internal hardware component failure such as a disk drive crash. If both appliances are
affected, all fleet operations terminate.

6.6 Remove and Replace Enterprise Manager 2100 Appli-
ances from Autosync
This section describes how to remove an appliance from an Autosync configuration.
Remove a Primary Appliance from Autosync
You might need to remove a Primary appliance from an Autosync configuration while main-
taining fleet operations. For example, if the Primary appliance is generating 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 Enterprise Manager 2100 Primary appliance from an Autosync con-
figuration, you must promote the Secondary appliance to the Primary role as shown in 6.6
You can then safely remove the Primary as follows:
1. Verify that fleet operations are normal and job processing is on schedule.
2. Reconfigure the Primary appliance as a Secondary appliance. See: Configure the Sec-
ondary Appliance on page 57.
MobilePlanner and fleet AIVs might lose their network connection to the appliance.
3. Reconfigure the Secondary appliance [2] as the Primary appliance. See: Configure the
Primary Appliance on page 56.
4. Power off the Secondary (failing) appliance.
5. The new Primary appliance now indicates that Autosync is disabled (it is now a stan-
dalone appliance.)
6. Verify that MobilePlanner can connect to the Fleet IP, that fleet AIV operations resume,
and jobs are processed as scheduled.
To restore a removed appliance to its role as Primary appliance, or to replace it with a new
appliance:
1. Verify that fleet operations are normal and job processing is on schedule.
2. If you have removed any network cables, replace them as shown in Figure 5-5.
3. Power on the (now Secondary) appliance. (This should not affect fleet operations or Eth-
ernet connections to MobilePlanner and AIVs.)
4. Reconfigure the Primary appliance as a Secondary appliance. See: Configure the Sec-
ondary Appliance on page 57.
MobilePlanner and fleet AIVs might lose their network connection to the appliance.
