Troubleshooting: Your Storage Array Software

b

Remove the storage array with the unresponsive status from MDSM,

and add that storage array again.
If the storage array returns to optimal status, you have completed

this procedure.

c

Examine the ethernet cables to ensure that you cannot see any

damage and that they are tightly connected.

d

Ensure that the applicable network configuration tasks are done (for

example, the IP addresses are assigned to each controller).

5 Ensure that the controller firmware is compatible with MDSM on your

management station. If the controller firmware was upgraded, the MDSM

may not have access to the storage array. A new version of MDSM may be

needed to manage the storage array with the new version of the controller

firmware.
If this problem exists, see

dell.com/support.

6 Look to see if there is too much network traffic to one or more controllers.

This problem corrects itself because the MDSM tries to re-establish

communication with the controllers in the storage array at regular times. If

the storage array was unresponsive and a subsequent try 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 are made, the controller

stops responding. This problem corrects itself because after some

TCP/IP connections complete, the controller then becomes responsive

to other connection tries.

8 If the storage array is still unresponsive, problems may exist with

the controllers.

If these problems exist, see dell.com/support.
