Well, I just stumbled about this again (and I don’t know right now whether or not this is documented inside a RedBook or not) today, so I thought maybe I’m gonna write it down.
Please keep in mind, when creating the virtual library to think hard about the amount of slots you might need. It ain’t that bad, you just can’t decrease the amount anymore. So if you think about creating 50 different virtual tape libraries with 500 slots each on your TS7530, think again. The current software level only supports 25.000 slots on a global level.
