2.3.2 Virtual NIC mode

After setting Virtual NIC mode of GLS, take following steps to set Web-Based Admin View.

Stop Web-Based Admin View on all the management servers and monitored nodes. Refer to "6.1 Stop."
Set up an IP address.
Execute the following commands on the management servers and monitored nodes where GLS virtual IP address needs to be set.
# /etc/opt/FJSVwvbs/etc/bin/wvSetparam mip <mip>
# /etc/opt/FJSVwvbs/etc/bin/wvSetparam httpip <httpip>
<mip> is mip, which sets the virtual IP adress.
<httpip> is httpip, which sets the virtual IP adress.
Change the management server settings.
If the changed monitored node acts as a cluster management server as well, you must change the management server settings on all the management servers and monitored nodes.
# /etc/opt/FJSVwvbs/etc/bin/wvSetparam primary-server <primary management server IP address>
# /etc/opt/FJSVwvbs/etc/bin/wvSetparam secondary-server <secondary management server IP address>
Specify mip of the management servers respectively for each IP address of <primary management server IP address> and <secondary management server IP address>.
Restart Web-Based Admin View on all the management servers and monitored nodes.
Refer to "6.2 Restart."

Note

Only the IP address can be set to the primary management server, the secondary management server, and httpip.

The virtual NIC mode takes 1 to 300 seconds, (default: 1-17 seconds) from the failure occurrence to switchover, and the connection between the client and the management server might be dropped during this time.

In such a case, close the active browser, and reconnect to the management server after confirming switchover completion. Otherwise, the connection to the available management server can be established by clicking [Yes] to the 0007 message if it is displayed.

If the time of monitoring connection (default: 10 sec.) between the client and the management server is extended in the environment setup for Web-Based Admin View, the connection can be sustainable when the NIC switching is done. On the other hand, the failure detection of the session is delayed in the event of node stop or panic disorder. Based on this fact, change the time interval to monitor the connection between the client and the management server (Client - management server connection time).

For Client - management server connection time, be aware of setting the value (1-300 sec.) exceeding the time from occurrence of a NIC failure to completion of switchover.

For the setup of Client - management server connection time, refer to "Chapter 4 Environment settings." In the screen of the environment setup screen, up to 60 seconds can only be set at the maximum. Using wvSetparam command allows a user to set 60 seconds or more.

Setup of Client-management server connection time

Stop Web-Based Admin View.
Stop Web-Based Admin View on all the management servers.
```
# /etc/init.d/fjsvwvcnf stop
```
```
# /etc/init.d/fjsvwvbs stop
```
Set up Client - management server connection time.
Refer the example below to execute the following command on all the management servers:
Example: When changing Client - management server connection time to 100 seconds
```
# /etc/opt/FJSVwvbs/etc/bin/wvSetparam keep-time 100
```
Start Web-Based Admin View.
Start Web-Based Admin View on all the management servers.
```
# /etc/opt/FJSVwvbs/etc/bin/wvCntl restart
```
```
# /etc/init.d/fjsvwvcnf start
```

Dynamic operation of secondary management server

The secondary management server can be dynamically operated in the environment where the network interface used with Web-Based Admin View is configured to be redundant by using Virtual NIC mode of GLS.

For the setting to operate the secondary management server dynamically, refer "7.4 Secondary management server automatic migration."
