7.8 Network Redundancy and VLAN Settings of L-Servers

In Resource Orchestrator, when images of Red Hat Enterprise Linux are specified, IP address settings of public LANs are not configured. Server NIC redundancy and the OS settings of tagged VLANs are also not configured.
When starting an OS after L-Server creation, set the image to be configured automatically after creating an L-Server. For this setting, use the image collected in the state where the scripts to configure the network settings have been prepared beforehand.
In this case, prepare a script like the following, and perform collection of a cloning image with the script executed once on starting of the OS.

According to the description in the network information file, perform the following settings for using NIC redundancy software (such as Windows Intel PROSet/Linux bonding).

NIC Redundancy
Tagged VLAN Configuration
IP Address Configuration

For details on the specifications of the network information file, refer to "Network Information File".

Network Information File

The settings for NIC redundancy and tagged VLANs for a physical L-Server are described in the file. It is automatically transferred to a physical L-Server during creation. When the rcxadm lserver command is executed after creation of the physical L-Server, the network information file will be transferred to the L-Server.

Information

Network Information Extension Files

When using a driver specific parameter such as GLS or Bonding for the script configuring the network, describe the information in the following files:

Network unit parameter (describes IP addresses and static routing of monitoring targets for GLS or Bonding)
[Windows]
Installation_folder\SVROR\Manager\etc\customize_data\net\net_info.network resource name.conf
[Linux]
/etc/opt/FJSVrcvmr/customize_data/net/net_info.network_resource_name.conf
L-Server unit parameter (configures QoS or others to set for NICs)
[Windows]
Installation_folder\SVROR\Manager\etc\customize_data\net\net_info.l_server name.conf
[Linux]
/etc/opt/FJSVrcvmr/customize_data/net/net_info.l_server name.conf

Character Code: UTF-8

Line Break Code

[Windows]
CR/LF

[Linux]
LF

When deploying L-Servers, send a network information file with content matching the L-Server name or the name of a network resource connected to the L-Server, to the destination server.

The sample script for configuring a network is stored on the Resource Orchestrator DVD-ROM (disk 1).

Storage Location for Tool

[Windows]
\DISK1\Common\network_script
