Non-Emergency Power Procedure - Oracle Exalogic Elastic Cloud Owner's Manual

• Cautions and Warnings

1.4.1 Non-emergency Power Procedure

Compute nodes and controllers in the storage device are powered on by either
pressing the power button on the front of the machine, or by logging in to the ILOM
interface and applying power to the system.
Compute nodes and controllers can also be powered off by using operating system
commands.
For example, you can use the following command on the Oracle Linux operating
system:
shutdown -h -y now
On the Oracle Solaris operating system, you can use the following command:
shutdown -i 5 now
1.4.1.1 Power On Sequence
The power on sequence is as follows:
Rack, including switches.
1.
Ensure that the switches have had power applied for a few minutes to complete
power-on configuration before starting the storage controllers and compute nodes.
Storage server heads attached to the chassis of the storage device.
2.
Wait for a few minutes for the storage appliance to boot and start NFS services and
daemons.
Compute nodes.
3.
1.4.1.2 Power Off Sequence
The power off sequence is as follows:
Compute nodes
1.
Note:
You can use this command after logging in to the compute nodes.
The network switches do not have power switches. They power off when
power is removed, by way of the PDU or at the breaker in the data center.
Note:
After power is applied, the LEDs on all compute nodes and storage server
heads will start blinking after a few minutes. From the rear of the rack, you
can see the green LEDs on the PSUs turn on instantly after power is applied.
In addition, from the rear of the rack, you can see the display on the PDUs that
lights up once power is available.
