Placing a compute node into maintenance mode

Before a Sun Server X3-2 compute node can be powered down, it must be placed into maintenance mode from within Oracle VM Manager. As a result, all virtual machines running on the compute node are automatically migrated to other servers in the Oracle VM server pool, if they are available. For details, refer to the section “Placing an Oracle VM Server into Maintenance Mode” in the Oracle VM User's Guide.

1. Log in to the Oracle VM Manager Web UI.

   For details, refer to the section “Section 3.2, “Logging in to the Oracle VM Manager Web UI”” in the Oracle Virtual Compute Appliance Administrator's Guide.

   1. Enter the following address in a Web browser: https://manager-vip:7002/ovm/console.

      Replace manager-vip with the virtual IP address, or corresponding host name, that you have configured for your management nodes during installation.

   2. Enter the Oracle VM Manager user name and password in the respective fields and click OK.

2. In the Servers and VMs tab, select the Oracle VM Server in the navigation pane. Click Edit Server in the management pane toolbar.

   The Edit Server dialog box is displayed.

3. Select the Maintenance Mode check box to place the Oracle VM Server into maintenance mode. Click OK.

   The Oracle VM Server is in maintenance mode and ready for servicing.

4. When the Sun Server X3-2 is ready to rejoin the Oracle VM server pool, perform the same procedure and clear the Maintenance Mode check box.

Powering down the system

These steps briefly describe the procedure. For detailed instructions, refer to the chapter “Preparing for Service” in the Sun Server X3-2 Service Manual (part no. E22313).

1. Power down the server gracefully whenever possible.

   The easiest way is to press and quickly release the Power button on the front panel.

2. Perform immediate shutdown only if the system does not respond to graceful power-down tasks.

   Caution

   System data may become corrupted during an immediate power down. Use this task only after attempting to power down the server gracefully.

3. Extend the server to the maintenance position.

4. Disconnect the power cables and data cables from the server.

5. Most service operations can be performed while the server is in the maintenance position.

   However, if necessary, remove the cable management arm (CMA) and pull the server out of the rack.

   Caution

   The server weighs approximately 18.1 kg (39.9 lb). Two people are required to dismount and carry the chassis.

Returning the system to operation

These steps briefly describe the procedure. For detailed instructions, refer to the chapter “Returning the Server to Operation” in the Sun Server X3-2 Service Manual (part no. E22313).

1. If the top cover was removed to service a component, reinstall the top cover on the server.

2. If the server was removed, reinstall it into the rack.

3. Reconnect data cables and power cords.

4. Return the server to its normal operational position in the rack, making sure the CMA is correctly installed.

5. Power on the server.
