1. This will start applying power to the components in the rack, and initiate the boot process for
the Interface Modules and Data Modules.
Power-off
Powering the system off must be done solely from either the XIV GUI or the XCLI. You must
be logged on as Storage Administrator (storageadmin role).
Warning: Do not power off the IBM XIV Storage System using the UPS power button
because this can result in the loss of data and system configuration information.
Using the GUI
From the XIV GUI, follow these steps:
1. Click File in the system main window toolbar and choose the option Shutdown System,
as seen in Figure 3-24.
.
Figure 3-24 System shutdown
2. You have to confirm, first by clicking the OK button, and second by entering your login
password, as shown in Figure 3-25.
.

The shutdown takes less than 5 minutes. When done, all fans and front lights on modules and
all UPS lights are off.
Tip: Using the GUI is the most convenient and best way to power off the system.

2. Using the XCLI
From the command prompt, issue the command:
xcli -c "XIV_01" -u admin -p adminadmin shutdown -y
You receive the response:
Command executed successfully
Where XIV_01 is the system name
Or, if using the XCLI session, see the shutdown procedure in Example 3-1.

The shutdown takes less than 5 minutes. When done, all fans and front lights on modules and
all UPS lights are off.
Emergency Power Off (EPO)
The IBM XIV Storage System Machine Types 2810 and 2812 do not have an emergency
power off (EPO) switch; however, you can connect the IBM XIV Storage System to a room
EPO.
EPO precaution: Powering off the IBM XIV Storage System using a room EPO switch
results in data loss and possible loss of configuration. An IBM service representative is
required to recover an XIV system that was turned off using a room EPO switch. If the IBM
XIV Storage System loses ac power but is not powered off using an EPO circuit, data and
configuration are preserved.
