IT02276: THE PASSWORD FILE TSM.PWD MIGHT GET DELETED WHEN MULTIPLE SESSIONS TRY TO UPDATE PASSWORD AT THE SAME TIME

IBM Tivoli Storage Manager (TSM) Client 7.1.2 Downloads and READMEs
IBM Tivoli Storage Manager Client 6.4.3 Downloads and READMEs

APAR status

• Closed as program error.

Error description

• In a scenario where two separate sessions are established to the
  Tivoli
  Storage Manager server at nearly the same time, and the password
  for this client node has expired, both sessions will be forced
  to perform a password change.
  The first session will update the password and perform password
  verification.
  Then, when the second session also updates the password, the
  server will return error:
  
  RC6 = DSM_RS_ABORT_BAD_VERIFIER.
  
  When the client receives this RC6, the password file TSM.PWD
  will be
  deleted when this entry is the only or last entry in the file.
  
  This problem may happen with all data protection products that
  use the Tivoli Storage Manager Application Programming Interface
  (API).
  It was initially reported in apar IC92058,  but the solution was
  not sufficient for
  large environment with many parallel sessions which try to do
  the password expiration at near the same time.
