Use the iLO Dedicated Network Port or Shared Network PortNetwork General Settingspage to configure general network settings. You must have the Configure iLO Settings privilege to make changes on this page.
1. Navigate to theNetwork→iLO Dedicated Network PortorNetwork→Shared Network Port
page.
2. Click theGeneraltab, as shown inFigure 32 (page 76).
3. Enter the following information in theiLO Hostname Settingssection:
• iLO Subsystem Name (Host Name)—The DNS name of the iLO subsystem (for example,
iloinstead ofilo.example.com). This name can be used only if DHCP and DNS are configured to connect to the iLO subsystem name instead of the IP address.
iLO subsystem-name limitations follow:
◦
Name service limitations—The subsystem name is used as part of the DNS name. DNS allows alphanumeric characters and hyphens.–
– Name service limitations also apply to theDomain Name.
◦
Namespace issues—To avoid these issues:– Do not use the underscore character.
– Limit subsystem names to 15 characters.
– Verify that you can ping iLO by IP address and by DNS/WINS name.
– Verify that NSLOOKUP resolves the iLO network address correctly and that no namespace conflicts exist.
– If you are using both DNS and WINS, verify that they resolve the iLO network address correctly.
– Flush the DNS name if you make any namespace changes.
• Domain Name—The iLO domain name. If DHCP is not used, enter a domain name. 4. Enter the following information in theNIC Settingssection:
• Select theUse iLO Dedicated Network Port,Use Shared Network Port – LOM, orUse Shared Network Port – Flexible LOMcheck box to enable or disable the iLO Dedicated Network Port or Shared Network Port.
◦
iLO Dedicated Network Port—Uses a NIC with a jack on the back of the server. The NIC handles iLO traffic only.◦
Shared Network Port – LOM—Uses a NIC that is built into the server. The NIC handles server network traffic and can, if iLO is configured to do so, handle iLO traffic at the same time.◦
Shared Network Port – Flexible LOM—Uses an optional NIC that plugs into a special slot on the server. The NIC handles server network traffic and can, if iLO is configured to do so, handle iLO traffic at the same time. Not all servers support a FlexibleLOM. For the list of servers that support the Shared Network Port – FlexibleLOM option, see“FlexibleLOM support” (page 271).On systems that have more than one Shared Network Port option, select the check box, and then select the LOM or FlexibleLOM option.
For more information about using the Shared Network Port, see“Using the iLO Shared Network Port” (page 78).
• Select aLink State(iLO Dedicated Network Port only).
The link setting controls the speed and duplex settings of the iLO network transceiver. NOTE: This setting is not available on blade servers.
The available settings follow:
◦
Automatic(default)—Enables iLO to negotiate the highest supported link speed and duplex settings when connected to the network◦
1000BaseT, Full-duplex—Forces a 1 Gb connection that uses full duplex (not supported for BL c-Class servers)◦
1000BaseT, Half-duplex—Forces a 1 Gb connection that uses half duplex (not supported for BL c-Class servers)◦
100BaseT, Full-duplex—Forces a 100 Mb connection using full duplex◦
100BaseT, Half-duplex—Forces a 100 Mb connection using half duplex◦
10BaseT, Full-duplex—Forces a 10 Mb connection using full duplex◦
10BaseT, Half-duplex—Forces a 10 Mb connection using half duplexIf the Shared Network Port is enabled, you cannot modify the link state or duplex option. In Shared Network Port configurations, link settings must be managed in the operating system.
• Select or clear theEnable VLANcheck box to enable or disable VLAN (Shared Network Port only).
When the Shared Network Port is active and VLAN is enabled, the iLO Shared Network Port becomes part of a VLAN. All network devices with different VLAN tags will appear to be on separate LANs, even if they are physically connected to the same LAN.
• If you enabled VLAN, enter aVLAN Tag(Shared Network Port only). All network devices that you want to communicate with each other must have the same VLAN tag. The VLAN tag can be any number between 1 and 4094.
5. ClickSubmitto save the changes.
6. If you are finished configuring the iLO network settings on theGeneral,IPv4,IPv6, andSNTP
tabs, clickResetto restart iLO.
It might take several minutes before you can re-establish a connection.
Using the iLO Shared Network Port
The iLO Shared Network Port feature enables you to choose between the Shared Network Port LOM, FlexibleLOM, and the iLO Dedicated Network Port for server management. When you enable the iLO Shared Network Port, regular network traffic and iLO network traffic pass through the selected Shared Network Port NIC. The iLO Shared Network Port does not incur an iLO performance penalty. Peak iLO traffic is less than 2 Mb/s on a NIC capable of a speed of 1 GB/s or 10 GB/s. iLO traffic volume is low unless the Virtual Media or Remote Console feature is in use.
On servers that do not have an iLO Dedicated Network Port, the standard hardware configuration provides iLO network connectivity only through the iLO Shared Network Port connection. The iLO firmware automatically defaults to the Shared Network Port.
The iLO Shared Network Port uses the network port labeled NIC 1 on the rear panel of the server whenUse Shared Network Port – LOM is selected, and uses the network port labeled 1 on the FlexibleLOM adapter ifUse Shared Network Port – Flexible LOMis selected. NIC numbering in the operating system can be different from system numbering.
When using the iLO Shared Network Port, observe the following:
• The iLO Shared Network Port is supported on all nonblade servers.
• For the list of servers that support the iLO Shared Network Port FlexibleLOM feature, see “FlexibleLOM support” (page 271).
• You can use the iLO Shared Network Port and the iLO Dedicated Network Port only for iLO server management.
• The iLO Shared Network Port is not an availability feature. Its purpose is to allow managed network port consolidation.
• Due to server auxiliary-power budget limitations, some 1Gb/s copper network adapters used for iLO Shared Network Port functionality might only run at 10/100 speed when the server is powered off. To avoid this issue, HP recommends configuring the switch the iLO Shared Network Port is connected to for autonegotiation.
If you want to configure the iLO switch for a speed of 1Gb/s, be aware that some copper iLO Shared Network Port adapters might lose connectivity when the server is powered off. Connectivity will return when the server is powered back on.
• The iLO Shared Network Port and iLO Dedicated Network Port cannot operate simultaneously. If you enable the iLO Dedicated Network Port, you will disable the iLO Shared Network Port. If you enable the iLO Shared Network Port, you will disable the iLO Dedicated Network Port.
• Disabling the iLO Shared Network Port does not completely disable the system NIC—network traffic still passes through the NIC. When the iLO Shared Network Port is disabled, any traffic going to or originating from iLO will not pass through the iLO Shared Network Port because that port is no longer shared with iLO.
• Using the iLO Shared Network Port can create a single failure point. If the port fails or is unplugged, both the host and iLO become unavailable to the network.
Enabling the iLO Shared Network Port feature
The iLO Shared Network Port feature is disabled by default on servers that are shipped with a Dedicated iLO Management NIC. You can enable it by using the following methods:
• iLO RBSU—For more information, see “Enabling the iLO Shared Network Port feature through iLO RBSU” (page 79).
• iLO web interface—For more information, see “Enabling the iLO Shared Network Port feature through the iLO web interface” (page 80).
• XML configuration and control scripts—For more information, see the HP iLO 4 Scripting and Command Line Guide.
• SMASH CLP—For more information, see the HP iLO 4 Scripting and Command Line Guide.
