IBM i Hardware Technology Refresh - Information for IBM i 7.4

This page contains information regarding the latest IBM i 7.4 Hardware Technology Refresh.

Note: Beginning in 2025, a Technology Refresh is divided into a Hardware Technology Refresh and a Software Technology Refresh.  These deliverables may be announced and delivered separately and in different quarters.  The information on this page is specific to Hardware Technology Refreshes and is not applicable to Software Technology Refreshes.  Additional information is available on the Overview page.

¹All dates are shown in MM/DD/YYYY format

²Detailed description of Technology Refresh content can be found in IBM Developer, under IBM i Technology Updates Hardware and Firmware.

The description of the Hardware Technology Refresh.

This identifies the vintage of the Hardware Technology Refresh PTF Group. This is a PTF Group that contains a Hardware Technology Refresh PTF for a particular GA, plus related PTFs, including the most recent pre-GA fixes. In general, the Hardware Technology Refresh PTF Group should be installed rather than the individual 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 Hardware Technology Refresh. The Resave contains the hardware 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 Hardware Technology Refresh PTF. This is a PTF for a specific release / VRM. IBM identifies the Hardware Technology Refresh PTF level for 5770-999 by a set of reserved PTF numbers: MF993xx, with high digits indicating more recent Hardware Technology Refresh PTFs. Later PTFs for a particular release are supersets of previous Hardware Technology Refresh PTFs for that release, and systems may have more than one Hardware Technology Refresh PTF installed. Later versions of the Hardware Technology Refresh PTF for a release will supersede previous versions. The currently active version of a Hardware Technology Refresh PTF on a system is the PTF with the highest MF993xx PTF ID in applied status.

To determine the Hardware 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 Hardware Technology Refresh PTF Group (not just the latest PTF) installed on your system.

To determine the Resave level of 5770-999, do a Display PTF function for product 5770-999. Marker PTFs for this product are in the format of REnnnnn. The highest number Marker PTF on your system, matched with the table above, indicates the Resave level for this product.

To determine the Hardware Technology Refresh PTF level of 5770-999, do a Display PTF function for product 5770-999. Hardware Technology Refresh PTFs for this product are in the format of MF99nnn. The highest number PTF on your system, matched with the table above, indicates the Hardware Technology Refresh level for this system.
