Environment

VMware Smart Assurance - SMARTS

Cause

The error message is the result of trying to split a topology with X number of devices into X+1 number of IP domains.  For example, trying to split a TSM topology of 5 devices into 6 AM-PM domains.

Resolution

To resolve this issue, ensure that you have enough devices in the TSM topology so when it performs a split, each of the domains it is splitting to will be populated with at least one device. If you have fewer devices in Smarts TSM than the number of IP domains it is splitting to, change the NumberOfDomains parameter in tsm.conf to resolve this.
