The Enclosure Bay IP Addressing (EBIPA) screens allow you to configure fixed addresses for Onboard Administrator enclosure bays. The EBIPA feature helps to provision a fixed IP address on bay number, which preserves the IP address for a particular bay even if a module is hot-replaced. The management interface for components plugged into the bays must be set for DHCP and can only
be used if the devices are set to boot from DHCP. If a device is configured for static IP, then it must be manually reconfigured to DHCP to change the EBIPA IP address.
The Onboard Administrator GUI lists the IP address for the server blade iLO bay and interconnect module management bay.
The server blade iLO bays and interconnect module management bays can obtain IP addresses on the management network in the following ways:
• DHCP address— The server blade iLO defaults to DHCP addressing, through the network connector of the active Onboard Administrator. Interconnect modules that have an internal management network connection to the Onboard Administrator may also default to the DHCP address.
• EBIPA— When a server blade or interconnect module is inserted into a bay that has EBIPA enabled, that management port will receive the specific static IP address from the Onboard Administrator if that device is configured for DHCP.
There is an important difference between the network the complex is connected to and the management network that the Onboard Administrator uses. Enclosure Bay IP Addressing is used to assign IP addresses to the iLO processors that are bridged through the Onboard Administrator and must not be confused with port mapping for the server blade NICs or for network routers or switches. EBIPA does not assign IP addresses for any other device on the network, and cannot be used as a DHCP server on the network.
TIP: Link-local addresses:To save IP addresses, link-local addressing can be used. Link-local IP addresses can be assigned to blades, iLOs, and interconnect bays within an enclosure. Link-local addresses are intended only for use within a segment of a network and can be used for network configurations that do not require allocated IP addresses on the network.
As a best practice HP recommends the following rules for assigning iLO IP addresses:
• The Monarch Npar IP address should be assigned using EBIPA/DHCP.
• Do not use iLO interfaces to assign iLO static IP addresses.
• Auxiliary blades should be assigned using link-local addressing to save IP addresses. BL920s Gen8 and Gen9 Auxiliary blades will automatically be assigned link-local addresses and cannot be assigned public addresses.
• All IP addresses, with the exception of address ranges 169.254.x.y and 10.254.x.y (reserved for internal management network), are supported as long they are not duplicated. In addition, all the IP addresses must be within the same subnet defined by netmask and IP address so that all OAs as well as all iLOs fit into that subnet.
For more information on setting up link-local addresses, see the HP Integrity Superdome X and
Superdome 2 Onboard Administrator Command Line Interface User Guide.
The administrator sets an independent range for server blade bays and interconnect module bays using the Onboard Administrator EBIPA setup wizard. The first address in a range is assigned to the first bay and then consecutive bays through the range.
To set up your enclosure without an active network connection using EBIPA:
1. Configure a static IP for each Onboard Administrator using the Insight Display, and note the active OA Service IP address on the Insight Display Enclosure Info screen. Attach the client PC to the enclosure Service Port (enclosure Link Up connector) between the OA bays with a standard Ethernet patch cable. The client PC NIC must be configured for DHCP because it gets an IP address in the range of approximately 1 minute later.
2. Launch a web browser (or alternatively a Telnet or Secure Shell session), and select the Onboard Administrator Service IP address as displayed in the enclosure Insight Display on the Enclosure Info screen.
3. Log into the Onboard Administrator as Administrator, using the administrative password attached to the active Onboard Administrator.
4. While the First Time Setup Wizard is running (alternately, after first time setup you can change the EBIPA settings in the Enclosure Settings list), enable Device Bay EBIPA with a starting fixed IP address and enable Interconnect Bay EBIPA with a different starting IP address. The Onboard Administrator then creates 16 sequential IP addresses for the device bays and eight sequential IP addresses for the interconnect bays. Servers in the device bays will automatically get the Device Bay EBIPA addresses within a minute, but the interconnect switch modules must to be manually restarted by clicking theVirtual Powerbutton on each Onboard Administrator Interconnect Module Information screen.
5. Use the Onboard Administrator Device list to be sure that the server blade iLO addresses have been set according to the EBIPA starting IP address and range.
