Yes, that reference looks very close to what I want to do. It has been drummed into me with the replies and documentation that a set of two parallel GM sessions from the same source volumes (H1) to two other sets of volumes (H2 and H3) is just not supported.
I have developed a new Idea and I could use some feedback. How does this sound? 1. A Metro Mirror within a single DS8k Where set H1 clones to H2. 2. Establish a second Global Mirror from H2 to the new DS8900F - H3 This is close to the Metro/Global Mirror scenario in the documentation. It just moves the H2 target from a 3rd DS8k into the H1 DS8k. There are potential pitfalls that need more research 1. Can H2 be Space Efficient volumes in a Internal Metro Mirror or do they have to be fully configured for space? 2. Can the H2 be both the target of a MM *and* the source of a GM relationship? 3. Does this expose us to buying additional capacity licenses for the Copy Services license? Fancy technology breeds fancy problems. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
