4. [OPTIONAL] Check DeleteUnusedMaps to permanently delete unnecessary map files from each AMR. 3.9 What to do if an EM2100 Primary Fleet Manager Fails This section applies only if you installed a second EM2100, autosynchronized with the Primary Fleet Manager. In event of failure: 1. Using the SetNetGo interface, connect to the Management IP address for the Secondary Fleet Manager EM2100 appliance. 2. In the SetNetGo web interface System tab, open the Mode page. 3. Select Primary in the drop down menu. Click Apply . 4. Switch the Secondary appliance from Secondary to Primary. Use the drop-down arrow in the Autosync role field to select Primary . 5.
Click Apply (or click Reset to clear the form and restore its original values). The AMRs automatically reconnect to the new Primary appliance. The queue, configuration, and map data on the new Primary is identical to that of the old Primary, prior to failure. Depending on exact network configuration, it takes between 1-3 minutes for AMRs to reconnect and resume operation. The original (failed) Primary appliance can now be safely removed from the rack without caus- ing disruption to the fleet. The following considerations apply: l The new Primary operates on the same Fleet IP as the old Primary appliance. Do not reconnect the old Primary to the network without first reconfiguring it.
Doing so might cause a network IP conflict. l The failed Primary has the queue file, which is no longer current. Before putting the failed Primary back into service, you should manually clear the queue. See Manually Clearing (Flushing) the Entire Queue on page 181. 3.10 Remove and Replace EM2100 Appliances from Autosync This section describes how to remove an appliance from an Autosync configuration. Remove a Primary Fleet Manager Appliance from Autosync You might need to remove a Primary Fleet Manager appliance from an Autosync con- figuration while maintaining fleet operations.
For example, if the Primary appliance is gen- erating errors that indicate a potential failure or degraded performance. This procedure assumes that you do not make any changes to the software and data stored on the removed appliance. To safely remove an EM2100 Primary Fleet Manager appliance from an Autosync con- figuration, you must promote the Secondary appliance to the Primary role as covered in What to do if an EM2100 Primary Fleet Manager Fails on page 313.10 You can then safely remove the Primary as follows: 20569-020 Rev.
