ABSTRACT:
An archive command detects an original storage device density value from the device and changes the device's density to a ROM density required by system ROM to read a bootstrap image. The bootstrap image from the system, as well as the original density value stored in a density file, are then written to the storage media in the ROM density required for system restoration by the IPL. The system then reads its copy of the original density value, changes the storage device parameters to their original value, and writes the desired additional system image or other software to the device media in the original device density. When restoration of the thus-archived bootstrap image or other software is required, during system IPL the system ROM will read the bootstrap file from the media stored in the correct ROM density required by the system ROM. When IPL and the bootstrap program have completed booting the system to a minimal state, a restoration program built as part of the bootstrap image then commences restoration. The restoration reads the original device density parameter stored in the media in the density file, changes the storage devices parameter to this value, and proceeds to read into the system the remaining system image or other software on the media, which was stored in the original density, thereby completing restoration.
