Hum, Under LPAR or z/VM, I would have thought that would be "transparent" due to the "Physical CP" to "Logical CP" mapping done by them. Also, 99% of the time, when a CP fails, the hardware automatically switches to a spare CP (if there is one) with no OS intervention at all. I think that the OS gets some sort of interrupt so that it can record the error, but no error recovery is required by the OS in this case. We had this occur on a z800 running z/OS 1.4. Nobody even noticed until I went into the NOC and saw the "Hardware" ICON flashing blue. The NOC people pay very little attention to the z800. Only if there is a visible problem with some job or somebody else calls them. They're too busy watching all the Windows boxes. -- John McKown Senior Systems Programmer UICI Insurance Center Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its' content is protected by law.
