Error description

• GDPSCHG MIGRATE GMMODE(NONMT2MT) sometimes does not recognize
  that PPRCMT is enabled in DEVSUPxx although it is. User gets
  NCCF message:
  GDPSCHG: PPRCMT not enabled in DEVSUPxx.
  As a result of this, the command does not remove and rejoin

  * PROBLEM DESCRIPTION:                                         *
  * The GDPSCHG MIGRATE GMMODE(NONMT2MT) command that is used to *
  * migrate from cascaded to multi-target capable GDPS MGM       *
  * versions like from GDPS MGM 3.14 with GDPS/PPRC to GDPS MGM  *
  * 4.x sometimes does not recognize that PPRCMT is enabled in   *
  * DEVSUPxx. This leads to that the command fails and the GM    *
  * relationships are left without the GM secondary information  *
  * that is needed for running the GM session from the same      *
  * source volumes as the Metro mirror session.                  *

  GDPS issues the MVS command MODIFY DEVMAN,REPORT to find out if
  PPRCMT is enabled via the DEVSUPxx member in the Kg-system. Some
  times the output is not catched by GDPS. This PTF adds more
  diagnostics to see why GDPS could not catch the output as well
  as a bypass option that the user can set to bypass the check
  (after checking himself that PPRCMT really is enabled).
  

Problem conclusion

• This PTF adds more diagnostics to see why GDPS could not catch
  the output as well as a bypass option that the user can set to
  bypass the check for PPRCMT enabled (after checking that PPRCMT
  really is enabled).
  
  To enable the extra diagnostics issue the following command
  before retrying the GDPSCHG MIGRATE GMMODE(NONMT2MT):
  VPCEDEB GDPSCHG DEBUG(2)
  And provide IBM GDPS support with the Netlog.
  
  To bypass the check:
  Issue the MVS command F DEVMAN,REPORT and ensure that PPRCMT is
  listed for "OPTIONS: ". Then issue the command:
  VPCESET VPC_BYPASS_MTCHECK YES
  to bypass the check. Then retry the
  GDPSCHG MIGRATE GMMODE(NONMT2MT)
  command.
