Smarts IP domain is deleting all the devices and rediscovering the devices from scratch every time a discovery is run.
Smarts IP unmanaged status is not persistent because devices are being deleted and re-added back in.
How to prevent TSM from splitting the devices every time a discovery is run.
Smarts-10.1.x
Smarts DM -2.4
TCSA-2.x
To resolve this issue permanently across TSM domain restarts, do the following:
<BASEDIR>/IP/smarts/bin/sm_edit conf/discovery/topo-split/tsm.conf
IsSplitFromScratch = FALSE.
To change this setting on a running TSM domain (see Note statement):
<BASEDIR>/IP/smarts/bin/dmctl -s <TSM domain> put TopoSplit_Manager::TopoSplit-Manager::IsSplitFromScratch FALSE
<BASEDIR>/IP/smarts/bin/dmctl -s <TSM domain> get TopoSplit_Manager::TopoSplit-Manager::IsSplitFromScratch
