Abstract
A method, computer program product, and computer system are provided for configuring asymmetric logical unit access (ALUA) states for paths in a multipath storage system. The method includes providing storage feature indications for paths between a host and a volume, wherein the storage features are provided by the storage system end of the path. The method configures ALUA states for available paths between a host and a volume based at least partially on the storage feature indications to direct host operations to one or more paths based on available storage features at the storage system to prioritize paths with selected storage features. Configuring ALUA states for available paths may include configuring ALUA states for paths for a given host based on parameters of the host and storage feature of the path required for the host parameters.
