Issue/Introduction

Symptoms:

• 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.

Environment

Smarts-10.1.x

Smarts DM -2.4

TCSA-2.x

Cause

TSM is splitting the devices every time a discovery is run.

Resolution

To resolve this issue permanently across TSM domain restarts, do the following:

1. Open the Smarts IP tsm.conf configuration file in sm_edit:
   
   <BASEDIR>/IP/smarts/bin/sm_edit conf/discovery/topo-split/tsm.conf
   
    
2. Set IsSplitFromScratch = FALSE.
    
3. Restart the TSM domain.

To change this setting on a running TSM domain (see Note statement):

1. Run the following dmctl command:
   
   <BASEDIR>/IP/smarts/bin/dmctl -s <TSM domain> put TopoSplit_Manager::TopoSplit-Manager::IsSplitFromScratch FALSE
   
    
2. Confirm the change with the following dmctl command:
   
   <BASEDIR>/IP/smarts/bin/dmctl -s <TSM domain> get TopoSplit_Manager::TopoSplit-Manager::IsSplitFromScratch

Additional Information

You can do both the permanent change and change the setting on a running domain.
