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.
Example: Creating a Volume Class
This example shows how to create a new volume class.
1. 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 |

2. 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.
