Abstract

The problem of isolating a hardware error during disk CSIPL (Control Store Initial Program Load) is minimized by the error-isolating software within the disk CSIPL loader. The disk CSIPL loader is used to load diagnostics, the Diagnostic Control Program (DCP), and the System Support Program (SSP) into memory within a computer system. It is during the execution of the disk CSIPL loader that hardware error isolation is performed. In one prior computer system, continuous retries were made when hardware errors occurred but no error isolation was performed. In another system, an error code was displayed to indicate the load in which the hardware error occurred. No attempt to isolate where the error was occurring was implemented.
