Asymmetric Logical Unit Access (ALUA), also known as Target Port Groups Support (TPGS), is a set of SCSI concepts and commands that define path prioritization for SCSI devices. ALUA is a formalized way to describe SCSI port status, and access characteristics. In short, it describes paths as fast, slow, or down and the transitions between these states in a standards-compliant manner. This standard is designed to define the protocol on how multipath IO should be managed between hosts and storage devices. It will also reduce vendor-specific coding and complexity.
