Abstract
A cluster includes a fabric, a host coupled to the fabric, an I/O enclosure coupled to the fabric, and a subnet manager. The subnet manager performs a topology discovery of the cluster and detects ports associated with the fabric. The subnet manager computes a minimal spanning tree for the cluster, which connects every port to every other port through a single path. The subnet manager assigns a single base LID to each port and programs the assigned LIDs into forwarding tables in the fabric. Additional LIDs are reserved for each port while the single base LID is assigned to each port such that the fabric is functional and connected when the subnet manager is performing a path analysis of the cluster.
