This section explains the procedure for changing the host name and the IP address of the takeover network resource.
Operation flow
Operation Procedure:
Stop RMS of all the nodes.
If RMS is running, see "7.2.1.2 Stopping RMS" and stop RMS.
Change the settings in the "/etc/hosts" file.
Change the host name and IP address in the "/etc/hosts" file on all the nodes that use takeover network resource.
Change the settings in the "/usr/opt/reliant/etc/hvipalias" file.
See "6.7.3.6 Setting Up Takeover Network Resources" and change the settings in the "hvipalias" file on all the nodes that use takeover network resource.
There are two items that may need to be changed as follows.
<node name> : When the host name is changed, the CF node name also needs to be changed. Change the value of this field to the modified CF node name. <takeover> : Change this host name when the host name associated with the takeover IP address was changed.
Change the setting with the RMS Wizard.
Execute the "hvw" command in any node that is part of the cluster system.
Change the host name settings for the takeover network resource from the GUI menu displayed in the RMS Wizard.
Note
For changing only the IP addresses of takeover network resource but not the host names, it is not necessary to use the RMS Wizard.
