IT23320: RESTORING A SINGLE DISK INTO AN EXISTING VM COMPLETES SUCCESSFUL BUT NO DATA IS RESTORED

Download Information: Version 8.1.4.x Data Protection for VMware

APAR status

• Closed as program error.

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'

  'VMNAME'.  The restore operation continues.

  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 for Virtual Environments: Data Protection
  for VMware version 8.1on Windows x64 and Linux x86 platforms.
  
  This problem also affects IBM Spectrum Protect Backup-Archive
  Client which is the data mover for Data Protection for
  VMware 7.1. If you are using Data Protection for VMware
  7.1 refer to APAR IT22561.

Local fix

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