MULTI-PATH MANAGEMENT
First Claim
1. A multi-path management method of managing paths over which an IO is routed from a host to multiple logical volumes (LUNs) of a storage system, wherein the multiple LUNs of the storage system are mapped to the host, the method comprising:
- grouping LUNs with the same paths between the host and the storage system into a group of LUNs; and
using one path selection thread for all LUNs in the group of LUNs to manage the same paths.

Abstract
The invention discloses a multi-path management method and system for managing paths over which an IO is routed from a host to multiple logical volumes (LUNs) of a storage system, wherein the multiple LUNs of the storage system are mapped to the host, and the method comprises: grouping LUNs with the same paths between the host and the storage system into a group of LUNs; and using one path selection thread for all of LUNs in the group of LUNs to manage the same paths. The method and system lower the amount of work for path management and the amount of required resources.
