4 Cabling the Library for Fibre Channel
Fibre Channel
Overview 0The Quantum ATL M-Series libraries are controlled by a host computer via an LVD SCSI differential bus using the SCSI-2 medium changer command set.
The library’s Prism 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-to-storage applications.
Fibre Channel advantages include:
• Connection distances of up to 10 Kilometers
• Up to 2 Gb/sec data transfer rates with Auto-negotiate
• 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 storage area network (SAN), which can increase the total
throughput of all devices on the SAN
Library Operation after
Prism FC420 Bridge
Installation 0
Once the Prism 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 Library for Fibre Channel 0
The cabling configuration used for the ATL M-Series library with the FC420
bridge option depends on the following factors:
• Number of tape drives installed
• Tape drive type (DLT8000, SDLT 220, SDLT 320, SDLT 600, HP LTO Gen
1, or HP LTO Gen 2)
• Number of FC420 bridges installed
• Data transfer rate of the storage area network (SAN)

Cabling the Library for Fibre Channel 5
One- and Two-Drive
Library Cabling 0If you are cabling an ATL M1500 library, or an ATL M2500 library with only one or two tape drives, the cabling is the same regardless of drive type or
SAN. One- or two-drive libraries require only one FC420 bridge.
Figure 2 shows the cabling for a one-drive library.
Figure 2 One-Drive Library
Cabling
In a one-drive configuration (as shown in figure 2), a SCSI daisy chain is
established from one of the SCSI ports on the FC420 bridge to the SCSI
controller and then to drive 1, 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.
Note: HP LTO Gen 2 and SDLT 600 require 2 GB SAN connections. All
other drive types may have either a 1 GB or 2 GB SAN connection.

6 Cabling the Library for Fibre Channel
Figure 3 shows typical cabling for a two-drive library.
Figure 3 Two-Drive Library
Cabling
In a two-drive library, the second drive (drive 2) should be connected to the
available FC420 port, creating a second SCSI bus. This utilizes the FC420
bridge fully and maximizes the communication bandwidth available to each
tape drive.
Cabling an ATL M2500
with Three or More
Drives 0
When cabling an ATL M2500 with three or more tape drives, you 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.
To cable a library with:
• SDLT 220, SDLT 320, or HP LTO Gen 1 drives, refer to SDLT 220, SDLT
320, or HP LTO Gen 1 Drive Cabling with a 1 Gb SAN or SDLT 220, SDLT
320, or HP LTO Gen 1 Drive Cabling with a 2 Gb SAN
• SDLT 600 or HP LTO Gen 2 drives, see SDLT 600 or HP LTO Gen 2 Drive
Cabling
• DLT8000 drives, see DLT8000 Drive Cabling
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 communicated
successfully.

SDLT 220, SDLT 320, or HP LTO Gen 1 Drive Cabling with a 1 Gb SAN 0
If an ATL M2500 containing SDLT 220, SDLT 320, or HP LTO Gen 1 drives is
connected to a 1 Gb SAN, a ratio of one tape drive per FC420 SCSI port is
recommended. This means that three- and four-drive libraries require a
second FC420 bridge, and five- and six-drive libraries require three FC420
bridges, as shown in figure 4.
Figure 4 One-Drive-Per-
FC420-Port Cabling
SDLT 220, SDLT 320, or HP LTO Gen 1 Drive Cabling with a 2 Gb SAN 0
If an ATL M2500 containing SDLT 220, SDLT 320, or HP LTO Gen 1 drives is
connected to a 2 Gb SAN, a maximum ratio of two tape drives per FC420 SCSI
port is recommended. This means that one FC420 bridge could manage up to
four tape drives, but a second FC420 bridge is required for libraries with five
or six tape drives.
Note: SDLT and LTO tape drives are sometimes referred to as
Superdrives.

Configuring FC420 Firmware 11
Configuring FC420 Firmware 0
Each FC420 bridge installed must be configured using the FC420 Bridge
Services software. To configure the FC420 bridge successfully, it is important
to:
• Know exactly how the SCSI cabling in the library is configured,
including:
• How many FC420 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 connected to which Fibre Channel ports on the
FC420 board
The major steps for manually configuring FC420 bridge firmware are:
•Setting up an Ethernet Connection
•Verifying Current FC420 Firmware
•Scanning the SCSI Busses on the Library
•Creating a Map File for the FC420
Setting up an Ethernet
Connection 0To set up an Ethernet connection between the FC420 bridge and a service PC or other stand-alone computer equipped with Windows or Windows NT:
1Connect a Field Service Notebook to the FC420.
aTurn on the Field Service Notebook.
bDisconnect the Ethernet cable to the FC420 bridge.
Note: If you have an MC300 PMC, refer to the MC300 Prism Management
Card User’s Guide, PN 6473040, to configure your FC420 bridge (or
bridges), instead of the following steps.
Note: These major steps must be repeated for each FC420 bridge in the
library.
Note: The FC420 bridge has DHCP enabled, which searches for a server
to get an address. The DHCP server for this application is the
MC300 PMC, which is the default. If you have an MC300 PMC, do
not perform this procedure, refer to the MC300 Prism Management
Card User’s Guide, PN 6311631, for FC420 bridge administration.

Prism FC420 Services Software Commands 0
The Prism FC420 Services Software is resident on each FC420 bridge, and is
used to configure the bridge for use in the library. The software uses a
Command Line Interface (CLI).
Prism FC420 Service
Software Operation 0The Command Line Interface provides access to the FC420 services 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 Syntax 0The following is a list of syntax used to describe command lines:
• [ ] indicates required entry
• < > indicates optional entry
• | indicates choose one entry

20 Prism FC420 Services Software Commands
FcWWName Sets/displays the current World Wide
Name (WWN) of the Fibre Channel
interface referenced. Each Fibre port has
a unique WWN. The least significant 6
bits of the WWN are used as the
Ethernet MAC address.
The set variant of the command allows
the user to change the last three bytes of
each WWN. Please note, however, that
the most significant bit of the three bytes
must be 1 in order to provide WWN
verification. Also note that the last bit of
each WWN may only be assigned one of
the following values: 0, 4, 8, or C for port
0; 1, 5, 9, or D for port 1; and 2, 6, A, or E
for port 2.
Fabric and loop operation is
unpredictable if duplicate WWNs are
used.
