You can force SAM and IP to synchronize manually using the following command:
<basedir>/smarts/bin/dmctl -s <sam_server> invoke GA_DaemonDriver::<am_server>_Topo-Driver start
Example:
<am_server> = INCHARGE-AM
<sam_server> = INCHARGE-SA
dmctl -s INCHARGE-SA invoke GA_DaemonDriver::INCHARGE-AM_Topo-Driver start
You can also initiate a discovery of one or all devices in the underlying IP server in order to force a re-sync.
