To define a device class, first complete the following fields and then click Finish, or click Cancel to end this task.
Enter the name of the device class to be defined. The maximum length of this field is 30 characters.
Select an option. This parameter is required.
Optical | Specifies that the device class uses two-sided 5.25 inch rewritable optical media. |
WORM | Specifies that the device class uses two-sided 5.25 inch write-once read-many (WORM) optical media. |
WORM12 | The WORM 12 device type is only valid on AIX 4.1.4 or subsequent systems. |
WORM14 | The WORM 14 device type is only valid on AIX 4.1.4 or subsequent systems. |
Select an option. This parameter is optional. The default is Drive.
Format | Estimated Capacity | Description |
Drive | Determined by drive capacity. | The server selects the highest format that is supported by the drive on which
a volume is mounted.
Avoid specifying DRIVE when a mixture of drives is used within the same library. For example, do not use this option for a library containing some drives that support recording formats superior to other drives. |

Select the name of the defined library object that contains the optical drives used by this device class.
Enter the maximum number of volumes that can be simultaneously mounted for the device class. The default is Drives.
The following are possible values:
Drives | Specifies that the server determines the mount limit based on the number of drives defined and online in the library. |
number | Specifies the maximum number
of drives used concurrently. This value can be any number from 0 to 256.
This value must not be allowed to exceed the number of drives defined and online in the library. For external libraries, specify the number of drives for the library. |
0 | The value of zero prevents new transactions from gaining access to the storage pool. |
Enter the amount of time in minutes to retain an idle volume before dismounting it.
Enter the estimated capacity for the volumes categorized by this device class.
You do not need to specify an estimated capacity unless the drives perform data compression, or you have volumes of nonstandard size.
The value must be an integer followed by one of these units:
K | Kilobyte |
M | Megabyte |
G | Gigabyte |
For more information on the default estimated capacity, see the Recording Format heading.
Enter the length of time, in minutes, to wait for a volume to be mounted.
