Question

List and describe the steps in the power-on procedure

Answer 1

Perform the following procedure to power on the MiniCluster.

1. If you powered off and disconnected the power cords from a storage array (and storage expansion shelf if one is present), reconnect the power cords now.
2. Power on the storage array (and storage expansion shelf if one is present) by switching the power supply On/Off button on each power supply to the On position.

   The disks begin to initialize and the power supply LEDs light green. This can take several minutes.

   Note - Do not power on the compute nodes until the disks on the storage array and storage expansion shelf have initialized.

3. If you powered off a compute node, reconnect any unplugged power cords now.
4. Power on a compute node on using one of the following methods:

   • Press the recessed Power button on the compute node front panel.

   • Log in to the Oracle ILOM web interface, click Host Management > Power Control, and select Power On from the Select Action list box.

   • Log in to the Oracle ILOM command-line interface (CLI), and type the following command at the Oracle ILOM CLI prompt.

     -> start /SYS

   When the server is powered on and the power-on self-test (POST) code checkpoint tests have completed, the green Power/OK status indicator on the compute node front panel lights and remains lit.

   Note - If you powered off both compute nodes prior to servicing, repeat steps 3 and 4 to power on the second compute node.
