Symptom
- FTD(s) unable to register to recently migrated secondary FMC.
- FMCs (primary/secondary) throwing error "Peer Management Center has fewer devices registered"
Conditions
- FMC recently upgraded to 7.2.0+
- Secondary FMC recently migrated
FTD's had HF applied which cause the registration issues to Standby FMC because of unexpected sw_version change in EM_peers table on FTD's
Workaround
Fix sw_version value in EM_peers table on all FTD's that are affected by recently applied hot fixes.
Further Problem Description
In this specific case sw_version is set to 7.2.2.1 in EM_peers table while in ims.conf it retains the correct value of "7.2.2".
Need to improve HF installation scripts.
Mitigate version mismatch discovered on FTD's automatically.
To cleanup secondary entry on FTD (if added incorrectly) and fix EM_peers sw_version value attached script fix_em_peers_versions.pl can be used
