Updating a Removable File Device Class

To update a device class, first complete the following fields and then click Finish, or click Cancel to end the task. Existing values are displayed.

Library Name

Select the library name that contains the removable media drives used by this device class.

Maximum capacity

Enter the maximum size of any volumes (which are actually files) defined to a storage pool categorized by this device class. Because the server opens only one file per physical removable medium, specify a capacity that enables one file to make full use of your media capacity.

The value must be an integer followed by one of these units:

K Kilobyte
M Megabyte
G Gigabyte

Two-Sided

Select whether the media is one-sided or two-sided. The default is No.

Yes The media is two-sided. Each side is read as a single volume.
No The media is one-sided.

 

Mount Limit

Enter the maximum number of volumes that can be simultaneously mounted for the device class.

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.

Mount Retention Period

Enter the amount of time, in minutes, to retain an idle volume before dismounting it.

Mount Wait Period

Enter the maximum length of time, in minutes, to wait for a volume to be mounted.
