Creating Volume Classes

Volume classes are used to restrict data. To create a volume class on a system or nonsystem volume set, use the NEWCLASS command.




	NOTE: The default class `DISC` is assigned to nonsystem volumes unless another volume class is specified when using the `NEWSET` or `NEWVOL` commands. Also, the master volume does not need to be a member of every volume class in the volume set.

This example shows how to create a new volume class.

To create a new class, ENGR, on the PROD_SET nonsystem volume set, use the following command at the VOLUTIL prompt:
The volume class name can be up to 32 alphanumeric characters in length. The first character must be alphabetic.
volutil: NEWCLASS PROD_SET:ENGR MEMBER1

Verify that the class has been created by using the SHOWCLASS command.

   volutil: SHOWCLASS PROD_SET:ENGR 



   Volume class index: 2

   Number of volumes in class: 1

Once a class is specified, the system recognizes the class and the class is ready for use.




	NOTE: A class cannot be deleted from the volume set. Likewise, a volume cannot be deleted from a class.
