Introduction
This document describes how to add missing components in the the Unified Communications Manager IM and Presence (IM&P).
Background
Missing components from the Unified Communications Manager IM and Presence (IM&P) when Disaster Recovery System (DRS) has missing components, must be found and added.
Components in IM&P Nodes
The DRS which provides the capability to perform a data backup for all the IM and Presence nodes. Occasionally, due to unexpected internal server errors the IM and Presence nodes can be missing some of the components that cause the DRF backup not to be successful. The IM and Presence nodes must have the these components in order to perform a backup task successfully.

The DRS backs up all of its components automatically when they are all complete, however certain times the IM and Presence nodes can be missing some components and this issue causes the backup process to fail. If that is the case, you can see this error in the DRF logs.

Missing Components
In order to see if the IM&P components are complete run the the this command in both nodes through the IM&P CLI .
- utils disaster_recovery show_registration nodename
Where nodename is the IP address of the node or its name.
List of Commands for Missing Components
If there are missing components in a node it is required to create a root account via CLI to add manually the missing components through the use of the certain commands, each for every missing component. The list shows the commands with their specific path for every component it is required to run the corresponding command for each one of the missing components in the right node:

After the ones that were missing are added, they must be displated after the command runs again.
- utils disaster_recovery show_registration nodename
After the task is complete the IM&P node backup task must start.
On the other hand, if there are more components added than expected the DRF backup task fails as well. That is caused by the Cisco bug ID CSCuv53092 in that case the workaround referred in the defect fixes the issue.
Refer to Cisco bug ID CSCuv53092.
