Error description

• Backup fails if  Tivoli Data Protection (TDP) for Hyperv host
  system
  is Windows 2012R2 and  it runs out of available mount points
  during a backup operation by exceeding the maximum number of
  mount setting on the TSM Server,
  
  Multii-session backup for the TDP for HyperV client requires
  multiple mount points to be available on the Tivoli Storage
  Manager server.  If a mount point isn't available, the backup
  will fail.  With TDP for HYPERV, instead of
  failing, we retry the backup .  However, on Windows
  2012 R2 Update 1 instead of retrying, the backup will simply
  fail.
  
  See TSM Client documentation that describes  retry after
  exceeding
  MAXNUMMP here:

  bm.itsm.client.doc/r_opt_vmmaxparallel.html?lang=en
  

Local fix

• Workaround: Set up MAXNUMMP as documented in the TSM Server
  documentation.
  
  See update node MAXNUMMP in the following documentation.

Problem conclusion

• The problem is fixed, retried backups due to insufficient node
  mount points of Hyper-V virtual machines will succeed in Windows
  2012 R2 with Update (KB2919355).
  

Temporary fix

• Tivoli Storage Manager Client on Windows 7.1.2.1
  Note: Until a Data Protection for Microsoft Hyper-V packaged fix
  of a fixing TSM Client level is available, Data Protection for
  Microsoft Hyper-V customers can install and use a fixed level of
  the the TSM Client in their environment.
