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
