Change the Network Interface Card configuration and network settings
To provide the Managed IP service that is used to make the pair of High
Availability servers appear as one server to the external network, the
AutoStart software must know the local IP addresses of the ELAN Subnet
and Nortel Server Subnet (CLAN) of the pair of servers. If changes are
made to the ELAN Subnet IP address and Nortel Server Subnet IP address
on either server after the AutoStart software is installed, the AutoStart
software no longer works correctly. Depending on the state of the server
when the change is made, this can cause a failover to the standby server
or it can break the failover process.
Before changing any IP address or host name, Nortel recommends that you
take note of the IP addresses and host name. It is good practice to save them
to a safe location just in case you need them again (for example, if you need
to recover the server).
The IP addresses and host names are in the following locations:

Result: The CallPilot resource group is automatically brought
online on the standby High Availability server (CP1).
o. After the CallPilot resource group is online on CP1, restart CP2.
On CP1, do the following:
a. Launch the AutoStart Console.
b. Wait until node CP2 and both drvE and drvF are online/green in
the AutoStart Console.
c. Enable monitoring for the CallPilot resource group. For more
information, see
(page 214).
ELAN or CLAN IP addresses—Run the command ipconfig /all
command to check the current IP addresses.
Managed host name—Navigate to the E:\Nortel\HA folder and open the
AutoStart_Configuration.ini file to find the Managed host name. The
Managed host name is mapped to the Managed CLAN IP address.
Managed ELAN IP address (Virtual ELAN IP address)—This IP address
is also saved in the E:\Nortel\HA\AutoStart_Configuration.ini file.
