Changing Device Information for Optical Stand-Alone Devices

To change device information for an existing tape stand-alone device, take the following steps:

1. Type WRKDEVBRM at a command line and press Enter.
2. At the Work with Devices display, locate the name of the device you want to work with and type a 2 (Change) in the Opt column. This takes you to the Change Optical Device display.

3. Change the parameters as needed. Following are brief summaries of the key parameters on this display:
   • In the Allow densities field you can indicate the density at which your device can read and write to media. BRMS separates densities into the read and write densities that are allowed by your device. This separation recognizes that some devices can read media to a device but cannot write to it and vice versa. Other devices can read and write the same densities. The ability to specify the densities that a device can read or write is particularly useful when using device pooling.
   • In the Transfer Rate per Second field you can indicate the rate which the media device transfers data to and from storage media. The possible values are *DEVTYPE which is the default transfer rate of the selected device, or rate you specify in megabytes/gigabytes per second.
4. After you have changed and reviewed these and other parameters as needed, press Enter to return to the Work with Devices display.
