Abstract

A computing device includes an interface configured to interface and communicate with a dispersed storage network (DSN), a memory that stores operational instructions, and a processing module operably coupled to the interface and memory such that the processing module, when operable within the computing device based on the operational instructions, is configured to perform various operations. The computing device detects a commissioned storage unit (SU) that was previously non-commissioned and identifies SU(s) that include commissioned SUs among the SUs. The computing device then identifies a SU topology of the SU(s) and selects a subset of the SU(s) based on the SU topology. The computing device then obtains SU address range assignments of the subset of the SU(s) facilitates assignment of a SU address range for the commissioned SU that was previously non-commissioned within the SUs based on the SU address range assignments of the subset of the SU(s).
