This section describes how to change the settings for the Virtual NIC mode. After changing the settings, you need to reflect the changes in the operations following some procedures. Note that the change distribution procedures vary depending on the command used for changing the settings, and whether the settings were changed in a single system configuration (no cluster is used), or in a cluster configuration.

Changing Procedure
The following shows the procedure for changing configuration information. Changes become effective by performing distribution procedures.
Inactivate the target virtual interface using the "stphanet" command. For information, see "7.3 stphanet Command".
Change the configuration information.
After changing the configuration information, activate the target virtual interface using the "strhanet" command. For information, see "7.2 strhanet Command".
The following shows the procedure for changing information of network monitoring. Changes become effective by performing distribution procedures.
Stop network monitoring with the hanetpathmon off command.
Change the monitoring target with the hanetpathmon target command.
Change the following monitoring parameters with the hanetpathmon param command:
Automatic start of monitoring
Monitoring period
The number of monitoring
The number of recovery monitoring
Link up waiting period
Automatic fail-back
Cluster switching
Start network monitoring with the hanetpathmon on command.
For details, see "7.12 hanetpathmon Command".
The following shows the procedure for changing link status monitoring parameters. Changes become effective by performing distribution procedures.
Change the following link status monitoring parameters with the hanetparam command:
Link down detection timer

For details, see "7.6 hanetparam Command".
The following lists the information that can be changed for Virtual NIC mode. No information can be changed besides the information listed below. Delete the target definition and add it again.
Configuration definition information
For RHEL8, you can change the information such as IP addresses and a subnet mask by editing the network setting file (/etc/sysconfig/network-scripts/ifcfg-shaX) of the virtual interface. For RHEL9, you can configure the same settings with the nmcli command. For details, see "3.3.3 Virtual NIC mode".
Network monitoring information
The following information can be changed with the hanetpathmon command. For details, see "7.12 hanetpathmon Command".
Monitored IP (primary monitored remote system IP address and secondary monitored remote system IP address)
Monitored IP VLAN (primary monitored remote system IP address and secondary monitored remote system IP address)
Automatic start of monitoring
Monitoring period
The number of monitoring
The number of recovery monitoring
Link up waiting period
Automatic fail-back
Cluster switching (failover)
Information of link status monitoring parameter
The following information can be changed with the hanetparam command. For details, see "7.6 hanetparam Command".
Link down detection timer
Link up detection timer
Link status monitoring standby timer
Note
If a virtual bridge is connected to a virtual interface of the Virtual NIC mode, the virtual interface cannot be deactivated. Deactivate it after disconnecting the virtual interface from the virtual bridge.
