Standby comes up with old configs
We have a pair of LTM 1500's configured as active-standby pair, running BIG-IP Version 9.4.3 1.4. Config sync completes successfully, and I can see that the /config/bigip.conf file is identical after sync.
However, the running configuration on the standby is old and bears little relation to the active peer. There was a data center move, and IP renumbering that happened before I started here.
Last night I attempted to fail over to the standby, after performing a sync and confirming that the bigip.conf file matched on the two systems. My expectation was that when the standby became active, it would load the correct config from config sync. However, the standby system took over using its old config, which is completely broken in the new environment. I was forced to fail back to the primary system.
It seems that the standby is holding on to its old config, despite receiving config sync from the primary. Is there some way I can ensure that the standby gets loaded with the correct configuration?
Should I do a "b config install my_active.ucs" on the secondary unit to ensure the configs are synced?
Any suggestions appreciated!
