John, Somehow I have it stuck in my mind that the VARY command just works at the OS level, varying devices online or offline to z/OS but nothing else. Using the CONFIG command actually changed the configuration in the I/O subsystem or other areas that are closer to the hardware. I'm probably wrong with this but that's what I remember.

In the deep, dark, past, I remember that we used the VARY command to change the status of things such as storage, CPs, and channels. Now, some things such as DEVICES are manipulated via the VARY command whereas others, such as the CHPs, are manipulated via the CONFIG command. Anybody have any idea why? Or how it was decided which things were VARY'd and others CONFIG'd? -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
