Error description

  • If the VMVSTORTRANSPORT option has more than two methods
    specified, the VM backup may fail if the first VMVSTORTRANSPORT
    method fails.  The Tivoli Storage Manager Client will attempt to
    use the second method, but may ultimately fail.
    Dsmerror.log will show the following:
    ANS1711W Incremental backup selected for 'vrdmtest', but a Full
    backup has not yet been performed. Performing a Full backup
    instead.
    ANS1228E Sending of object 'vrdmtest' failed.
    ANS5283E The operation was unsuccessful.

Local fix

  • Limit VMVSTORTRANSPORT option to no more than two preferred
    methods.

Problem conclusion

  • Current implementation had some logical errors and,
    as result, VMVSTORTRANSPORT option was not hadled
    properly in case when more than two preferred
    transport modes were specified in it.
    
    The code has been changed so that any number of
    preferred transport modes can be specified now.
