IT12013: DATA PROTECTION FOR HYPER-V RESTORE VIRTUAL HARD DISK (VHD) WITH INCORRECT SIZE FROM FIRST INCREMENTAL BACKUP UPON RESIZING VHD

IBM Spectrum Protect client 7.1.4.x interim fix downloads

APAR status

• Closed as program error.

Error description

• When Tivoli Storage Manager/Spectrum Protect Data Protection for
  Hyper-V is used to restore the first incremental backup of a
  guest after resizing one or more virtual hard disks of the guest
  the disks are restored with the size recorded in the previous
  backup instead of the correct size. The restore will be marked
  as successful without any errors.
  
  All virtual hard disk restores from the second backup and
  subsequent backups after resizing one or more virtual hard disks
  and after resizing the virtual hard disks will restore with the
  correct size.
  

Local fix

• None. A workaround is available.
  
  Use the Tivoli Storage Manager/Spectrum Protect Recovery Agent
  to mount the disks of the first incremental backup after
  resizing as iSCSI disks.  In Windows Disk Management check the
  iSCSI mounted virtual disks are in the offline state, change to
  offline if they in the online state.  Use Hyper-V Manager to
  create a new virtual hard disk and specify the mounted iSCSI
  disk as the source to copy from.  Hyper-V Manager will create a
  VHDX from the iSCSI disk of the backup.
  
  Another alternative is to backup the guest immediately after
  resizing and before no changes made to the data in the guest;
  subsequent backups will restore with the correct size.
