The following section provides a detailed procedure for configuring a Cisco UCS C-Series standalone rack server for use in the FlexPod Express configuration.

Perform initial Cisco UCS C-Series standalone server setup for Cisco Integrated Management Server

Complete these steps for the initial setup of the CIMC interface for Cisco UCS C-Series standalone servers.

The following table lists the information needed to configure CIMC for each Cisco UCS C-Series standalone server.

Detail Detail value

CIMC IP address

<<cimc_ip>>

CIMC subnet mask

<<cimc_netmask>>

CIMC default gateway

<<cimc_gateway>>

Note The CIMC version used in this validation is CIMC 3.1.3(g).

All servers

  1. Attach the Cisco keyboard, video, and mouse (KVM) dongle (provided with the server) to the KVM port on the front of the server. Plug a VGA monitor and USB keyboard into the appropriate KVM dongle ports.

  2. Power on the server and press F8 when prompted to enter the CIMC configuration.

  6. Reboot the server to boot with your new boot order.

Disable RAID controller (if present)

Complete the following steps if your C-Series server contains a RAID controller. A RAID controller is not needed in the boot from SAN configuration. Optionally, you can also physically remove the RAID controller from the server.

  1. Click BIOS on the left navigation pane in CIMC.

  2. Select Configure BIOS.

  3. Scroll down to PCIe Slot:HBA Option ROM.

  4. If the value is not already disabled, set it to disabled.

Configure Cisco VIC1387 for iSCSI boot

The following configuration steps are for the Cisco VIC 1387 for iSCSI boot.

Create iSCSI vNICs

  1. Click Add to create a vNIC.

  2. In the Add vNIC section, enter the following settings:

    • Name: iSCSI-vNIC-A

    • MTU: 9000

    • Default VLAN: <<var_iscsi_vlan_a>>

    • VLAN Mode: TRUNK

    • Enable PXE boot: Check
