Sorry sent too quick. If you want to continue to use this method I would change the mail system to use volumes 4506-450D and then use 4701-4708 as the flash copies and then VM will always grab 4506-450D.

One is that the VM system got reIPLed and grabbed the 4506-450D volumes because they had the correct volser and were the 1st one found. If the system did not get reIPLed then somehow something (FDR?) released volumes 4701-4708 from the system and attached volumes 4506-450d to the system. This is normally done by the following commands DET 4701 SYSTEM and ATTACH 4506 SYSTEM.

Volumes are full-pack volumes and are dedicated to the VM guest when we autolog the guest. Dedicates are in the form of "DEDICATE 1500 VOLID xxxxx". This has worked well for us. For backing this system up, we use FDR from the z/OS side to backup. Of course, the linux system is down when we do this so we can get a clean copy. Since we're using 8 3390-27's to hold our mail files, our backup window is about 2 hours. In an effort to reduce the size of the window, we used FDR to Flashcopy these volumes to other DASD. And then backup these DASD. My understanding is when using FDR to flashcopy, it will change the VOLSER for the target devices (can't vary them online to z/OS). Our VOLSERS are LEMAI1 - LEMAI8. Reside on units 4701-4708. Our flashcopy targets are on 4506-450D. This scenario worked for several weeks until yesterday. When we autologged the guest machines, somehow they grabbed 4506 and 4507. (I'm assuming somehow the volsers got changed?) Has anybody had any experience with doing something like this? Any idea why z/VM assigned 4506-4507? Correct me if I'm wrong, but z/VM will take the first device it finds matching a VOLSER? What can we do to remedy this? Is this even a good idea? Thanks
