Shutting down the system
CAUTION:
To power off the system for more than 96 hours, use HP Command View EVA.
You can use the Shutdown System function to implement the shutdown methods listed below. These
shutdown methods are explained in Table 25 .
• Shutting down the controller (see Shutting the controller down ).
• Restarting the system (see Restarting the System ).
• Uninitializing the system (see Uninitializing the System ).
To ensure that you do not mistakenly activate a shutdown procedure, the default state is always NO,
indicating do not implement this procedure. As a safeguard, implementing any shutdown method
requires you to complete at least two actions.
Table 25 Shutdown methods
LCD prompt Description
Restart System? Implementing this procedure establishes communications between the storage
system and HP Command View EVA. This procedure is used to restore
the controller to an operational state where it can communicate with HP
Command View EVA.
Power off system? Implementing this procedure initiates the sequential removal of controller
power. This ensures no data is lost. The reasons for implementing this
procedure include replacing a drive enclosure.
Uninitialize? Implementing this procedure will cause the loss of all data. For a detailed
discussion of this procedure, see Uninitializing the System .
Shutting the controller down
Use the following procedure to access the Shutdown System display and execute a shutdown procedure.
NOTE:
HP Command View EVA is the preferred method for shutting down the controller. Shut down the
controller from the OCP only if HP Command View EVA cannot communicate with the controller.
Shutting down the controller from the OCP removes power from the controller on which the procedure is
performed only. To restore power, toggle the controller’s power switch.
