If both controllers are operational and one needs servicing, do the following to disable and then service the controller: Note: The MSA operates in a non-redundant mode during this procedure. a. Access a supported management utility for the MSA. b. In the utility, disable the controller to be removed. For details, see the utility online help or MSA user documentation. c. Wait for array controller disabled to display on the controller LCD panel. d. Remove the disabled controller for servicing or replacement. Caution: If an operational controller is removed without first being disabled, the active controller might halt. To clear this fault condition, you must power-cycle the MSA.
