IBM periodically releases new Resave media. Resaves are often Machine Code (57xx-999) but occasionally a Resave is made available for IBM i (57xx-SS1).
Resaves of the currently supported releases are valuable to you for several reasons.
Resaves provide:
- support for new hardware (for example, new I/O devices or newly announced models)
- critical fixes in the system install media (for example, install or IPL path fixes)
- a reduced "total install time" by reducing the time to install cumulative PTF packages
Resaves are created by PTFs being permanently applied and new install media is created. Each Resave goes through significant install and regression testing to ensure optimal system quality.
Situations where a customer should use the Resave media include:
- when a new partition containing newly purchased hardware is to be installed
- when preparing to upgrade to new processor models or features
- when using an alternative IPL device for recovery for new processor models or features
To determine the minimum Resave levels needed for hardware refer to the IBM Prerequisite tool.
