1. Overview of HDLM
HDLM is a software package that manages paths between a host and a storage system.
HDLM is designed to distribute loads across multiple paths and will switch a given
load to another path if there is a failure in the path that is currently being used, thus
improving system reliability.
This chapter gives an overview of HDLM and describes its features.
