About this task
If you need to change the IP address or hostname of a dedicated
primary EPM server after the EPM software is installed, or if you need to move the
primary EPM software to a new server that has a different IP address
and hostname, you need to change the information stored in the Experience Portal database to match the new system configuration.
Procedure
- Log on to Linux on the Experience Portal Primary EPM server.
If you are an Avaya Services representative, and use Avaya
Enterprise Linux, or if the Avaya Service accounts are installed on
this server, log on to the local Linux console as root.
Otherwise, log on remotely as a non-root user, and then change
the user to root by entering the su - root command.
-
Stop the vpms service by
entering the systemctl
stop vpms command.
-
If you want to change the
hostname or IP address of the current server, do the following:
-
Use the nmtui tool as described in the Red
Hat documentation.
-
Open the /etc/hosts
file in an ASCII editor and change the IP address and hostname to the
values you specified with the configuration tool.
-
Reboot the EPM server.
-
Stop the vpms service by entering the
systemctl stop vpms command.
-
Navigate to the
do_UpdateHost script directory by entering the
$AVAYA_HOME/Support/UpdateHostAddress command.
-
Enter the bash
do_UpdateHost command to change the hostname in the database to
the hostname of the current server.
-
Start the vpms
service by entering the systemctl start
vpms command.
-
If the Primary EPM hostname and IP exists as an entry in the
/etc/hosts file on the Auxiliary EPM and MPP servers,
update these entries with the new hostname and IP address of the Primary
EPM
Next Steps
Reconnect the existing MPP servers and Auxiliary EPM servers with the Primary EPM server. For more information, see:
