To define a device class, first complete the following fields and then click Finish, or click Cancel to end the task.
Enter the name of the device class to be defined. The maximum length of the device class name is 30 characters.
Select the Optical or WORM device type to be assigned to the device class.
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. |
Select the recording format to be used when writing data to media. 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. |
650MB | 650MB | Using a 650 MB 5.25-inch optical drive |
1300MB | 1300MB | Using a 1300 MB 5.25-inch optical drive |
2600MB | 2600MB | Using a 2600 MB 5.25-inch optical drive |
5200MB | 5200MB | Using a 5200 MB 5.25-inch optical drive |
Select the name of the library 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. |
value | 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 assigned to 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 maximum length of time, in minutes, to wait for a volume to be mounted.
