Turning Off the System

You can shut down the Xserve RAID system using the admin software or the power button on the system’s back panel. Both methods are designed to avoid data loss. Do not pull out the power cords to turn off the system.

Important Before shutting down, be sure you have unmounted the drives from your OS.

Shutting Down From a Remote System Using Software

From the host system or a remote computer, use the RAID Admin application to shut down the system.

Follow these steps to shut down the system.

1Use the RAID Admin shutdown command to shut down.

This command stops data flow over the fibre channel connection.

Note: When you shut down, the system is in standby mode. To turn off all power to the system, you must disconnect the power cords.

Important Before removing or replacing a RAID controller, use the admin software or power button to shut down, and disconnect the power cords.

Shutting Down With the Power Button

You can turn off the system by pressing and holding the power button on the back panel for 5 seconds.

Using Status Lights and Other Indicators

The Xserve RAID system has a number of built-in sensors that detect and report essential information, such as power, temperature, and the condition of several key components. You can monitor the system’s operation using the lights on the unit or using the remote monitoring tools.
