It used to be recommended that certain primary and alternates be flip-flopped over two volumes. I have always believed they should be spread over more than two. Also, I have never understood why there is so much I/O to disk with CF's being around. I implemented my first SYSPLEX in 1994, and I never got an answer to that question -- other than 'because'. - Too busy driving to stop for gas! ---------------------------------------------------------------------- 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
