Verifying the Installation
It is a good idea to run the RAID Manager for DOS (DRM) Array Monitor after you
first install the subsystem or start DRM because it checks all controllers, drives and
other components for any problems in your array subsystem as well as verifies the
communication paths between the controllers and the DRM PC. See "Using the
Array Monitor" on page 223 for more information on the Array Monitor.
Use the following procedure to determine if there are any subsystem components
that are not working properly:
1. From the DRM main menu, select Status

and altering cache parameters that should only be used under the direction of your
next level of support.
