Error description

  • A 'RESTORE VM' operation for VM guests with incorrect backup
    images might return the following errors :
    
    ANS0324E partialObjLength value for partial object retrieve is
             invalid.
    ANS4177E Full VM restore of VMware Virtual Machine 'vmname'
             failed with RC=34 target node name=
             '<target node name>',
             data mover node name='<agent node name>'
    
    The problem was found for VM guest backups performed with the
    testflag VMRESTORE_INCVMDKSIZE.
    
    The 'RESTORE VM' error will be seen with any available VMware
    transport mode (VMVSTORTRANSPORT SAN, HOTADD,NBD,NBDSSL)
    When one backup image using the Incremental Forever backup mode
    was generated using the above testflag, and even if following
    image backups are correctly done, the 'RESTORE VM' still might
    fail.
    
    Tivoli Storage Manager Versions Affected:
    Tivoli Storage Manager Client 6.4 and later on Windows and Linux
    
    Initial Impact: High
    
    Additional Keywords: restore VMware TDP4VE corruption

Local fix

  • 1. Contact support to get the needed VM guest restored
    and
    2. Start new series of backups for that VM guest with a IFFULL
       VM backup to avoid future occurrences

Problem conclusion

  • The backup-archive client now verifies each disk before vm
    restore and if the testflag is set fixes the disk size.
    
    The error message is still issued to indicate there was
    an issue before the client fixed the disk size to restore it.
    In the future, we will consider whether a warning message
    instead of an error message would be a better design.
