Error description

• After upgrade to Datapower version 7.0.0.14, 7.1.0.11, 7.2.0.8
  or 7.5.0.2, requests may fail with RSA signature failure even
  though the HSM is properly initialized.
  example:
  [0x80600047][crypto][error] mpgw(TP_XA): tid(1959047)
  [request][10.1.0.0] gtid(1959047): *RSA signing failed*
  [0x80600157][crypto][error] wsgw(TP_XA): tid(1959047)
  [request][10.1.0.0] gtid(1959047):
  Signature generation failed: *RSA signing failed*
  
  This is caused by the HSM upgrade to version 2.2 introduced
  with APAR IT15555.
  

Local fix

• Downgrade HSM version to 1.2 as described at
  http://www.ibm.com/support/docview.wss?uid=swg21984581.
