6.7 What to do if an EM2100 Primary Appliance Fails
6.7 What to do if an EM2100 Primary Appliance Fails
This section applies only if you installed a Secondary Enterprise Manager appliance, auto-
synchronized with the Primary.
In event of failure:
1. Using the SetNetGo interface, connect to the Management IP address for the Secondary
appliance.
2. From SetNetGo on the Secondary appliance, select
Software and then Autosync .
3. Switch the Secondary appliance from Secondary to Primary.
Use the drop-down arrow in the Autosync role field to select Primary.
4. Click Apply or click Reset to clear the form and restore its original values.
The AIVs 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 AIVs 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The failed Primary has the queue file, which is no longer current.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 70.
6.8 What to do if an EM1100 Autosync Appliance Fails
This section applies only if you have a two EM1100 appliances in an Autosync configuration,
and either the Primary or the Secondary fails and you must replace it with an EM2100. In
mixed-model configurations, the EM2100 always operates as the Primary appliance, while the
EM1100 always operates as the Secondary appliance.
If you have a mixed-model ( EM2100) Autosync configuration, it cannot support
multiple software versions. Both appliances must run the same version that is running on an
EM2100, and you must upgrade the EM1100 to that version.
Configure an EM1100 to EM2100 Configuration
Use the following procedure to replace a failed EM1100 Appliance with a replacement
EM2100.
1. Power off the failed appliance and disconnect its power cable.
2. Remove the networking cables from the failed EM1100 appliance and physically
remove it.
