If you want to use the Sun StorEdge A5x00 module, you must install either the SUNWluxop storage patch, or the SUNWluxox storage patch, or both storage patches for the corresponding operating environment. If you load the A5x00 module and did not install the appropriate patch, the Sun Management Center agent cannot run. You can obtain either patch at http://www.sun.com.
Install the patches on the server to which the A5x00 storage device is attached.
