IT22273: ANS0323E PARTIALOBJOFFSET VALUE FOR PARTIAL OBJECT RETRIEVE IS INVALID ERROR WHEN RESTORING A VMWARE VM.

Download Information: Version 8.1.4 IBM Spectrum Protectâ„¢ for Virtual Environments

APAR status

• Closed as program error.

Error description

• Restore of a VMware guest can fail with the following error:
  ANS0323E partialObjOffset value for partial object retrieve is
  invalid.
  This restore failure can occur when the following conditions
  existed when the backup of the VM was performed:
  - ASNODE option was in use
  - COMPRESSION was set to YES
  - DEDUPLICATION was set to NO
  In this situation the backup data should not be compressed, but
  it is.
  The following message will be logged in the error log at the
  time the backup was performed:
  ANS4164W Compression is currently enabled, but the virtual
  machine backup for 'VM000001' is not compressed because
  client-side deduplication is not being used.
  The backup summary statistics will show that the objects were
  not compressed, however, this is not accurate.
  ANE4968I (Session: 281796, Node: VM000001) Objects compressed
  by:                        0% (SESSION: 281796)
  ----------------------------------------------------------------
  Customer/L2 Diagnostics:
  Review the error or schedule logs for occurrences of the
  ANS4164W message.
  Collect a client trace using the SERVICE trace flag, review the
  data for instances of objects which show  compressType=1 and
  clientDeduplicated=0.
  
  Initial Impact:
  High
   Versions Affected:
  IBM Spectrum Protect for Virtual Environments: Data Protection
  for VMware 8.1.0 and higher on Microsoft Windows and Linux
  

Local fix

• Ensure that client deduplication is enabled when client
  compression is enabled.

  Additional verification is implemented to check previous backup
  and new backup after completion.
