS WITH "ANS0361I AND VMWAITBACKUPDONEANDSTOPMOVERS(): DEADLOCK DETECTED" AND RC=7305

APAR status

• Closed as program error.

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
