Symptom
A backup of the Secure Firewall Management Center (FMC) may fail with the following error message sequence appearing in the backup logs ( /var/log/backup.log ):
---
exit status:Registration Blocking
Entering: main::fail
Entering: main::update_status
Update Task: Registration or CSM state are blocking Backup
---
A similar error may appear for the backup task in the notification area of the FMC GUI.
The /var/log/CSMAgent.log log file may start to show entries containing the following (for a variety of different processes):
---
'description' => 'Authorization Failure: Cannot retrieve session ids from request header'
---
Conditions
Possible causes of the conditions that in turn cause the device registration check part of the FMC backup to fail include:
* A version and build of the Cisco Secure Dynamic Attributes Connector (CSDAC) affected by defect CSCwf03852 has been integrated with the FMC.
* The FMC backup runs at the same time as (and may interfere with) another scheduled task.
Workaround
1. Log into the FMC CLI.
2. Go to expert mode:
expert
3. Restart the DCCSM process (when prompted, enter the password for the logged-in user):
sudo pmtool restartbyid DCCSM
4. Attempt the FMC backup again from the FMC GUI.
