c) Examine the Ethernet cables to make sure that you cannot see any damage and that they are tightly connected.d) Make sure that the applicable network configuration tasks have been done (for example, the IP addresses havebeen assigned to each controller).5. Make sure that the controller firmware is compatible with MD Storage Manager on your management station. If thecontroller firmware was upgraded, the MD Storage Manager may not have access to the storage array. A newversion of MD Storage Manager may be needed to manage the storage array with the new version of the controllerfirmware.If this problem exists, see Getting Help.6. Look to see if there is too much network traffic to one or more controllers. This problem corrects itself because theMD Storage Manager tries to re-establish communication with the controllers in the storage array at regular times.If the storage array was unresponsive and a subsequent attempt to connect to the storage array succeeds, thestorage array becomes responsive.7. For an out-of-band storage array, look to see if management operations are taking place on the storage array fromother storage management stations. The type of management operations being done and the number ofmanagement sessions taking place together establish the number of TCP/IP connections made to a controller.When the maximum number of TCP/IP connections have been made, the controller stops responding. This problemcorrects itself because after some TCP/IP connections are complete, the controller becomes responsive to otherconnection tries.8. If the storage array is still unresponsive, problems may exist with the controllers.If these problems persist, see Getting Help.Starting Or Restarting The Host Context Agent SoftwareThe Host Context Agent software module is the software component that resides on the server or management stationthat communicates with the MD Series Dense storage arrays. The SMagent software automatically starts after youreboot the host.Starting The SMagent Software In Windows1. Do one of the following:– Click Start → Settings → Control Panel → Administrative Tools → Services– Click Start → Administrative Tools → Services2. In the Services dialog, select Modular Disk Storage Manager Agent.3. If the modular disk storage manager agent is running, click Action → Stop and then wait approximately 5 seconds.4. Click Action → Start.Starting The SMagent Software In LinuxTo start or restart the Host Context Agent software in Linux, enter the following command at the prompt:SMagent startThe SMagent software may take a little time to initialize. The cursor is shown, but the terminal window does notrespond. When the program starts, the following message is displayed:SMagent started.After the program completes the startup process, text similar to the following, is displayed:Modular Disk Storage Manager Agent, Version 90.02.A6.14173
