Enabling the link monitoring function in NIC switching mode allows NICs to be changed without waiting for a time out from the HUB monitoring (HUB to HUB monitoring) when a NIC link is down.
Moreover, to detect an error by the transfer path monitoring and switch NICs, check the link status of the target beforehand. If the target is in the link down state and the state continues for 5 seconds or longer (when the standby patrol is set: 2.5 seconds or longer), restrict switching NICs.
This function is enabled by the -l option of the hanetpoll command.
[Changes]
Before modification
Even when the transmission route fails when a NIC link is down, the NIC is not changed until the failure is detected by the HUB monitoring (HUB to HUB monitoring).
If an error is detected by the transfer path monitoring, switching is performed regardless of whether the link status of the target NIC.
After modification
When the transmission route fails when a NIC link is down, the NIC is changed without waiting for the failure detection by the HUB monitoring (HUB to HUB monitoring).
When an error is detected by the transfer path monitoring, restrict switching if the target NIC is in the link down state.

In NIC switching mode (Logical IP takeover), you can execute any command along with activation and inactivation of physical interfaces.
[Changes]
Before modification
In NIC switching mode (Logical IP takeover), scripts are not called on activation and inactivation of physical interfaces.

The configuration file for Redundant Line Control function was added. For details see "3.6.10 Setting User command execution function."
[Changes]
Before modification
There is no corresponding script.
After modification
/etc/opt/FJSVhanet/script/service.sh
You can start or restart an arbitrary service or application in conjunction with the transfer path monitoring service for Redundant Line Control function (svc:/network/fjsvhanet-poll) or the service for Redundant Line Control function (svc:/network/fjsvhanet).
/etc/opt/FJSVhanet/script/monitor
You can start or restart an arbitrary service or application in conjunction with the self-checking function.

By setting a virtual gateway in GS/SURE linkage mode, applications for which local addresses cannot be fixed to virtual IP addresses become available.
[Changes]
Before modification
The requirement for user applications that can be operated in this mode is as follows:
The virtual IP address of Redundant Line Control function is set so that it is fixed as a local IP address using the bind function or others.
Thus, the Internet basic commands of Solaris such as ftp, telnet, and rlogin cannot be used in this mode.
After modification
The requirement for user applications that can be operated in this mode is as follows:
Application using TCP/IP

Specification of the MAC address which is used for the standby patrol can be omitted.
[Changes]
Before modification
You need to specify the MAC address when setting the standby patrol.
After modification
If you do not specify the MAC address when setting the standby patrol, the MAC address is automatically set.

RIP mode is removed.
[Changes]
Before modification
You can use RIP mode and Fast switching/RIP mode.
After modification
You cannot use RIP mode and Fast switching/RIP mode.

This function periodically monitors the state of the control daemon and virtual driver by the self-checking function.
[Changes]
Before modification
The state of the control daemon and virtual driver are not monitored.
After modification
The state of the control daemon and virtual driver are monitored. If an error occurred in operation, the error can be notified to the user.
Moreover, if the control daemon is stopped, it is automatically restarted.

The error output message (205) is changed.
[Changes]
Before modification
20501: operation error: mode can't be changed for dual stack inteface.
After modification
20501: operation error: mode can't be changed for dual stack interface.
