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.
Select the recording format to be used when writing data to media.
Drive | Specifies that ADSM selects the highest format that can be supported by the drive on which a volume is mounted. |
650MB | Specifies that ADSM writes data to a 650 MB 5.25-inch optical drive. |
1300MB | Specifies that ADSM writes data to a 1300 MB 5.25-inch optical drive. |
2600MB | Specifies that ADSM writes data to a 2600 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. This value can be any number from 0 to 256.
Possible values for this parameter:
Drives | Specifies that ADSM determines the mount limit based on the number of drives defined and online in the library. The default is Drives. For external libraries you should not use the value of Drives. You need to specify the number of drives for the library as the Mountlimit value. |
mount limitvalue | Specify a number for the maximum number of drives used concurrently in this device class by ADSM. This value must never be allowed to exceed the number of drives that are defined and online in the library that services this device class. |
0 | The value of zero prevents new transactions from gaining access to the storage pool. |
Enter a number, to be interpreted as minutes, for the amount of time 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 a scale factor..
Scale factors and their meanings are:
K | Kilobyte |
M | Megabyte |
G | Gigabyte |
Enter the maximum length of time, in minutes, to wait for a volume to be mounted in a manual library.
