C.3 SWAPPING OUT AN IPATH AGILITY CONTROLLER
Once Agility devices have been configured to run with an iPATH Agility Controller, their default IP addresses are automatically
changed as part of the installation process. In this state the Agility devices become undetectable to any new iPATH Agility
Controller that does not have access to the database of devices. Therefore, if an existing iPATH Agility Controller needs to be
replaced within an installation, follow one of the basic procedures given here to smooth the transition.
The correct procedure to use depends on whether you are using a solo iPATH Agility Controller (firmware versions below 3.0 can
only be used as solo servers) or a pair of iPATH Agility Controllers in a primary/backup redundancy arrangement:
C.3.1 FOR SOLO IPATH AGILITY CONTROLLERS
1 Before connecting the new iPATH Agility Controller to the main network, connect the new iPATH Agility Controller to a network
switch that is isolated from the main network.
2 Use a computer connected to the same switch to login to the new iPATH Agility Controller management suite.
3 Set the Role entry to Solo.
4 Set the IP address of the new iPATH Agility Controller to match that of the original unit.
5 Restore a backup file of the original iPATH Agility Controller database to the new device.
6 Remove the original iPATH Agility Controller from the network. Connect the new iPATH Agility Controller in its place and
power up.
7 All the devices will appear as offline. Using a paperclip, perform a factory reset on all the Agility endpoints so as they acquire
the new certificate and keys. All Agility units require a minimum of firmware version 3.3.
C.3.2 FOR DUAL IPATH INSTALLATIONS USING REDUNDANCY
The correct procedure depends on which iPATH Agility Controller has failed:
Primary server failure
1 Promote the backup server to be the primary server.
2 Delete the failed server from the database.
3 Replace the faulty primary iPATH Agility Controller with a replacement unit that has the same license version and has its default
factory settings in place.
4 The replacement server will begin communicating with the primary server and download the database so that it can operate as
the backup server. This process may take ten minutes.
5 Reboot the Agility endpoints at the earliest opportunity.
Backup server failure
1 Delete the failed server from the database.
2 Replace the failed backup server with a new unit that has the same license version and has its default factory settings in place.
3 The replacement server will begin communicating with the primary server and download the database so that it can operate as
the backup server. This process may take ten minutes.
4 Reboot the Agility endpoints at the earliest opportunity.
Warning: If step 4, rebooting the Agility endpoints, does not happen then the Agility endpoints will be offline if a failover occurs
and will need to be factory reset with a paperclip.
