I would say 3990 is more likely to be correct. You cannot force the device to be a 2105 if it isn't. These are sensible devices (not my pun) that tell the OS what you have there. But there may be magic spells that IBM software does to IBM hardware in the initialization phase, and you may be messing things when not everyone found already that your were cheating. The EMC folks used to do things in the configuration to make the box appear like one or the other. I recall an event in the past where a simple firmware upgrade (with different defaults) made VSE fail to run on the device. Many of these tweaks are just there to fool SMS policies in z/OS. If anything is able to fool the system in thinking this is a 2105, then it would be there. Whether that is enough to serve as a test for going to real D/T2105 depends on your standards and your relation with EMC and/or IBM. As others said, INSTALL does not apply to modern DASD (it deals with alignment after the folks bumped the DASD off the truck). INIT is not done for VM DASD either. Rob
