Error description

  • During a BACKUP VM process, the Spectrum Protect client can
    crash if the VMVSTORTRANSPORT option is not explicitly defined
    in the data mover's options file AND a virtual machine backup
    error occurs.
    
    A VM error is defined as an error seen during the processing of
    a virtual machine.
    This could be following, but is not limited to these:
    
    ANS0361I DIAG: The VDDK Utility Thread may be hung processing
    another request.
    ANS0361I DIAG: Waiting up to another 3600000 milliseconds to
    process a request to VddkFullVMCloseVMDKs for vm 'my-vm'.

    Initial Impact: Medium

    Data Protection for VMware. In Data Protection for VMware
    environments, the Backup-Archive Client is also known as the
    data mover.
    
    This problem also affects IBM Spectrum Protect for Virtual
    Environments: Data Protection for VMware 8.1.0. If you are using
    Data Protection for VMware 8.1.0, refer to APAR IT20061.
