We're working on it, but as you can imagine there's a lot of old, crufty code that makes assumptions about the number of devices in use, so it's not going to be here soon. Work is underway with a new Changer API that does implement locking and permit simultaneous use of multiple devices. This will be used initially for a basic kind of "data vaulting" (copying dumps from one set of volumes to another), where the source and destination volumes may both be accessed by a changer. The new API hasn't hit trunk yet, as I'm still discovering flaws and bugs, but I'm happy to share what I have if anyone is interested. Dustin -- Storage Software Engineer http://www.zmanda.com
