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.
