To update this device class, first complete the following fields and then click Finish, or click Cancel to end the task.
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.
The following are possible values:
value | Specify the maximum number of drives used concurrently. This value must never 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 maximum length of time, in minutes, to wait for a volume to be mounted.
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 sequential access media labels. For each sequential access volume assigned to this device class, Tivoli Storage Manager uses this prefix to create the data set name.
Example: AB.CD2.E
Enter the maximum amount of data Tivoli Storage Manager can store in the volumes categorized by this device class. This parameter is optional. Specify an integer followed by a scale factor.
Scale factors and their meanings are:
K | Kilobyte |
M | Megabyte |
G | Gigabyte |
Enter the estimated capacity for the volumes categorized by this device class. Specify an integer followed by a scale factor.
Scale factors and their meanings are:
K | Kilobyte |
M | Megabyte |
G | Gigabyte |
Enter the expiration date that is placed on the tape labels for this device class, which are used for allocation. This parameter is optional. Possible values are:
yyddd | Specifies the expiration date for this device class in YYDDD format. |
yyyyddd | Specifies the expiration date for this device class in YYYYDDD format. |
Enter an integer between 1-9999 that defines the length of time, in days, to retain the tape. This parameter is optional.
Select whether devices in this device class should compress files before sending them to the server.
Yes | Specifies that the data for each tape volume is compressed. |
No | Specifies that the data for each tape volume is not compressed. |
Specify whether RACF, if installed, protects volumes assigned to this device class. If protection is provided, RACF profiles are created for the volumes. This parameter is optional.
Possible values for Protection:
No | Specifies that RACF does not protect cartridge volumes assigned to this device class. |
Yes | Specifies that RACF protects cartridge volumes assigned to this device class. RACF profiles are created for volumes when Tivoli Storage Manager first uses the volumes, but profiles are not deleted when volumes are deleted from Tivoli Storage Manager. Profiles will have to be manually deleted. |
Automatic | Specifies that RACF protects cartridge
volumes assigned to this device class. RACF profiles are
deleted when volumes are deleted from Tivoli Storage Manager. If you specify automatic, volumes deleted from Tivoli Storage Manager will no longer be RACF-protected and the data on these volumes will be accessible by other users. |
Enter an esoteric unit name, up to 8 characters, to specify a group of tape devices that support Cartridge System tape. This parameter is optional.
