This section explains the settings when using the Dynamic Reconfiguration function.
See
For products provided with the DR function, see "2.3.2 DR (Dynamic Reconfiguration) linkage".
When building LAN environment for redundancy system using Redundant Line Control function, in order to replace or add the hardware without stopping the communication using Dynamic Reconfiguration, it is recommended to build the environment shown in "Figure 3.11 Recommended LAN configuration".
Figure 3.11 Recommended LAN configuration
Addition and deletion of hardware resource by a DR function are executed in an SB (System Board) unit. To continue communication when a DR command cuts off a system board, necessary to bundle actual interfaces on several different system boards as shown in a recommended configuration.
When using Redundant Line Control function other than GS/SURE linkage mode on the Solaris 10 OS, create one or more network configuration files on each system board. If the network configuration files are created only for one system board, services related to the network including Redundant Line Control function will not start in the case of the system board failure.
For details, see "(3) Checking the network configuration files of the operating system" of "3.2.2.1 Setup common to modes."
Note
Redundant Line Control function uses DR function to manage NIC device name, which allows dynamic replacement or expansion, on a single configuration file (/opt/FJSVhanet/etc/dr.d/hanet_dr_dev). Ensure the NIC device name is defined in the configuration file. If the NIC device name is not defined in the configuration file, DR function cannot be used for dynamic replacement or expansion. In such case, use the text editor to define the NIC device name in the configuration file to allow dynamic replacement or expansion.
The following shows the verification procedure of the configuration file (/opt/FJSVhanet/etc/dr.d/hanet_dr_dev).
# cat /opt/FJSVhanet/etc/dr.d/hanet_dr_dev hme qfe eri vge ge fjge fjgx fjqe fjgi ce ibdl |
For driver names which are not listed in the setting file (/opt/FJSVhanet/etc/dr.d/hanet_dr_dev), add driver names to the end of the setting file.
hme qfe eri vge ge fjge fjgx fjqe fjgi ce ibdl bge <- Added e1000g <- Added nxge <- Added fjxge <- Added |
