Problem with accessing the HP MSA P2000 web interface

In HP MSA P2000 arrays, there is an occasional problem with accessing the controller interface from a web browser. Fortunately, the solution to this problem is quite simple and requires no interruption in access to the matrix. Log in with the ssh client or console cable to one of the array controllers and restart it with the command below:

restart mc [a | b | both]

selecting respectively controller a, b or both (both). Some caution should be exercised as a similar command:

restart sc [a | b | both]

it causes restart of the entire storage contoller, not only the management controller, as in the first case.
