System and Method for Zoning of Devices in a Storage Area Network
First Claim
1. A method, in a data processing system, for automatically configuring zones of a storage area network (SAN), the SAN comprising one or more host systems and one or more storage devices, comprising:
- automatically assigning a host system of a chassis, in a storage area network (SAN) implementing a zoning protocol which comprises grouping and mapping components, to a first zone group of the SAN;
automatically assigning a second zone group of the SAN to a storage device in the chassis; and
automatically mapping the assigned first zone group and the second zone group to each other such that the host system is mapped to the storage device, wherein communication between the host system and the storage device is controlled based on the mapping of the assigned first zone group to the assigned second zone group.

Abstract
A system and method for performing zoning of devices, such as Serial Attached SCSI (SAS) devices, for example, in a storage area network (SAN) in which all host systems of the SAN are automatically mapped to all of the storage systems is provided. Mechanisms for automatically mapping backend storage enclosures to appropriate storage system controllers on the SAN are provided. The zoning is automatically performed based on whether ports/phys are coupled to host systems, storage systems, and whether there are storage system controllers associated with the storage systems. Based on the automatic zoning, mapping of the storage devices of the storage systems to the host systems may be automatically performed via zone permission tables. By automating the zoning, users that do not necessarily have a detailed knowledge of the storage device communication protocol or SANs may configure the SAN even if it utilizes a complex and large architecture.
