StorageWorks Secure Path Terminology
Controller The hardware device that facilitates communication between a
host and one or more LUNs organized as an array. Secure Path
supports the HSG80 array controller. Each controller in a
HSG80 RAID system is identified by a unique World Wide ID.
HBA The I/O device (Host Bus Adapter) which serves as the interface
connecting a host system to the SAN (Storage Area Network).
Host The computer system on which the Secure Path server software
is running.
LUN The LUN is the actual unit number assigned to a device at the
RAID system controller.
Path A communication route that enables data and commands to pass
between a host server and a storage device.
State Attributes that describe the current operational condition of a
path. A path may exist in the following state(s):
■ online indicates a path that is currently servicing I/O
requests.
■ failed - a path that is nonfunctional and not actively
servicing I/O requests.
