■ The connection is bound to a storage port WWN. If the fiber optic cable is
disconnected from the storage port, the server-to-storage connection is
automatically reestablished when the port cable is reconnected. The
connection is also automatically reestablished if the storage port is cabled
through a different managed product port.
Access can also be controlled at the storage device as an addition or
enhancement to redundant array of independent disks (RAID) controller
software. Data access is controlled within the storage device, and server HBA
access to each LUN is explicitly limited (access is blocked by default).
Storage-level access control:
■ Provides control at the storage port and LUN level, and does not require
configuration at the server.
■ Is typically proprietary and protects only a specific vendor’s storage devices.
Storage-level access control may not be available for many legacy devices.
Note: Refer to the HP professional services organization before establishing persistent
binding and when establishing access control features at the storage device.
Zoning Concepts
Zoning is configured by authorizing or restricting access to name server
information associated with device ports that attach to product ports. A zone
member is specified by the number of the product port to which a device is
attached, or by the 8-byte World Wide Name assigned to the host bus adapter or
Fibre Channel interface installed in a device. A device port can belong to multiple
zones.
Zoning concepts include:
■ Zones
■ Default Zone
■ Zone Sets
■ Zone Library
■ Active Zone Set
