On the S/360 the Alternate CPU Recovery facility was limited to 65MP (I don't know about 9020 or TSS/360.) On MVS it was a standard facility, although on an AP or MP without Channel Set Switching losing the processor with the I/O channels was fatal. With MVS/XA and later I/O was more robust.

Some machines are meant to allow processors to fail, be replaced, be added, and brought online while the workload continues. The SPARC Enterprise 10000 (Starfire) comes to mind. I suspect that a System 360 would have had major problems if the ""processor failed. Most Open Systems are not designed with the ability for Online Insertion and Removal of components, including processor and memory. Some are. -- Grant. . . . unix || die ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
