Configure networks for servers

From the network configuration screen, you can change server-wide parameters like the system name as well as the settings for each individual NIC on the server. If multiple servers are selected, bulk host name and IP assignments can be performed.

To change the network configuration of a server

  1. From the Servers screen, select one or more servers from the master pane. In order to change the network configuration for multiple servers, the servers must meet the following requirements:

    • The servers must be in a managed state.

    • The servers must be the same hardware model.

    • The servers must have the same number of NICs.

    • The servers’ NIC names must all be the same. For example, if you have two servers with two NICs each and the first server has NIC names eth0 and eth1, the second server’s NICs must also be named eth0 and eth1.

    • Each NIC must have a name.

    • The servers’ Deployment interface names must be the same.


    [NOTE: ]

    NOTE: If you select too many servers, a message is displayed “Unable to load server NIC information. The network configuration server limit has been exceeded”. Select fewer servers so the total is under the limit.


  2. Select ActionsConfigure network.

  3. From the Configure network screen, make your changes in the following screen sections:

    • Server Configuration – edit general networking and DNS information

    • NIC Configuration – allows you to select either DHCP or static IP for each NIC


    [IMPORTANT: ]

    IMPORTANT: Because operating systems might behave differently to network personalization, HP recommends testing your personalization scheme on a single server before applying it to a large number of servers.



    [NOTE: ]

    NOTE: Clearing a field will not remove the existing server information.


Server network configuration screen details

Screen component Description
Server Configuration
Host name

Description:

This area is displayed for a single server selection and allows you to change the unqualified host name of the server from the display name assigned when the server is first discovered to a name that has more meaning in your facility.

Data type:

Alphanumeric. Hyphens (-) and periods (.) are allowed. No spaces or special characters.

Default value:

None

Required:

No

Examples:

servername

Host name prefix

This field is only displayed for multiple server selection and is used with the Starting index to generate host names automatically.

This area allows you to change the unqualified host name of the server from the name assigned when the server is first discovered to a name that has more meaning in your facility.

The servers selected will be given a host name beginning with this prefix and ending with a number starting with the Starting index and incrementing for each server.


[NOTE: ]

NOTE: Host names are assigned top to bottom as displayed in the Run OS Build Plan Servers table. Changing the table order affects host name and IP address assignments.


Starting index

This field is only displayed for multiple server selection and is used with the Host name prefix to generate host names automatically.

This area allows you to change the unqualified host name of the server from the name assigned when the server is first discovered to a name that has more meaning in your facility.

The servers selected will be given a host name beginning with the Host name prefix and continuing with a number starting with this index and incrementing for each server.

You may add leading zeros to this field to increase the number of digits used for numbering.

Network Configuration
NIC check boxes

Description:

Select the NICs you would like to modify. (If you do not configure a NIC on this screen, its configuration will not be changed on the target server.) Then select your IP assignment:

  • DHCP – Make a DHCP request to get the IP address and other networking information from a DHCP server. Choosing this might mean the system will get a different IP address each time it boots.

  • Static – Specify an IP address and network mask that will stay the same on every boot. If you select this option, you are required to specify an IP address and network mask. These fields will be displayed automatically if this option is selected.

    • IP addresses are numeric characters separated by periods (.) such as

      192.168.1.1

      This address is displayed for a single server selection.

    • Starting IP address: Servers will be assigned incremented static IP addresses beginning with this address. This is displayed for multiple server selection.

    • A Network mask is the IPv4 mask representing the bits reserved for network identification such as:

      255.255.255.0

      This address is displayed for a single server selection.

Default value:

DHCP

View button

A View Generated Settings table will be displayed to show how the values will resolve for each host if this server configuration is saved.

  • Display Name – The name displayed in the Servers master pane.

  • Host Name – The server name you can set with the Host name text box in the Server Configuration area of the Configure network screen.

  • NIC – The name of the NIC as set within the server.

  • MAC Address – The hardware address for the NIC.

  • IP Address – The assigned static IP address or DHCP if the IP address will be assigned by DHCP, depending on the selection for this NIC.

Network Configuration screen buttons
OK

Saves the network configuration information for the server using the parameters on the screen.
