Configuring The Compute Node - Lenovo Flex System x220 Installation And Service Manual

5. Locate the boot backup UEFI switch on the switch block and change the switch to the On position (see
"System-board switches" on page 18).
6. Replace the cover and reinstall the compute node in the Flex System chassis (see "Installing the
compute node cover" on page 644 and "Installing a compute node in a chassis" on page 639).
7. Update the UEFI code (see "Updating firmware and device drivers" on page 21).
8. Turn off the compute node and remove it from the Flex System chassis (see "Turning off the compute
node" on page 16 and "Removing a compute node from a chassis" on page 639).
9. Remove the cover of the compute node (see "Removing the compute node cover" on page 643).
10. Locate the boot backup UEFI switch on the switch block and change the switch to the Off position (see
"System-board switches" on page 18).
11. Replace the cover and reinstall the compute node in the Flex System chassis (see "Installing the
compute node cover" on page 644 and "Installing a compute node in a chassis" on page 639).
12. Restart the compute node (see "Turning on the compute node" on page 15).
Important: If you are unable to manually restore the UEFI code after several attempts, replace the
system-board assembly (see "Removing the system-board assembly" on page 683 and "Installing the
system-board assembly" on page 684).

Configuring the compute node

Use this information to configure the compute node.
To perform a typical initial configuration, complete the following steps.
Note: To configure a compute node, you configure the IP address of the IMM through the CMM web
interface. For more information, see the "Flex System Chassis Management Module: User's Guide" at
http://pic.dhe.ibm.com/infocenter/flexsys/information/topic/com.lenovo.acc.cmm.doc/cmm_ui_config_
chassis_components.html.
Step 1. Configure the Unified Extensible Firmware Interface (UEFI) firmware for the compute node by using
the Setup utility (see "Using the Setup utility" on page 24 or the Advanced Setup Utility (ASU) (see
https://support.lenovo.com/us/en/ documents/LNVO-ASU).
For more information about firmware configuration options, see http://www.ibm.com/support/entry/
portal/docdisplay?lndocid=MIGR-5083207.
Step 2. Set the boot protocol by using the Setup utility (see "Setting the boot protocol to boot from legacy
devices using the Setup utility" on page 29).
You can temporarily redefine the boot order by using the Boot Selection menu program (see "Using
the Boot Selection Menu program" on page 30).
Step 3. Configure the RAID array.
You can install up to two hard disk drives in the compute node and implement RAID level-0
(striping) or RAID level-1 (mirroring) arrays in operating systems that are listed on the ServerProven
list at http://www.lenovo.com/ serverproven/. For more about configuring the ServeRAID controller,
see "Configuring a RAID array" on page 33.
If an optional RAID expansion adapter is installed, you can use it to control all the hard disk drives
that are installed in the compute node. See the documentation that comes with the expansion
adapter for information about how to configure the RAID array.
Important: You must create the RAID array before you install the operating system on the compute
node.
