On an environment where GS/SURE Linkage mode is operating on the cluster system, activate a standby node of a virtual interface (operation mode 'n') from the system startup.
[Changes]
Before modification
During the system starts up, the virtual interface on standby node (operation mode 'n') will not be activated. Instead, the physical interface will be activated.
After modification
During the system starts up, the virtual interface on standby node (operation mode 'n') will be activated. But, the physical interface will not be activated.
[Notes]
You need to pay attention to applications which are aware of the interface name during the communication. Previously, physical interface names have interface names according to each NIC type, such as "hme0" or "hme1", on the standby node. However, they are activated by a virtual interface name, such as "sha1" or "sha2" activate from this version.

During system configuration or activation of virtual interfaces, Redundant Line Control function now verifies for the consistency of network address for configured virtual IP address and physical IP address. In the case where invalid network address of virtual or physical IP address is configured, it will output the following warning.
Warning:
hanet: 35800: warning: the same network addresses are inappropriate.
Note
Before the hanetconfig command defines virtual interfaces, please define sub-net mask as a /etc/inet/netmasks file. A warning message may be outputted when sub-net mask is not being defined in advance.
[Changes]
Before modification
It did not check for the consistency of network address for the configured IP addresses.
Network Address | Redundant Mode | Results | |
Network address of each interface (physical interface, virtual interface, etc.) is consistent | NIC Switching mode | Valid configuration | No warning message |
Fast Switching mode | Invalid configuration | ||
RIP mode | |||
GS/SURE linkage mode |
After modification
Verifies for the consistency of network address for the configured IP addresses.
Network Address | Redundant Mode | Results | |
Network address of each interface (physical interface, virtual interface, etc.) is consistent | NIC Switching mode | Valid configuration | No warning message |
Fast Switching mode | Invalid configuration | Outputs warning message (No.358) | |
RIP mode | |||
GS/SURE linkage mode |
[Notes]
If warning message (No.358) is displayed while running the following commands, check the IP address or net mask value (/etc/netmasks) configured on the physical and virtual interfaces to find no mistake is set. Note that, command process continues execution regardless of the warning messages.
/opt/FJSVhanet/usr/sbin/hanetconfig create
/opt/FJSVhanet/usr/sbin/hanetconfig modify
/opt/FJSVhanet/usr/sbin/hanetconfig copy
/opt/FJSVhanet/usr/sbin/strhanet
/opt/FJSVhanet/usr/sbin/hanetnic add
/opt/FJSVhanet/usr/sbin/hanethvrsc create
When the definition error of a network address is detected at the time of system starting or RMS starting, a warning message may be output to syslog instead of a standard error (stderr).
