3.3.3 Virtual NIC mode

The following shows the procedure to add configuration information.

Set up a virtual interface using the "hanetconfig create" command. For information, see "7.1 hanetconfig Command".
Edit the interface setting file of the virtual interface to set the IP address or netmask.
The interface setting file of the virtual interface is created when the virtual interface is set by the "hanetconfig create" command.
Setup the monitoring destination information by using the "hanetpathmon target" command. For details, see "7.12 hanetpathmon Command".

Configuration of virtual interface

Edit the setting (/etc/sysconfig/network-scripts/ifcfg-shaX file) for a virtual interface as follows:

Item	Value (Example)	Description
DEVICE	shaX	Specify the device name. Set to "ethX".
IPADDR	192.168.1.1	Specify the IP address.
NETMASK	255.255.255.0	Specify the subnet mask. Set either NETMASK or PREFIX.
PREFIX	24	Specify the subnet mask. Set either NETMASK or PREFIX.
NETWORK	192.168.1.0	Specify the network address. Omit this step if PREFIX is specified.
BROADCAST	192.168.1.255	Specify the broadcast address. Omit this step if PREFIX is specified.
BOOTPROTO	static	Specify the protocol when getting the IP address. Set to "static" or "none".
ONBOOT	yes	Select whether to start the virtual interface on startup of the operating system. Set to "yes". When the virtual interface is registered as cluster resource, it is started regardless of the value during the system startup.
DEVICETYPE	sha	Specify the type of the device. Set to "sha".
HOTPLUG	no	Specify use of hotplug. Set to "no".
GATEWAY	192.168.2.1	Specify the IP address when setting the default gateway.
IPV6INIT	yes	Specify "yes" when assigning the IPv6 address.
IPV6ADDR	fec0:1::1/64	Specify the IPv6 address.
IPV6_DEFAULTGW	fec0:1::2	Specify the IPv6 address when setting the default gateway of IPv6.
BRIDGE	br0	Specify the name of the virtual bridge which is to be connected to the virtual interface.

Example of /etc/sysconfig/network-scripts/ifcfg-sha0

When creating a tagged VLAN interface (shaX.Y) of which VLAN-ID is Y on a virtual interface (shaX), edit the setting file (/etc/sysconfig/network-scripts/ifcfg-shaX.Y) for a tagged VLAN interface as follows. The effective range of VLAN-ID which can be specified is from 1 to 4094.

/etc/sysconfig/network-scripts/ifcfg-eth0.2

Note

In Virtual NIC mode, you cannot share physical interfaces with other virtual interfaces.
Just as for the standard interface of the operating system, define IP address and netmask settings in the interface setting file (/etc/sysconfig/network-scripts/ifcfg-shaX) in Virtual NIC mode. Subnet mask settings by the hanetmask command are only necessary when the cluster takeover IP address is set by the hanethvrsc command.
For implementing tagged VLAN communication in Virtual NIC mode, generate a tagged VLAN interface on the virtual interface. The procedure for generation is the same as for the standard tagged VLAN interface of the operating system.
Do not delete a file or change a file name for the interface setting file of the virtual interface (/etc/sysconfig/network-scripts/ifcfg-shaX). If you change or delete a file name, the interface setting file is omitted from the backup target when you back up configuration files by the "hanetbackup" command.
Directly edit the interface setting file (/etc/sysconfig/network-scripts/ifcfg-shaX) for a virtual interface and the setting file (/etc/sysconfig/network-scripts/ifcfg-shaX.Y) for a tagged VLAN interface by using an editor such as vi. You cannot make any settings by using the network configuration function provided by GUI or other interfaces of the operating system.
