Defining a File Device Class

To define a file device class, 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. The maximum length of the device class name is 30 characters.

Mount Limit

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

Maximum Capacity

Enter the maximum capacity for the file volumes. The largest accepted value is 2047MB and the smallest accepted value is 100KB. The default is 1MB.

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

File Mode or Directory

File Mode
Enter a 1 or 2 character string. The first character is required and must be a letter from A to Z. The second character is optional and can be a numeric digit from 0 to 6. The first character identifies the minidisk that has been accessed in read-write mode.
Directory
Enter a fully qualified SFS directory name of the format filepool:userid followed by up to 8 sub-directory names which are separated by periods. Tivoli Storage Manager servers should not share SFS directories; each server must have separate directories for file device classes. The server must have write authority to the directory and files unless all volumes are read-only or full.
