Dell POWERVAULT MD3600I - Manual (Page 235)

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 have
been assigned to each controller).
5. Make sure that the controller firmware is compatible with MD Storage Manager on your management station. If the
controller firmware was upgraded, the MD Storage Manager may not have access to the storage array. A new
version of MD Storage Manager may be needed to manage the storage array with the new version of the controller
firmware.
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 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 .
