Virtual NIC mode is added.
Before modification
Virtual NIC mode is not provided.
After modification
Virtual NIC mode is added.
(2) Configuration of GS load sharing
In GS linkage mode, in addition to conventional GS of hot-standby configurations or single system configurations, protocols used on GS in load sharing configurations are supported.
Before modification
No communication is possible with GS in a load sharing configuration, even when using GS linkage mode.
After modification
Communication is possible with GS in a load sharing configuration when using GS linkage mode.
GS load sharing configurations are supported by default. Therefore, you do not need to change GLS parameters. In addition, load sharing configurations are valid even when the following parameters are set:
/etc/opt/FJSVhanet/config/ctld.param
#
# HA-Net Configuration File
#
# Each entry is of the form:
#
# <param> <value>
#
observ_msg 0
observ_polling_timeout 180
max_node_num 4
load_sharing 1 |
(3) Options for UDP application
Settings of arpflag parameters are not required in environments in which frequently transmitting UDP applications (*1) use NIC switching mode.
Note *1: For example, applications that implement heartbeat processing between nodes
Before modification
For using frequently transmitting UDP applications, "arpflag 1" must be specified.
After modification
For using frequently transmitting UDP applications, "arpflag 1" is not required to be specified.
Frequently transmitting UDP applications are supported by default. In addition, they are valid even when the following parameters are set:
/etc/opt/FJSVhanet/config/ctld.param
#
# HA-Net Configuration File
#
# Each entry is of the form:
#
# <param> <value>
#
observ_msg 0
observ_polling_timeout 180
max_node_num 4
arpflag 1 |
(4) Conditions to output the message in Fast switching mode
The condition to output the console message (message number: 990) for Fast switching mode has been changed.
Console output message:
hanet: 99080: line status changed: all lines disabled: (devicename: interface1=Down, interface2=Down, ...) |
Before modification
This message is output if no communication target is recognized.
After modification
This message is output if at least one communication target is recognized and then the target becomes unrecognizable.
The console output message (message number: 990) is displayed if the "Line status message output (s)" is set to "ON" by using the "hanetparam" command with the "-s" option (The default value is OFF).
This change of the condition to output the message is applied for startup of the system or execution of the "strhanet" command. In cases other than above (for example, communication or switching), no changes are applied for conditions to output the message.
(5) Order to start and stop of GLS service
Order to start and stop of GLS service (hanet) is changed on startup of the operating system.
Before modification
Start with S32hanet. Stop with K68hanet.
After modification
Start with S11hanet. Stop with K89hanet.
The virtual IP address of GLS which is not registered in a cluster is activated on startup of GLS service (hanet). The virtual IP address is deactivated on stop of GLS service. In addition, the virtual IP of the Virtual NIC mode is activated with the S10network.
(6) Conditions to output the message for a NIC bundled in the GLS virtual interface
In Fast switching mode, NIC switching mode, or GS linkage mode, when the virtual interface of GLS is activated and a physical interface cannot be UP, the following message is output to the system log:
hanet: ERROR: 853XX: physical interface up failed. nicname=ethY name=shaZ
Before modification
The error message (message number: 853) is not output to the system log.
After modification
The error message (message number: 853) is output to the system log.
For the virtual NIC mode, the following message is output to the system log:
hanet: WARNING: 91180: link down detected: the physical interface link is down. (shaX: ethY)
