The query devclass command shows the attributes of device classes.
You can, if you wish, define other device classes that use the same library. It is
entirely up to how you want to configure you environment. For example, you
could define another device class to be used exclusively for creating off-site
tapes.
If you are using a separate library or a z/OS server platform, you need to define a
separate device class.
