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 monitoring nodes.
Refer to "6.1 Stop."
Set up the IP address.
Execute the following commands on a node (a management server, a monitoring node) where the 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> indicates mip. Set up the virtual IP address.
<httpip> indicates httpip. Set up the virtual IP address.
Change the management server settings.
Change the management server settings on all the management servers and monitoring nodes if the node changed in Step 2 is the cluster management server.
# /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>
For the IP address indicated as <IP address of primary management server> and <IP address of secondary management server> in the reference, set up mip for each management server.
Restart Web-Based Admin View on all the management servers and monitoring nodes.
Refer to "6.2 Restart."
Note
Only IP (IPv4 or IPv6) addresses can be set to the primary management server, the secondary management server, and httpip. Note that IPv6 link local addresses cannot be set to these servers.
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 Web-Based Admin View screen, 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 a 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 100Start Web-Based Admin View.
Start Web-Based Admin View on all the management servers.
# /etc/init.d/fjsvwvbs start # /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."
