7.4 Installation upgrade problem UPGCRC01 mitigation utility
(July 2025)
When upgrading to z/VM 7.4, multiple errors can occur, some of which are dependent upon
the configuration of the system being upgraded. Errors that might be produced when the
INSTUPGR STAGE2 (COMMIT command is run are:
-

To avoid these errors during the upgrade process, a circumventive utility exec (UPGCRC01, currently) is
available and recommended for use as part of the upgrade process. To be effective, this utility must be
acquired and in place before the INSTUPGR STAGE2 (COMMIT command is first used. In addition,
modifications to the upgrade process $STAGE2$ $TABLE$ file are required so this utility is invoked
accordingly, at specific points, when the INSTUPGR STAGE2 (COMMIT command is run.
For details, consult the UPGCRC01 Utility setup and usage page.
If the UPGCRC01 has not been used, and one of the aforementioned errors has been
encountered, consult the z/VM 7.4 Upgrade problem
manual fix information page for actions that can be taken to mitigate an existing such
problem.
Applying RSU or other PTF service on 730 Upgraded SSI member system (February 2024)
As noted in the z/VM 730 Installation Guide, it is possible to
apply service to a first-upgraded, SSI member 730 system in an SSI
cluster, before any other member systems are upgraded. However, when
this is done, specific actions can be required for certain z/VM
components that have been updated with the applied RSU or PTF service.
The components to which this consideration applies are:
DirMaint, ICKDSF and (possibly) Language Environment (LE)
If you are planning, or actively working on, SSI cluster 730 system upgrades, review and
