The ATL M1500 tape library can contain up to two tape drives and up
to 21 DLT/SDLT cartridges and 25 LTO cartridge. The ATL M1500
library is controlled by a host computer via a SCSI differential bus
using the SCSI-2 medium changer command set. There is also a RS-232
diagnostic port interface.
The ATL M1500 Prism Architecture™ allows for easy conversion from
the SCSI host interface to a Fibre Channel host interface by installing
the FC310 Router option. This document is provided to end users of
the ATL M1500 library to describe the FC310 Fibre Channel host
interface option.
For a complete description of the ATL M1500 library operating
procedures, see the Quantum ATL M1500 User’s Guide (PN 6421000).
Fibre Channel
Description
Fibre Channel is a serial data transfer architecture for use with
0
computers and mass storage devices. Fibre Channel is rapidly
emerging to challenge SCSI as the interface of choice for host-tostorage applications.
Fibre Channel advantages include:
•Connection distances with the FC310 option of up to 500 meters
•1 GB/S data transfer rates
•Support for up to 126 devices on a loop
•Support for 24-bit addressing for over 16 million devices in
point-to-point mode or fabric, when using a Fibre Channel switch
or multiple Fibre Channel switches.
•Operating system independence
•Interconnect flexibility
•Fibre Channel fabric switches provide full direct connectivity
between all ports on a network, which can increase the total
throughput of all devices on a network.
FC310 Router
Operation
Once the FC310 Router SCSI to Fibre Channel option is installed and
0
tested, the library operates exactly as a ATL M1500 library with a SCSI
host interface. User operation of the library via the graphical user
interface (GUI) panel is unchanged.
Key to Successful
Configuration of the
FC310 Option
0
The FC310 Fibre Channel Option must be configured using the
homebred FC310 Prism Router Services software. The key to
successfully configuring the FC310 Option is to:
•Know exactly how the SCSI cabling in the library is configured
including how many:
aSCSI buses are present in the library
bSCSI devices are connected to each bus
•Use the FC310 Prism Router Services software to create a Map file
identifying which SCSI devices are electrically connected to which
Fibre Channel ports on the FC310 board

12Commonly Used FC310 Services Software Commands for the ATL M1500 Library
The FC310 Services Software is resident on each FC310 Router board,
and is used to configure the router for use in the Quantum ATL M1500
library. The software uses a Command Line Interface (CLI) that is
usable with any PC and a terminal emulation program such as
HyperTerminal or ProComm.
FC310 Service
Software Operation
The Command Line Interface provides access to the FC310 services
0
through a set of ASCII-based command lines. Commands have four
types of operation:
•Immediate—cause an immediate action; not preceded by a get or
set operation.
•Get—returns the current value of a parameter or setting. This
command may be abbreviated to “g”.
•Set—changes the value of a parameter or setting. This command
may be abbreviated “s”, and does not take effect until a
SaveConfiguration command is sent.
•Usage—if the form of an operation cannot be determined, it is
assumed to be the “Usage” form and a brief help message is
displayed.
The commands are not case sensitive.
Decimal numbers may be entered as raw numerical input, such as 123.
Octal numbers must be preceded by the number 0, for example 0713.
Hexadecimal numbers must be preceded by the C-style of 0x prefix,
such as 9x1FA4.
Quoted strings are treated as a single parameter for any command
which expects character input, regardless of space in the string.
Several non-immediate commands require a
SaveConfiguration before
their modified parameters take effect. When such a command is
executed an asterisk appears next to the command line prompt.
Set the switches which control the filtering performed when
displaying events. Switches have the following meanings and
settings:
(subsystem) switch: mask that controls which subsystem
events are displayed. The mask is a byte value with the
following bit patterns corresponding to the currently
supported subsystems:
0x01 FCP Processor /i960
Interaction
0x02 SCSI Processor/i960
Interaction
0x04 Ethernet (Future)
0x20 NVRAM & Flash
To display the events from several different subsystems, use a
mask value equal to the logical OR of the corresponding
subsystem values. To display events from all subsystems enter
the value 3Fh for the mask.
(event_level) switch: mask that controls what reporting level
events are displayed. The mask is a byte value with the
following bit patterns corresponding to the currently
supported reporting levels:
set dispevent [subsystem]
[event_level] [status]
get dispevent
3Fh
3Fh
0x01 Info; general information
0x02 Warning; unexpected situation/condition
0x04 Critical; operation limited/curtailed
0x08 Failure; hard failure
0x10 Other; otherwise not categorized
0x20 Debug; tracking events
To display events from several different reporting levels, use a
mask value equal to the logical OR of the corresponding
reporting levels. To display events for all reporting levels enter
the value 3Fh for the mask.
(status) switch: has the following two values which correspond
to the status of the events to be displayed:
all All events, regardless of their status values are displayed.
ngood Only events with a status other than good are displayed.
Sets the switches which control the filtering performed when
logging events. The switches have the following meanings and
settings:
(enabled | disabled) switch: controls whether or not events
logging is enabled or disabled.
(subsystem) switch: same as switch for DispEvent in previous
section
(event_level) switch: same as switch for DispEvent in previous
section
(status) switch: same as switch for DispEvent in previous
section
ClearEvent (Immediate)
Clears the contents of the event
log.
DisplayEvent (Immediate)
Displays the current contents of
the event log. The log is filtered by
the current switch settings as
described in the DispEvent
section. If the optional all is
selected, the display filtering is
temporarily suspended and all
logged events are displayed.

RestoreConfiguration
(Immediate)
Displays version numbers and
other product information for key
components within the FC310.
Displays a list of available
commands. When the optional
command name is present,
detailed command-specific
information is displayed.
Restore to factory default
configuration or the last saved
configuration. The new
configuration must be saved to
take effect.
Save the new configuration. If a
firmware restart is required to
make the change, the user is
prompted to confirm the restart.
The user can override the
confirmation request by indicating
the override value on the
command line.
Reserve (Immediate)
Reservation of the FC310 is implicit; once the configuration
image is changed by any user of services (Serial/Ethernet/
Etc.,) the FC310 becomes RESERVED. Performing a
SaveConfiguration, RestoreConfiguration or FcRestart
RELEASES the FC310 so that other devices may access it.
When the FC310 services interface is reserved, set commands
are unavailable, but get commands are available. Note that at
least one service interface always has access to the FC310 at all
times. This interface always reports a RELEASED status, since
it may issue set commands.
VerboseMode
Sets the Command Line Interface to display extended
information about a parameter when the help command is
given. When verbose mode is enabled, parameter values are
generally preceded by labels in responses to the get commands.
Only the parameter value is output when verbose mode is
disabled.
