To update a device class, first complete the following fields and then click Finish, or click Cancel to end the task.
Select the recording format to be used when writing data to volumes in this device class.
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. The actual capacities may vary depending on which cartridges and drives are used.
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. |

Select the name of the library 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.
The following are possible values for Mount Limit:
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 in this device class by the server.
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 | 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 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.
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.
