This identifies the vintage of the Technology Refresh PTF Group. The Technology Refresh PTF Group is a PTF Group that contains a Technology Refresh PTF for a particular GA, plus related PTFs, including the most recent pre-GA fixes. In general, the Technology Refresh PTF Group should be installed rather than the individual Technology Refresh PTF. A higher PTF group level number indicates a more recent group. Only the most recent version of a PTF group is available to be downloaded or ordered.

This identifies the 5770-999 Resave level that corresponds to this Technology Refresh. The Resave contains the technology refresh plus related code, including fixes. The name of 5770-999 Resave contains the VRM plus a letter to indicate the Resave level, e.g., RS740-A, RS740-B.

The marker PTF is a PTF that can only appear on a system if it was installed with an IBM supplied Resave. These markers are cumulative, meaning systems may have more than one of the Marker PTFs available. The highest Marker PTF number found can be used to determine what Resave level of the product is installed. The Marker PTF refers to the Resave Level, not the Technology Refresh Level.

This identifies the vintage of the Technology Refresh PTF. A Technology Refresh is a PTF for a specific release / VRM. IBM identifies the Technology Refresh PTF level for 5770-999 by a set of reserved PTF numbers: MF993xx, with high digits indicating more recent Technology Refresh PTFs. Later Technology Refresh PTFs for a particular release are supersets of previous Technology Refresh PTFs for that release, and systems may have more than one Technology Refresh PTF installed. Later versions of the Technology Refresh PTF for a release will supersede previous versions. The currently active version of a Technology Refresh PTF on a system is the PTF with the highest MF993xx PTF ID in applied status.

To determine the Technology Refresh PTF Group level installed on a system, do a Work PTF Group function. Find the PTF group named SF99737. There may be multiple different levels of the group installed on the system. The latest level (the one with the highest level number) with the status of Installed is the current level of the fix group that is active. It is a best practice to keep the latest level of the Technology Refresh PTF Group (not just the latest Technology Refresh PTF) installed on your system.
