Error description

  • Restoring a singledisk (e.g. hard disk 2) into an existing VM
    requires that a disk with the same label and the same capacity
    exists in the Virtual Machine configuration where the disk is
    being restored.
    While the restore currently completes successfully without
    actually restoring any data, this operation should fail.
    
    Example:
    
    tsm> restore vm "VMNAME:vmdk=Hard Disk 2"
    Restore function invoked.
    Restore VM command started.  Total number of virtual machines to
    process: 1
    Restore of Virtual Machine 'VMNAME' started
    Starting Full VM restore of VMware Virtual Machine 'VMNAME'
    target node name='VMWARENODE', data mover node
    name='VMWARENODE_DM'
    
    Virtual machine: 'VMNAME' disk: 'Hard Disk 1' is excluded from
    restore by user.
    Restoring VM configuration information for 'VMNAME'
    ANS2145W Warning - updating an existing virtual machine named
    'VMNAME'.  The restore operation continues.

    Total number of bytes transferred:            0  B
    Data transfer time:                        0.00 sec
    Network data transfer rate:                0.00 KB/sec
    Aggregate data transfer rate:              0.00 KB/sec
    Elapsed processing time:               00:00:15
    
    Note the successful restore of the VM, while no data was
    restored.
    
    This restore should
     - Change the restore summary to a failed restore operation.
     - Have a message stating that the disk that is being restored
    must exist in the Virtual Machine.
    
    Documentation also needs to be enhanced to document the
    requirement that the disk being restored must exist in the
    Virtual Machine.
    
    Products affected:
    IBM Spectrum Protect Backup-Archive Client version
    7.1 and higher on Windows x64 and Linux x86 platforms.
    Note: The Backup-Archive Client is a prerequisite to using the
    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. If you are using
    Data Protection for VMware 8.1, refer to APAR IT23320

Local fix

  • Create a disk with the same label and the same size in the
    Virtual Machine and try the restore again.
