application client to a device server.
critical condition: An enclosure condition established when one or more elements inside the enclosure have failed
or are operating outside of their specifications. The failure of the element makes continued normal operation of at
least some elements in the enclosure impossible. Some elements within the enclosure may be able to continue
normal operation.
device: A mechanical, electrical, or electronic contrivance with a specific purpose.
device server: An object within a logical unit that executes SCSI tasks according to the rules of task management.
device service request: A request, submitted by an application client, conveying an SCSI command to a device
server.
device slot: A position into which an SCSI device may be inserted in an enclosure. The position provides appropriate
power, signal, and control connections to the SCSI device. The position may also provide mechanical protection,
locking capability, automatic insertion, visual device status indicators, and other features to manage the SCSI device
in the enclosure.
device type: The type of device (or device model) implemented by the device server.
element : An object related to an enclosure. The object can be controlled, interrogated, or described by the
enclosure services process. Defined elements are: devices; power supplies; cooling elements; temperature
sensors; door locks; audible alarms; enclosure services electronics; SCC electronics; nonvolatile cache;
UPS; display; keypad; SCSI transceivers; language element; communication port; voltage; current; SCSI
targets; SCSI initiators; and vendor-specific fields.
enclosure: The box, rack, or set of boxes providing the powering, cooling, mechanical protection, and
external electronic interfaces for one or more SCSI devices.
enclosure services: Those services that establish the mechanical environment, electrical environment, and external
indicators and controls for the proper operation and maintenance of devices within an enclosure.
enclosure services device: An SCSI device that monitors and controls enclosure services.
enclosure services process: The object that manages and implements the enclosure services. For an enclosure
services device the enclosure services process also implements the device server.
enclosure services processor: The physical entity that implements the enclosure services process.
information condition: An enclosure condition that should be made known to the application client. The condition is
not an error and does not reduce the capabilities of the devices in the enclosure.
indicator: A machine readable bit that optionally generates an externally visible indication when set.
initiator: An SCSI device containing application clients that originate device service requests to be processed by
device servers.
logical unit: A target-resident entity which implements a device model and executes SCSI commands originated by
an application client.
non critical condition: An enclosure condition established when one or more elements inside the enclosure have
failed or are operating outside of their specifications. The failure of the elements does not affect continued normal
operation of the enclosure. All SCSI devices in the enclosure continue to operate according to their specifications. The
ability of the devices to operate correctly if additional failures occur may be reduced by a non critical condition.
redundancy: The presence in an enclosure of one or more elements capable of automatically taking over the
functions of an element that has failed.
SCSI device: A device that may be connected to a service delivery subsystem and supports an SCSI application
protocol.
target: An SCSI device that receives SCSI commands and directs such commands to one or more logical units for
execution.
unit attention condition: A state that a logical unit maintains while it has asynchronous status information to report
to one or more initiators.
unrecoverable condition: An enclosure condition established when one or more elements inside the enclosure have
failed and have disabled some functions of the enclosure. The enclosure may be incapable of recovering or bypassing
the failure and will require repairs to correct the condition.
4.5 Configuring SNIA HBA API Library
The SNIA Common HBA API library was added to SMARTMon-UX in release 1.23. The library is an industry
standard library used to manage Fibre Channel Host Bus Adapters and discover SAN resources. It was developed
through the Storage Networking Industry Association (SNIA).
