Error description

• Tivoli Storage Manager B/A Client may not detect timeout error o
  
  For example,  although timeout occurs during the VSS freeze
  operation, Tivoli Storage Manager B/A Client logs "rc = 0" due
  to the incorrect timeout handling, as below.
  
  yyyy-mm-dd hh:mm:ss.fff : ..\..\common\vm\wsops.cpp( 547):
  WsGuestOperations::ReadEnvironmentVariable(): Environment
  variable 'Initializing'
  ....
  yyyy-mm-dd hh:mm:ss.fff : ..\..\common\vm\acm.cpp( 807):
  ACM::Freeze(): EXIT, rc = 0
  
  Therefore, Tivoli Storage Manager B/A Client may try to take
  snapshot , despite the virtual machine is not ready.
  As result, backup vm ended with the following error messages
  which do not mean timeout in dsmerror.log.
  
  yyyy-mm-dd hh:mm:ss ANS9365E VMware vStorage API error for
  virtual machine 'VM-name'.
