Powering Off the Compute Node

The G5500 configured with half-width compute nodes allows one compute node to power off. The power-off of the node does not affect operation of the other compute node.

Before powering off the compute node, ensure that server data has been saved and drive services have been stopped.

Do not forcibly power it off when read and write operations are being performed on drives. Otherwise, bad sectors may occur, compromising data sources.

Power off the compute node using one of the following methods:

• Use cables to connect the server to a video display, keyboard, and mouse, and shut down the server OS to power off the server.
• Hold down the power button on the front panel until the compute node is powered off. For details about the power button position, see Front Panel Indicators and Buttons.

  After the compute node is powered off forcibly, wait for more than 10s to ensure that it is powered off completely. Then you can power it on again.

• Press and hold down the power button on the front panel until the server is powered off. For details about the power button position, see Front Panel Indicators and Buttons.
• Force the compute node to enter the standby state (the power indicator is steady yellow).
  • Log in to the Remote Virtual Console of the compute node, and shut down the OS.

    For details about how to log in to the Remote Virtual Console, see Logging In to the Remote Virtual Console.

  • Power off the compute node using the iBMC WebUI.
    1. Log in to the iBMC WebUI. For details, see Logging In to the iBMC WebUI.
    2. Choose Power > Power Control.

       The Power Control page is displayed, as shown in Figure 3-2.

    3. Click Power Off. In the displayed dialog box, click Yes to power off the compute node.
  • Power off the compute node through the iBMC CLI.
    1. Log in to the iBMC CLI. For details, see Logging In to the iBMC CLI.
    2. On the iBMC CLI, run the ipmcset -d powerstate -v 0 command to power off the server or the ipmcset -d powerstate -v 2 to forcibly power it off.

       A forced power-off may cause data loss or program damage. Forcibly power off the server only when necessary.

    3. Enter y or Y to power off the server.
