Fibre Channel Overview

The 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

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)

If 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.

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.

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.

Terminator

SAN

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.

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.

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.

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

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.

• Setting up an Ethernet Connection

• Verifying Current FC420 Firmware

• Scanning the SCSI Busses on the Library

• Creating a Map File for the FC420

Note: These major steps must be repeated for each FC420 bridge in the

library.

To set up an Ethernet connection between the FC420 bridge and a service PC

or other stand-alone computer equipped with Windows or Windows NT:

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

The 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 is sent.

SaveConfiguration command

• 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 modified parameters take effect. When such a command is executed an asterisk appears next to the command line prompt.

Command Syntax 0 The following is a list of syntax used to describe command lines:

• [ ] indicates required entry

• < > indicates optional entry

• | indicates choose one entry

FcWWName

FibreBridgeModel

FibreBridgeName

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.

ServicesLUN

SpeedWrite

Identifies the LUNs (one per Fibre port) to be used during an in-band command line interface (CLI) session with a given host. This information is taken from NVRAM.

Any map coinciding with a userspecified ServicesLUN must first be set to offline before attempting to change the ServicesLUN. This map will be destroyed upon power-cycling the FC420 bridge. Disabling a ServicesLUN for a particular Fibre port will destroy the map to the FC420 bridge for that port.

Enables/disables SpeedWrite functionality to any SCSI device currently mapped to the FC420 bridge. To enable/disable SpeedWrite for a particular device, specify the SCSI bus (sb), the target (st), and the LUN (sl). Specify “all” to enable/disable this option for all currently mapped SCSI devices.
