Controller Operations
5.1 HS Array Controller Initialization
The HS array controller is initialized by any one of the following actions:
• A power-up cycle
• A firmware reset
• By pressing the OCP reset (//) button on the front bezel of the HS array
controller
• From a host clear (or bus INIT)
The following action may initialize the controller, but it is not supported:
• When the operator removes and replaces the program card while the
controller is running

Whenever the controller initializes, it steps through a three-phase series of tests
designed to detect any hardware or firmware faults. These are the three tests:
• Built-in self-test
• Core module integrity self-test
• Module integrity self-test DAEMON
Initialization time varies depending on the model of your controller and the size
of your cache module, if any.
Note
Beginning with HSOF Version 2.5, a 60-second delay will occur following
controller restart operations before the CLI becomes active. During this
time, the devices are available to the host, but you will not be able to
enter any CLI commands.

Occasionally, this does not force initialization, so the controller shows no activity. If this
occurs, press the green reset (//) button to initialize the controller.
