Powering Off the Controller
Some replacement tasks require you to power off the controller. Note that there will be a loss of access to the storage unless the system is in a clustered configuration. The recommended methods for powering off a controller depend on whether you have completed initial configuration. Use a power off method from one of the following two situations.
If you have completed initial configuration, power off the controller using one of the following methods:
-
Log in to the BUI and click the power icon
on the left side under the masthead. -
SSH in to the appliance and enter the maintenance system poweroff command.
-
Use a pen or non-conducting pointed object to press and release the Power button on the front panel.
If you have not completed the initial configuration steps, power off the controller using one of the following methods:
-
Use a pen or non-conducting pointed object to press and release the Power button on the front panel.
-
SSH or use a serial connection to log in to the service processor (SP), and then issue the command stop /SYS.
-
To initiate an emergency shutdown during which all applications and files will be closed abruptly without saving, press and hold the Power button for at least four seconds until the Power/OK status indicator on the front panel flashes, indicating that the storage controller is in standby power mode. To completely remove power, disconnect the AC power cords from the rear panel of the storage controller.
