Defining a File Device Class

To define a device class, first complete the following fields and then click Finish, or click Cancel to end the task.

Device Class Name

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 files that can be simultaneously opened for input/output.

If the device class is to be shared with a storage agent (Shared parameter equals Yes), a drive will be defined up to the Mount Limit value (This does not apply to the PASE server).

Maximum Capacity

Enter the maximum capacity for the volumes assigned to this device class. The default is 4M.

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

K Kilobyte
M Megabyte
G Gigabyte

Directory

Enter the directory location of the file or files used in this device class. This parameter is optional. The default is the current working directory of the server at the time the command is issued.

By entering a directory name, you identify the location where the server places the files that represent storage volumes for this device class.

Shared

Note: This field does not apply to PASE servers.

Specifies that this FILE devclass will be shared between the server and one or more storage agents. To prepare for sharing, a library will be automatically defined along with a number of drives corresponding to the Mount Limit.
