CBU is not used at the DR site because at the DR site (3rd party provider), I get an equivalent of the MIPS (MSUs) which I am running at my local site. So indeed I am restricted to what is considered a non-DR event at the local site. A DR event locally is one where both of the z9BC's or something like all my DASD blowup, hey a flood in the basement, etc. In general if one z9BC "smokes bigtime" and it can not be replaced within a reasonable amount of time, then I can invoke CBU on the other z9BC to bring one from an IBM 2096-O02 to z02 or IBM 2096- T03 to a z03 and all for less than $6K per year if my memory serves me. If one can afford GDPS and your own second site, then am sure one can afford to pay a few dollars more to invoke CBU at a DR site. jim ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
