Replacing a Collector

Prerequisites:

Prepare a new collector (that is, the replacement collector) that will replace the existing one, including:

• Configure the management port IP address on the replacement collector using the Admin Shell with SSH and the following command:
  new_collector_admin > configure server

• Install the standalone license on the replacement collector. For more information, see 5th Step: Installing the Operations Center Collector Licenses.

To replace a collector in an Operations Center environment, complete the following:

1. In the NetMRI UI of the Operations Center, click the Settings icon > Setup >Tunnels and Collectors.
2. To replace the collector, click Actions > Collector Replacement.
3. Change the serial number of the existing collector to that of the replacement collector.
4. Click OK.
5. In the administrative shell, log in to the existing collector and then deregister it.
   old_collector_admin > deregister

6. Register the replacement collector to the Operations Center IP Address, and define the Operations Center Network to which the collector belongs.
   
   new_collector_admin > configure tunclient

+++ Configuring Tunnel Registration Settings
Registration Server/IP [example.com]: tunserver IP address or FQDN
Registration protocol (http|https) [https]:
Registration username: tunserver login
Registration password: tunserver password
   
   After executing the configure tunclient command, the Operations Center automatically pushes all previous collector settings to the replacement collector and the collector begins its normal discovery tasks.
   
   
7. In the NetMRI UI of the Operations Center, click the Settings icon > Setup > Scan Interfaces and change the scan IP address for that of the new collector.
8. To verify that the replacement collector status is Connected, click the Settings icon > Setup > Tunnels and Collectors and then check the collector status in the Status column.

You can use SSH to log in to the Operation Center's Admin Shell, to view a listing of the OC system and the collectors. The show tunserver command shows each collector's status in its listing.
