I know that I did not dream it. I strongly suggest that your do your DR under z/VM. It makes things so much easier. However, if you cannot do this, then you can have another z/OS IODF which matches your DR provider's setup. With Comdisco, and now Sungard, they supplied the basic IODF to us. I would then make another one from it which had our ESOTERICS and consoles defined. At DR, we would user the LOADxx member which pointed to the IODFCD, as I called it. -- John ---------------------------------------------------------------------- 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
