The server attempts to read device configuration information from defined files and cannot open any of the files.
The operation is ended.
Examine error messages that may have been displayed prior to this message and correct any problems, if possible. Ensure that the defined device configuration files have been created. If you can start the server, you can create the files by using the BACKUP DEVCONFIG command. If you cannot start the server, you will need to create a device configuration file by editing the file and adding the appropriate DEFINE commands for the device class, drive, and library definitions. The contents and requirements for this file are described in the Administrator’s Guide. Make sure that the server has proper authority to read from the defined device configuration files.
