To define a device class for storage pools, 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.
Select the recording format to be used when writing data to media. The default is Drive.
Note: This format uses the tape drive hardware compression feature. Depending on the effectiveness of the compression, the actual capacity may be greater than the listed value.
Format | Estimated Capacity | Description |
Drive | Determined by drive capacity. | The server selects the
highest format that can be 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. |
8200 | 2.3GB | Uncompressed (standard) format, using standard 112-meter tape cartridges |
8500

See note above.

Drives (Read Write)
Eliant 820 (RW) |
8700 | 7.0GB | Uncompressed (standard) format, using standard 112-meter tape cartridges |
20GB | 20GB | Uncompressed (standard) format, using standard 112-meter tape cartridges. |
Select the name of the defined library object that contains the 8mm tape drives used by this device class.
Enter the maximum number of volumes that can be simultaneously mounted for the device class.
Enter the amount of time, in minutes, to retain an idle volume before dismounting it.
Enter the high level qualifier of the file name that the server writes into the media labels. For each volume assigned to this device class, the server uses this prefix to create the data set name.
Example: AB.CD2.E
Enter the estimated capacity for the volumes assigned to this device class. This parameter is optional.
You can specify this parameter if the default estimated capacity for the device class is inaccurate due to compression of data.
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.
