6. Look to see if there is too much network traffic to one or more controllers. This problem corrects itself because the MD 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, the storage array becomes responsive.

7. For an out-of-band storage array, look to see if management operations are taking place on the storage array from other storage

management stations. The type of management operations being done and the number of management 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 problem corrects itself because after some TCP/IP connections are complete, the

controller becomes responsive to other connection 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

software

The Host Context Agent software module is the software component that resides on the server or management station that

communicates with the MD Series storage arrays. The SMagent software automatically starts after you reboot the host.

Starting SMagent software in Linux

To start or restart the Host Context Agent software in Linux, enter the following command at the prompt:
