1 Fibre Channel is a key technology for storage

Fibre Channel is a serial communications technology designed to transfer large amounts of data between a variety of hardware systems over long distances. It is a key technology for applications that require shared, high bandwidth access to storage.

Fibre Channel provides a logical point-to-point serial channel for the transfer of data between a buffer at a source device and a buffer at a destination device. It moves buffer contents from one port to another, without regard to the format or meaning of the data, so different upper level protocols are able to run over Fibre Channel hardware.

The Fibre Channel architecture is structured as a hierarchical set of protocol layers. Defined within these layers are rules for signal interfaces, serial encoding and decoding, error control, frame format and communications protocols.

All ATTO FibreBridge

models can be used in a

SAN (Storage Area Network) to connect a variety

A SAN is a shared storage architecture connecting computers and storage devices for online data access. Each connected system can directly access any attached storage device. Storage devices could include RAID, tape backup, tape library, CD-ROM library, standalone disk drives or JBOD.

SANs maintain greater fault tolerance and load balancing by supporting server clustering and failover (the ability for one server to take over for another in the event of a failure).

ATTO FibreBridge models provide the interface between SCSI and Fibre Channel resources in SANs. Possible configurations depend upon your

current hardware and what you need to do. of Fibre Channel and SCSI devices to meet your needs.

2.3 Connecting SCSI devices to SCSI ports

ATTO FibreBridge SCSI ports are used to connect SCSI storage devices into the Fibre Channel Storage Area Network (SAN).

A FibreBridge may have the following types of SCSI ports:

Ultra 2 (LVD) SCSI

Single Ended Ultra SCSI

High Voltage Differential (HVD) Ultra SCSI

80 MB/sec. max per bus

40 MB/sec. max per bus

MB/sec. max per bus

The high voltage differential (HVD) FibreBridge is compatible only with HVD SCSI devices. An LVD FibreBridge is downward compatible with Single Ended Ultra SCSI as well as Fast, Wide, or Narrow SCSI devices.

Each SCSI port is totally independent from the any other SCSI port. This means that each bus is capable of supporting 15 devices and each bus is capable of 40 or 80 MB/sec. (Ultra or Ultra2).

However, you may use externally provided software striping to create a RAID 0 group that includes devices from all SCSI busses to increase overall performance.

Another advantage of independent SCSI ports is that each SCSI bus auto-negotiates the appropriate sync rates with the connected devices. If slower devices are mixed with faster Ultra2 devices, the bus will communicate at the rate of the slowest device, thus wasting the performance capabilities of the faster devices. You should connect slower devices to one SCSI port and connect faster devices on another port on your FibreBridge.

To connect SCSI devices to the ATTO FibreBridge:

1Connect a VHDCI SCSI connector from the

SCSI device to a port on the FibreBridge

4500.

Check the type of cable and cable length limit for each port. It is important to keep cable lengths as short as possible to ensure the highest signal quality and performance. These cable lengths include the wiring inside the devices.

Device type Cable limit

Ultra SCSI Single Ended (SE) 1.5 meters

Ultra SCSI High Voltage Differential (HVD) 25 meters

Ultra2 SCSI Low Voltage Differential (LVD) 12 meters

2 Set the IDs of the SCSI devices connected to

the bridge to a value other than 7. You should use a sequential ID starting at 0 for each device. Each SCSI port in the ATTO FibreBridge has an internal factory setting ID of 7, typical for a SCSI initiator device.

NOTE

The entire SCSI bus will operate at the speed of the slowest device. If you wish to mix devices of different SCSI speeds on the bridge, it is best to place them on separate busses. That is, put the slower devices on bridge SCSI busses 0 and 1, and the faster devices on bridge SCSI busses 2 and 3. Each bus is independent so each can operate at different speeds.

3 Terminate each SCSI bus after the last

device. The bridge is terminated internally.

The FibreBridge supports a wide variety of SCSI storage devices including stand-alone drives, removable drives, JBODs, RAIDs, tape, CD and DVD drives, changers, libraries and magneto optical drives.

Page 17

2.4 Connecting the Fibre Channel ports

The Fibre Channel ports on the ATTO FibreBridge 4500C/R/D connect the bridge into either a Fabric or Arbitrated Loop.

Fibre Channel technology offers a variety of cabling options including standard copper, equalized copper, multimode fiber optic, and single mode fiber optic.

The FibreBridge 4500C/R/D uses an SC fiber optic cable connector.

Cable length Cable type Cable size Connector

Up to 175 meters multi mode fiber optic 62.5 micron SC optic connector

Up to 500 meters multi mode fiber optic 50 micron SC optic connector

The type of cable to use varies depending upon the application, environment and distance. The following tables illustrate the different cable options available.

Make sure all cables are anchored securely at both ends with the proper connectors.

3 Configuring the FibreBridge

Configuration of the ATTO FibreBridge, also known as FibreBridge Services, is available via ATTO BridgeTools (a graphical user interface configuration manager), Command Line Interface (CLI) or a menu.

FibreBridge Services includes displaying and modifying various attributes of FibreBridge operation, as well as the update of firmware. You may use a graphical interface (ATTO BridgeTools), command line interface (CLI) or

Company ID Device ID

The Institute of Electrical and Electronics Engineers (IEEE) assigns each manufacturer a unique Company ID. The Device ID field contains a unique value assigned by ATTO Technology to every Fibre Channel product produced by ATTO Technology.

Arbitrated Loop Port Address (AL_PA)

On a Fibre Channel Arbitrated Loop, the FibreBridge appears at a single Arbitrated Loop Port Address (AL_PA). Each device on an arbitrated loop is assigned a unique AL_PA during loop initialization. The FibreBridge supports both modes of AL_PA assignment, commonly referred to as

hard

and

soft addressing

Soft addressing allows the loop initialization master to assign the FibreBridge a unique AL_PA during the loop initialization process. The AL_PA assigned cannot be determined before loop initialization. For example, adding new devices to an arbitrated loop may change the AL_PA assigned to the FibreBridge.

Hard addressing allows a predetermined AL_PA to be assigned to the FibreBridge. The FibreBridge will try to acquire the desired hard AL_PA. If another device has already been assigned the specified AL_PA, the FibreBridge will acquire a currently unassigned AL_PA.

ATTO BridgeTools software allows you to select either hard or soft addressing modes. The default mode is soft addressing.

Addressing devices

SCSI devices connected to the FibreBridge also show up as Fibre Channel LUNs to the host computer. SCSI devices must be on the same addressing level as the SCSI portion of the FibreBridge. The FibreBridge SCSI ports must be set to different SCSI IDs than the devices on the bus.

3.1.1 Mapping devices

Access to SCSI devices is via Fibre Port and Fibre LUN addresses mapped to SCSI bus, target and LUN. CLI commands are used to modify the mapping.

➔

The Command Line Interface commands

AutoMap, AddressMap

and

RouteXxxxx

map Fibre Channel ports and LUNs to SCSI bus/target/LUNs. Host applications use the Fibre port and Fibre LUN to access specific SCSI devices.

For information on how to access the CLI via a text interface or ATTO BridgeTools, a graphical interface, see Chapter 4 and Chapter 3.1.

AutoMap

AutoMap establishes the default map of Fibre ports and Fibre LUNs by distributing the devices over the Fibre ports you designate. To distribute all devices to across all the Fibre Channel ports, type

Automap

To assign a devices to specific ports, type in the port numbers you wish to use

Automap [0 | 1 | 2 ]

AddressMap A

AddressMap A enables mapping of any SCSI or internal device to a specific Fibre Channel port and LUN. Internal devices and external SCSI devices are presented as LUNs to a Fibre Channel host using route mapping. Each Fibre Channel port has its own Fibre Channel node name and port name. Type

AddressMap A

AddressMap B

AddressMap B enables port failover, the automatic substitution of the mapping from a failed port to a port reserved to take over for it. Internal devices and external SCSI devices are presented as LUNs to the Fibre Channel host using route mapping. Each Fibre Channel port has its own Fibre Channel node name and port name. The command configures the FibreBridge to either

set AddressMap B 1

set AddressMap B 2

To return an active port back to its pre-failover state, type

FcPortFailure recover

AddressMap C

AddressMap C uses static device addressing rather than route mapping to present internal devices and external SCSI devices as Fibre Channel LUNs to a host. All ports on the FibreBridge use the same Fibre Channel node name, but each port has a unique Fibre Channel port name.

The FibreBridge appears as a single Fibre Channel device with three ports to a host. All devices are available on each Fibre Channel port at the same LUN as follows:

All Fibre Channel ports will report a particular device (both internal and SCSI) at the same LUN. The LUNs reported to a host in response to a

ReportLUNs

map all devices to one port, leaving one port offline and one port reserved to take over in case the active port fails:

RouteXXX family

If you have not enabled AddressMap C, you may use CLI commands to find all the SCSI devices on SCSI busses. With this information you then decide where you want to place these devices on the Fibre Channel ports.

You can then manually map the devices using the RouteXXX family of commands or the command (see Chapter 4.1.8) available through the Command Line Interface or the menu or by using ATTO BridgeTools (see Chapter 4 and Chapter 3.1).

RouteDisplay

displays the current mapping, if AddressMap C has not been enabled, in Fibre port, Fibre LUN order, showing the mapped SCSI bus/target/LUN, and the current status of the device (online, offline, disabled, mapped, unmapped). RouteDisplay may be used at any time.

RouteOffline, RouteChange, and RouteOnline

modify the mapping as required to make a device inaccessible, to replace a non-functioning mapped unit with another or to manage wear on tape drives. The commands will not modify a port being used as a failover port in AddressMap B mode.

In the chart at right, the SCSI device on SCSI bus 0 at SCSI address of ID 0 LUN 0 is being mapped to Fibre Port 0 (on the FibreBridge) at Fibre Channel LUN 4.

AutoMap

SCSI device is mapped to two different Fibre Port and/or Fibre Channel LUNs, these Fibre Port and Fibre Channel LUNs will be taken offline automatically until the conflict is resolved.

The BootScan command

(see Chapter 4.1.8), available through the Command Line Interface, ATTO BridgeTools or the menu (see Chapter 3.1 and Chapter 4), provides dynamic mapping of SCSI devices to Fibre port/LUN combinations via a SCSI bus scan at boot time. Each time the FibreBridge is reset or power-cycled and BootScan is enabled, a bus scan will occur on all SCSI busses. All devices discovered during the bus scans will be assigned to a Fibre port, Fibre LUN combination until the next reset/power cycle. The dynamic mapping will replace the current mapping of the FibreBridge.

Note: two SCSI devices cannot be mapped to the same Fibre Port and Fibre Channel LUN. Also, if the same

3.2 Handling multiple initiators

Several Fibre Channel hosts or initiators may initiate commands through the FibreBridge to SCSI devices. The basic mechanism to resolve possible conflicts among initiators is to use SCSI

Reserve

and

Release

commands.

A Fibre Channel host may need exclusive access to a SCSI device. SCSI

Reserve

and

Release

commands allow logical units to be reserved or released under host control.

The FibreBridge intercepts any Reserve or Release command from a Fibre Channel host, performs initial processing and, if appropriate, relays the Reserve command to the SCSI device.

In a FibreBridge environment, the identity of the initiator (WWN) is not relayed to the SCSI device. A two-step process addresses initiator identity in the FibreBridge, and reserves the SCSI device on behalf of the FibreBridge.

Initiators on both the Fibre Channel (via the FibreBridge) and on the SCSI bus may initiate reserve and release commands to the SCSI devices.

The FibreBridge processing of reserve and release commands involves two tiers of verification. The first tier is within the FibreBridge; the second tier is within the SCSI device.

1 The FibreBridge receives a SCSI Reserve

command.

Tier 1

2 The FibreBridge determines, via its

internal database, whether there are conflicting concurrent reservations from Fibre Channel hosts for the target SCSI device.

3 If there is a conflict, the FibreBridge

returns a check condition with reservation conflict to the initiator.

4 If there is no conflict, the FibreBridge

marks the SCSI device as reserved in its internal database.

Tier 2

5 The FibreBridge relays the Reserve

command to the SCSI device.

6 The SCSI device determines whether it is

already reserved.

7 If the SCSI device is already reserved, it

returns a reservation conflict to the FibreBridge. The FibreBridge removes its reserved indicator in its internal database, and returns reservation conflict to the initiator.

8 If the SCSI device was not previously

reserved, the SCSI device is reserved and returns success to the FibreBridge. The FibreBridge then returns success to the initiator.

The FibreBridge does not implement extent reservation.

Single initiator

A single initiator presents no conflicts.

1 A single Fibre Channel initiator sends

the Reserve command through the SAN to the FibreBridge

2 The FibreBridge determines that no

reservation conflict exists at Tier 1.

3 The FibreBridge sends the Reserve

command to the SCSI target.

4 The SCSI target is reserved until a

Release command is sent by the Fibre Channel initiator.

Multiple Fibre Channel initiators

Multiple Fibre Channel initiators share a Fibre Channel connection on the SAN with a Fibre Bridge, and there are no other initiators on the SCSI bus.

7 The FibreBridge determines the SCSI

device is already reserved.

Access the ATTO FibreBridge through in-band SCSI over Fibre Channel

One way to access the ATTO FibreBridge through in-band SCSI over Fibre Channel is to use ATTO BridgeTools, a Java-based graphical interface configuration utility, to flash firmware and manage configuration for many FibreBridge models. The ATTO BridgeTools program currently supports Sun Solaris™ 8, MAC® OS

10.1 and Windows

95/98/ME, NT and 2000.

Refer to the ATTO BridgeTools Installation and Operation Manual for complete instructions to how to install and operate the program.

In-band SCSI commands (Write Buffer and Read Buffer) may be issued to the FibreBridge to manage configuration via two mechanisms:

program uses a SCSI CDB (command descriptor block) to select the buffer ID of the configuration parameters to be affected, and the new value of the parameter. Most FibreBridge configuration options are available.

Access the ATTO FibreBridge over the RS-232 port

The ATTO FibreBridge supports remote service operations over the RS-232 serial port using standard terminal emulation software available with most systems.

1 Connect a DB-9 crossover serial cable (null

modem) between the ATTO FibreBridge serial port and one of the computer’s serial COM ports. A gender changer or DB-9 to DB-25 converter may be needed depending on the cables being used.

To save the configuration:

To access the ATTO FibreBridge via Ethernet:

1 Connect an Ethernet cable between the

FibreBridge and a 10/100Base T connection. You may need a crossover cable connecting directly to a computer. The ATTO FibreBridge will auto detect the Ethernet speed if configured to do so.

2 Access using any standard Telnet program.

To connect via Telnet:

1 Supply the IP address to the Telnet program.

The local echo should be set to on if the Telnet software supports it. Use Vt100 for communication.

2 Verify that the bridge can be accessed on

the local Ethernet by using the Ping utility. On most systems, type ping <IP Address>. If

the FibreBridge does not respond, it may not be connected correctly to the network, or is somehow unreachable by the computer from which it is being pinged. Check network connections and security as well as the ATTO FibreBridge.

To set up and configure FTP:

1 Ensure that the FTP program is in binary

mode. Access the ATTO FibreBridge at the IP address that was previously set (or the default).

2 Log into the ATTO FibreBridge. The

username the bridge will accept is sysadmin. Enter userid as the password.

4.1.8 Mapping commands

Access to SCSI devices is via Fibre Port and Fibre LUN addresses mapped to SCSI bus, target and LUNs. CLI commands are used to modify the mapping.

The AddressMap, AutoMap and RouteXxxxx map Fibre Channel Port/LUN to SCSI bus/target/LUN. Host applications use the Fibre Port and Fibre LUN to access specific SCSI

devices and set up port failover. See Chapter 3.1 and Chapter 3.1.1 for more information.

Appendix B shows the sequence of AutoMap and RouteXxxxx commands.

4.2 FibreBridge menu text-based CLI interface

Configuration of many models of the ATTO FibreBridge is available via a menu which contains most commands available through CLI but in a hierarchical user-friendly format. It follows a standard menu/choice model.

Configuration of the FibreBridge includes displaying and modifying various attributes of FibreBridge operation, as well as the update of firmware. For many FibreBridge models (see Chapter 2), the menu system provides access to ATTO FibreBridge services in a standard menu/choice model, and displays options and current status.

Accessing the menu

1 Communicate with the FibreBridge through the

RS-232 port or Telnet over Ethernet.

2 The Command Line Interface mode is available

after the initial display is complete, ending with the word Ready.

3 Type Menu to enter the menu system.

Conventions

Ellipses

(...) show that a choice will lead to another menu. For example, if you choose a) on the FibreBridge Main Menu, you will see another menu, FibreBridge Configuration Menu. If you choose b) Fibre Channel Configuration, you will see a different menu, Fibre Channel Configuration Menu (see examples at right).

Brackets

after a menu item show current settings. If you choose a) on the FibreBridge Configuration Menu (one level beyond the Main Menu) (see examples at right) you will see

FibreBridge Name [ ].

No ellipses follow

: this is the last choice. If you wish to change the [ ], you type in your response to

Enter FibreBridge Name (Max of 8 characters)

In the FibreChannel Configuration Menu, choosing Port Connection Mode (loop) presents you with the following:

This option determines the port type to which the FibreBridge will attempt to login. Loop Mode allows Arbitrated Loop (FC_AL) logins via an FL_Port. Point-to-Point Mode (ptp) allows connection to a fabric port (F_Port). Type the letter of your choice and press ‘Enter’. Connection Mode: a) Loop, b) Point-to-Point:”

Typing “a” will enable loop mode, typing “b” will enable point-to-point mode.

4.3 ATTO BridgeTools provides graphical interface

The simplest way to communicate with the ATTO FibreBridge is to use ATTO BridgeTools, a Java-based graphical interface configuration utility designed to flash firmware and manage the configuration for all models of the FibreBridge.

Configuration of the FibreBridge includes displaying and modifying various attributes of FibreBridge operation, as well as the update of firmware. BridgeTools detects which FibreBridge model is available and presents you with the applicable configuration options.

The ATTO BridgeTools program currently supports Sun Solaris 8, MAC OS 10.1 and Windows 95/98/ME, NT and 2000.

Communicate with the FibreBridge either through in-band SCSI over Fibre Channel, the RS-232 port or Telnet or FTP over Ethernet.

Select in-band connection direct over the Fibre Channel link, RS-232 port or Ethernet port.

The ATTO BridgeTools Manual has complete instructions on how to install and operate the program.

Page 48

4.4 In-band CLI uses SCSI over Fibre port

In-band Command Line Interface (CLI) configures and manages the ATTO FibreBridge using SCSIbased CLI commands over a Fibre port connection.

In-band CLI allows a programmer to configure the FibreBridge while it is moving data. Using a programmer’s interface, ATTO FibreBridge Services CLI commands as described previously in this manual may be implemented. The only command not available is

menu.

In-band CLI is implemented as a device separate from the FibreBridge itself. It uses a different LUN than the FibreBridge, and reports as a Storage Enclosure Services (SES) device (device type 0x0D). This LUN is referred to as the ServicesLUN

The ServicesLUN is visible on all Fibre ports but is actually a single unit. The default value for each Fibre port’s ServicesLUN is 0x08.

The ServicesLUN must be reserved for each Write Buffer/Read Buffer pair, using the SCSI Reserve command to insure integrity of the inband CLI session.

1 An initiator (host) sends a SCSI Reserve

command to the ServicesLUN.

➔

If the ServicesLUN is not reserved by another initiator, the ServicesLUN is now reserved and ready to begin a new CLI session.

➔

If the FibreBridge configuration is reserved by a different CLI session (i.e. serial or Telnet), the in-band session will not be allowed to modify the FibreBridge configuration. If you try, the results buffer of the ServicesLUN will return:

Process X has the configuration reserved. ID of this session = Y Ready.

2 The initiator issues a SCSI Write Buffer

command to the ServicesLUN. A Write Buffer command must be accompanied by an ASCII buffer representing the CLI command string such as

set FibreBridgeName FB4500

3 The ServicesLUN will execute the command

line and create feedback in the form of ASCII characters into a buffer. This buffer is 8 KB and circular. Retrieve the results by issuing a Read Buffer command before issuing another Write Buffer command.

4 A subsequent Write Buffer command will

execute the new command line and overwrite the previous results in the buffer with new results.

5 The ServicesLUN can be released by

issuing a SCSI Release command to the Services LUN after each Write/Read Buffer pair, or multiple Write/Read Buffer pairs.

Initiator (Host) FibreBridge

Reserve ServicesLUN return: “ok”

Write Buffer ServicesLUN bid 0 “get Temperature”

Read Buffer ServicesLUN bid 0

Release ServicesLUN return: “ok”

executes the CLI command, stores output in buffer

return: ”Temperature=28C\r\n\Ready.\r\n \0”

I/O details

The buffer sent to the Services LUN during the data out phase of a Write Buffer command must be:

➔

ASCII data

➔

maximum 80 bytes length

➔

terminated with either a carriage return character (0x0D), line feed character (0x0A) or NULL character (0x00)

➔

Characters following the first carriage return character, line feed character or NULL character are ignored.

ATTO Technology FibreBridge 4500 Installation and Operation Manual

Page 49

The buffer retrieved from the Services LUN during the data-in phase of a Read Buffer command will be:

➔

ASCII data

➔

8 KBytes (8192 bytes) in length

➔

terminated with a NULL character (0x00)

➔

Characters following the NULL character are meaningless.

A CHECK_CONDITION, INVALID_PARAMETER

_IN_CDB will be returned to an initiator that specifies an incorrect Buffer ID, Mode, Length or Buffer Offset. The Mode is always Data (0x2), the Buffer ID is always 0 and the Buffer Offset is always 0.

5 Enhancing performance

SpeedWrite is a method to improve the performance of WRITE commands to SCSI devices attached to the FibreBridge 4500 enabled by CLI commands.

SpeedWrite is a method to improve the performance of FCP WRITE commands to SCSI devices attached to the FibreBridge. Using the CLI command SpeedWrite, you can specify the SCSI bus, target and LUN of a mapped device or specify [all] to set or get the state of all currently mapped SCSI devices.

SpeedWriteDefault specifies the state of SpeedWrite for any SCSI devices mapped manually or via an AutoMap operation. If enabled, any new SCSI device will use SpeedWrite performance enhancement by default.

7 Serverless backup support

Serverless Backup is an application that allows data to be copied between two storage devices (Fibre Channel disks, SCSI disks and SCSI tapes) with minimal intervention from a server.

As the volume of data on a network grows, the resources required to back up this data also grow. Data protection requires that large volumes of data be copied from on-line storage devices to dedicated archive devices. This places a very heavy load on the host processors, I/O busses, memory busses, and frontend network, thus reducing the servers ability to “serve” its clients, as well as a general reduction in performance.

Serverless Backup uses the Extended Copy command compliant with T10/99-143rl to allow a “copy manager” (the FibreBridge) to execute all of the read and write operations necessary to move data. Blocks of data are moved directly from the Fibre Channel storage through the bridge to SCSI tape or from SCSI storage through the bridge to the SCSI tape, all at Fibre Channel and SCSI speeds (as compared to moving data across the Ethernet network).



The ATTO FibreBridge

will execute Extended Copy commands to and from SCSI tape drives connected directly to the FibreBridge. The hard drives you are backing up or restoring to can be anywhere on the Storage Area Network, including SCSI drives attached to the bridge. The Extended Copy command contains target and segment descriptors used to define which data is to be moved between which devices.

Target Descriptors allow the host to describe the devices involved in the Extended Copy. To be compatible with all copy agent application packages, the FibreBridge implementation supports World Wide Name, N_Port ID, and WWN plus N_Port ID descriptor types.

Segment Descriptors describe the data to copy and how much of it to copy. The two most common types of Segment Descriptors are “block (disk) to stream (tape)” and “stream (tape) to block (drive)”. The FibreBridge also supports “block to block,” “inline to stream,” and “stream to discard.”.

The FibreBridge will support copying up to 830 MB of data in a single Extended Copy command. Larger files must be backed up or restored using additional operations. The bridge can support up to eight simultaneous Extended Copy commands.

Please check the ATTO Technology, Inc. web site at

www.attotech.com

for a complete list of all of the applications supported as well as detailed installation and configuration tips.

How serverless backup works

1 A copy agent on the server provides a user

interface to begin a backup or restore operation as well as manage and synchronize the movement of data sets. This copy agent is either included or available as an add-on with many high-end tape backup software applications on the market.

2 The server sends a single Extended Copy

command to the FibreBridge or to a SCSI device beyond the bridge.

3 The bridge interprets the segment descriptors

and issues read commands to the appropriate devices.

4 Once enough data is read, the bridge will issue

write commands to the appropriate device.

5 Once all of the segment descriptors have been

executed, the bridge will send status to the copy agent running in the server. The data never passes through the server, thus freeing the CPU and Memory to process other requests.

To enable serverless backup:

1 Access the FibreBridge either through RS-232 or

Ethernet.

2 After the Ready prompt, type set Fcinitiator

enabled.

3 At the next Ready prompt, type saveconfiguration

restart.

4 The FibreBridge is now ready to perform

serverless backup.

ATTO Technology FibreBridge 4500 Installation and Operation Manual

Page 53

To monitor the progress of serverless backup operations,

1 Access the FibreBridge through RS-232 or

Ethernet.

2 Type get XCStatus to determine the status of

Extended Copy commands. The return will present the CmdNumber field, a unique identifier for a particular Extended Copy command.

Exhibit 7-1 Once the server sends a command to the FibreBridge for extended copy, the FibreBridge manages the backup procedure, by-passing the server.
