Class Name:
CRmsDriveClass
Class Description:
A CRmsDriveClass holds administrative properties associated with a drive, more
typically a grouping of drives that are of equal performance characteristics,
and capabilities. These properties include current mount limits, and Cartridge
idle time specifications that indicate when an inactive Cartridge should be
returned to its storage location.
By default a DriveClass object is created for each type of media supported by
the drives in a library. Multi-functions drives will be associated with multiple
drive classes.
A DriveClass maintains a collection of drives that are associated with the DriveClass.
