Introduction 0
This document describes the configuration and operation of the FC420
Fibre Channel Bridge option installed in the M2500 library.
For FC420 installation steps, refer to the FC420 Fibre Channel Bridge
Quick Reference Guide (PN T6473054).
For a description of M-Series library operating procedures, see the
Tandberg Data M-Series Library User’s Guide (PN T6423045).
Fibre Channel
Overview
The M2500 library is controlled by a host computer via a SCSI
0
differential bus using the SCSI-2 medium changer command set. The
library’s architecture allows for easy conversion from the SCSI host
interface to a Fibre Channel host interface by installing the FC420
Bridge option.
Fibre Channel is a serial data transfer architecture for use with
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 of up to 500 meters
• Up to 2 GB/sec data transfer rates with Autonegotiate
• 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
Library Operation
After FC420 Bridge
Installation
0
• 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.
Once the FC420 Bridge SCSI to Fibre Channel option is installed and
tested, the library operates exactly as a library with a SCSI host
interface. User operation of the library via the graphical user interface
(GUI) panel is unchanged.

Cabling the M2500 Library for Fibre Channel 0
The cabling configuration used for the M2500 library with the FC420
option depends on the following factors:
• Number of tape drives installed
•Tape drive type (SDLT or LTO)
• Number of FC420 Fibre bridges installed
• Data transfer rate of the storage area network (SAN)

If the M2500 library has only one or two tape drives, the cabling is the
0
same regardless of drive type or SAN. One- or two-drive libraries only
require one FC420 Fibre bridge.

As shown in the figure, a SCSI daisy chain is established from one of
the SCSI ports on the FC420 to the SCSI controller and then to drive 0,
where the daisy chain is terminated. The SCSI controller is included in
the chain to pass SCSI commands to the robot.
The SCSI controller and drive 1 must be on the same SCSI bus because
the SCSI controller has termination disabled.

In a two-drive library, the second drive (Drive 2) should be connected
to the available FC420 SCSI port, creating a second SCSI bus. This fully
utilizes the FC420 Fibre bridge and maximizes the communication
bandwidth available to each tape drive.
When cabling M2500 libraries with three or more tape drives, you
0
need to know the type of tape drive installed in the library and the
data transfer rate of the SAN to determine the correct SCSI
configuration.
Note: As with the one- and two-drive configurations, all Fibre-to-
SCSI cabling configurations must include the SCSI controller
so that SCSI commands intended for the robot are
successfully communicated.

SDLT/LTO Drive Cabling with a 1-GB SAN 0
For example, if you have SDLT or LTO drives and a 1 GB SAN,
Quantum recommends a ratio of one tape drive per FC420 SCSI port.
This means that three- and four-drive libraries would require a second
FC420 Fibre bridge, and five- and six-drive libraries would require
three FC420 bridges, as shown in Figure 3
Note: SDLT and LTO tape drives are sometimes referred to as
Superdrives.

SDLT/LTO Drive Cabling with a 2-GB SAN 0
If the M2500 library with SDLT or LTO drives is connected to a 2-GB
SAN, Tandberg Data recommends a maximum ratio of 2 tape drives
per FC420 SCSI port. This means that one FC420 Fibre bridge could
manage up to four tape drives, but a second FC420 Fibre bridge would
be required for libraries with five or six tape drives.

Configuring FC420 Firmware 0
Each FC420 Fibre bridge installed in the M2500 library must be
configured using the FC420 Bridge Services software. The key to
successfully configuring the FC420 Fibre bridge is to:
• Know exactly how the SCSI cabling in the library is configured
including:
• How many FC420 Fibre bridges are present in the library.
• How many SCSI buses are present in the library.
• How many SCSI devices are connected to each bus.
This was established in the previous section of this document.
• Use the FC420 Bridge Services software to create a Map file
identifying which SCSI devices are electrically connected to which
Fibre Channel ports on the FC420 board.
Setting Up an Ethernet
Connection
The major steps for configuring FC420 Fibre bridge firmware involve:
• Setting Up an Ethernet Connection
• Verifying Current FC420 Firmware on page 10
• Setting Local Echo Mode
• Scanning the SCSI buses on the Library
• Creating a Map File for the FC420

FC420 Services Software Commands 0
The FC420 Services Software is resident on each FC420 Bridge board,
and is used to configure the bridge for use in the 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.
FC420 Service
Software Operation
The Command Line Interface provides access to the FC420 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.

Command Description Default Syntax
November 2002
Reserve (Immediate)
Reservation of the FC420 is implicit; once the configuration
image is changed by any user of services (Serial/Ethernet/Etc.,)
the FC420 becomes RESERVED. Performing a
SaveConfiguration, RestoreConfiguration or FcRestart
RELEASES the FC420 so that other devices may access it.
When the FC420 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 FC420 at all times.
This interface always reports a RELEASED status, since it may
issue set commands.
RestoreConfiguration
(Immediate)
Restore to factory default
configuration or the last saved
configuration. The new configuration
must be saved to take effect.
RouteChange
(Immediate)
Map a Fibre Channel port (fp) and
LUN (fl) to a SCSI bus (sb), target (st),
and LUN (sl). Valid route change
entries are:
fp (0-2)
fl (0-31)
