# Post-restoration tasks

During a restore operation, the appliance reconciles the data in the backup file with the current state of the managed environment. There are some discrepancies that a restore operation cannot resolve automatically; for example, if servers were added after the backup file was created. The network configuration on these servers is unknown to the appliance after a restore and could result in duplicate MAC addresses and World Wide Names (WWNs), as a result.

After a restore operation completes, you must manually resolve any remaining alerts and add these servers back into the appliance to eliminate the risk of duplicate IDs. You must also perform manual cleanup of hardware (servers, interconnects, and enclosures) if server profiles are forcibly unassigned or the hardware is forcibly removed without first being unconfigured.

Preventing duplicate IDs on the network after a restore

1. After a restore operation is complete, re-add any enclosure or server hardware added since the selected backup.

   | NOTE: For any enclosures added since the last backup that you decide not to re-add after the restore, avoid duplicate IDs by running the Onboard Administrator SSH command `clear vcmode` on these enclosures. Running this command ensures the virtual MACs and WWNs on the server blades in the enclosure have been cleared.

2. For any server profile alerts about the profile not matching the server hardware:

   1. Identify all server profiles with a mismatch-type of error message. Make a list of these server profiles and the assigned server hardware.

   2. Power off the server, and then unassign all of the server profiles individually. From the Server Profiles screen, select Actions→Edit, and then select Unassign from the server hardware drop down selector. Click OK.

   3. Select Actions→Edit again, and then reassign all of the documented profiles to the documented server hardware.

3. For any alerts about ID ranges, the Network administrator should examine the address and identifier ranges and edit them, if needed.

4. Re-create any profiles for the servers in any enclosures that were added in step 1.
