About Serverless Backup
Recent advances in data protection architectures have added the ability to back up data by
moving it directly from disk to tape without first passing through a backup server. This is
called serverless backup, and it utilizes a new SCSI command, Extended Copy (EC). A
host is involved in executing the EC command, though it is typically not the server. The
Chaparral family of Intelligent Storage Routers is enabled to execute the EC command
under the control of most major backup applications.
The EC command consists of three primary pieces of information:
I
I
I
Source addresses
Destination address
In-line data
The source addresses tell the router where the data that is being copied is physically
stored, on what device and at what physical locations. This information is provided by a
backup application, which must translate file information into the physical storage
locations. The application sends this list of addresses in the order it is to be written to the
destination device, often a tape drive in a backup scenario.
For the destination address, the EC command assumes that any tape device that is being
copied to is in the proper location, so all the router needs to know is its target address,
typically a LUN on the SAN. The in-line data is used to allow applications to maintain a
specific format, and can be used to write any data the application may require for
restoration.

VFS113 Rack/Desktop Model User’s Guide
The EC command, as implemented in the Chaparral router, requires no administration.
Administering an EC environment is most intensive on the application side. Chaparral
supports the Storage Networking Industry Association Extended Copy Specification
(ANSI T10/ 99-143R1). Any questions related to using a Chaparral router in an EC
environment should be directed to the application provider or your reseller. If you are
developing EC enabled applications, contact Chaparral for information on our specific
implementation.

VFS113, and assigns each device a unique LUN address, which will be mapped as part of
a unique FC address. You can configure the router to assign itself a LUN for in-band
management, server-free backup, and other uses.
To make the host FC connection:
1 Connect the Fibre Channel cable to the router and the host computer, hub, or switch.
2 Power up connected servers, hubs, or switches on the network if necessary.
Understanding the LED Status Lights
LED status lights are on the rear panel of the router. For information about troubleshooting

Changing the Mapping Mode (AUTO or FIXED)
You can change how the router maps the addresses of the devices on the SCSI channels to
FC LUNs. You have two options for the mapping mode, which affects all three SCSI
channels on the VFS113:
I
AUTO—lets the router assign an FC LUN to each device anytime you power up the
router. The router maps sequentially as it scans the channels and discovers devices
(devices are discovered by channel, lowest SCSI ID and LUN first). Devices are
mapped to FC LUNs, starting from LUN 0 to LUN 63 (64 LUNs are supported).
I
FIXED—locks the current mapping for each device. This reserves the devices’ same
FC LUN over power cycles (SCSI channel:target:LUN combination), even when you
power down and power up the router. The router also retains the mapping, if the
devices are added, moved, or removed. The FIXED mode is recommended for
environments where device configuration may change and a FIXED mapping from
the application to the target devices is required. Devices added after selecting FIXED
will be automatically mapped to an available FC LUN.
For example, either a disk drive or a tape drive would map to the same FC LUN if the
disk drive at a particular SCSI channel:target:LUN is replaced with a tape drive at the
same SCSI channel:target:LUN.

router.
FIXED—tells the router to keep the same FC LUN as currently assigned for each
device. This reserves the same FC LUN for each device, even when you power down
and power up the router. The router retains the FC LUN, even if the device is no
longer connected.
The system confirms that the changes are made.
4 Press Enter to return to the Address Mapping screen.
Changing Device Addresses (FC LUNs)
You can change the FC LUN for any device connected to the router. You can only change
the FC LUNs when the address mapping mode is set to FIXED. As long as you stay in
FIXED mode, all FC LUNs you change will be retained even if the device or router is
powered off and back on or if the device is removed and reconnected.
You can set the FC LUN for devices to any number between 00 and 63 by selecting the FC
LUN that you want the device to map to. You cannot select the same FC LUN as the
router’s LUN.
When in FIXED mode, the router will discover any new devices or existing devices that
were removed and reconnected to a different location. These newly discovered devices
will be in AUTO mode and will be assigned an FC LUN by the router. You can change
these FC LUNs by following the steps below.
If you assign an FC LUN that is already in use, the FC LUNs for the two devices are
swapped. For example, if device A has LUN 01 and device B has LUN 03, and you assign
03 to device A, the LUN for device B becomes 01.

Upgrading Firmware
You can upgrade the firmware for the router and the Ethernet card in the router.
Information regarding the latest release of firmware and firmware updates is available
technical support for the password to access the firmware updates.
Upgrading the Router’s Firmware
You use the Flash Utility to download new firmware (.fla file) for your router, to auto-
detect your VT-100/ANSI terminal baud rate, and to run on-board diagnostics. The Flash
Utility is resident in the embedded firmware of the router.
You access the Flash Utility using a computer with VT-100/ANSI terminal emulator
software, such as HyperTerminal, connected to the router through the serial RS-232
interface. The router auto-detects the baud rate when you hold down the space bar on the
computer while powering-on the router. Valid baud rates are 9,600, 19,200, 38,400, 57,600
and 115,200. The default baud rate is 115,200 and is recommended to expedite the
download process.
To upgrade the router’s firmware:
1 Call Chaparral technical support for information about downloading the firmware
updates.
2 From the computer connected to the router, access the Router Administrator
software.
3 From the System Menu, select Shutdown/Restart and press Enter.

your terminal emulator to this rate and still get garbage characters:
1 Turn off the power to the router.
2 Press the spacebar of your terminal emulator.
3 Turn on the power while continuing to press the spacebar. This will allow the router
to autodetect the baud rate setting.
4 When the Flash Utility appears, select 5. Run Bridge to continue to boot the router.
Note: Some terminal emulators don’t immediately change to the new
baud rate settings, and you have to exit and restart the emulator to use the
new settings.

Troubleshooting
Problem: Nothing is displayed on the terminal emulator.
Solution: The probable cause of this problem is your terminal emulator software is not
configured correctly.
Problem: Screen is updated, but won’t respond to keystrokes.
Solution:
1 Check that all the cables are connected properly.
2 Make sure the E/S switch is on S if you are trying to use the serial port.
3 Check that the correct COM port is enabled and configured.
4 Check that your terminal emulator software is configured properly.
5 Contact your authorized Chaparral distributor.
Problem: Screen looks correct, but clock is not being updated.
Solution: Check to be sure that router is still powered on. If you are using XON/XOFF,
press Ctrl-q.
Problem: Screen is updated and menus appear right, but boxes around menus look
incorrect.
Solution: Try a different font in your terminal emulator program, such as HyperTerminal.
If you cannot find a font that looks correct, set ASCII Display to Yes in the Display
options item of the Configuration menu.
Device SCSI Channel Problems
Problem: Not all drives connected to the router device channels are displayed during
boot, or the router hangs during display of connected drives and never reaches the Router
Administrator screen.
Solution: Check your JBOD or tape library documentation to be sure that the device is
properly configured. If your device supports removable drives, check the drive shuttles to
be sure that the power connectors, SCSI connectors, and SCSI ID connectors are properly
seated. Check termination and SCSI ID assignment.

Address and Device Mapping
Devices attached to the router are discovered during power on. The router defaults to
AUTO mapping mode, which automatically maps the SCSI devices at each power on. The
router maps devices sequentially as it scans the channels and discovers the devices
(devices are discovered by channel, lowest SCSI ID and LUN first). Devices are mapped
to FC LUNs, starting from LUN 0 to LUN 63 (64 LUNs are supported, including an
optional router LUN).
You can select the FIXED mapping mode to lock the current device mapping so that it
doesn’t change during subsequent power ons, even if devices are added, moved, or
removed. FIXED is recommended for environments where device configuration may
change and a fixed mapping from the application to the target devices is required. Devices
added after selecting FIXED will be automatically mapped to an available FC LUN. See
Figure A-1 on page A-2 is an example of how the router will map SCSI devices (SCSI
channel:target:LUN) to FC LUNs.

Loop ID to AL_PA Mapping
During the Fibre Channel Arbitrated Loop (FC-AL) initialization process, a unique
Arbitrated Loop Physical Address (AL_PA) value is assigned to each port on the loop. Not
all of the 256 hex values are allowed as AL_PA values per FC-AL, so Loop IDs are used
to represent the 125 addresses that the router can use. You can assign a Loop ID to the
the router attempts to obtain an available Loop ID, in the following order: 0, 1, 2, etc.

LAN Configuration
Before you can access the Router Administrator software using the Ethernet port, you
must set up your router for TCP/IP. The following sections describe the router’s TCP/IP
setup.
A router that is part of a TCP/IP network requires three basic IP configuration elements: IP
address, subnet mask, and default gateway IP address. The router’s IP address must be
unique to the network in which the router resides. If the router is part of a publicly routed
network (that is, attached to the Internet), the address must be globally unique.
This appendix describes how to configure the TCP/IP settings for the first time starting
from the factory-set defaults.
Configuring the Router for TCP/IP
Before you can access the Router Administrator software, you must set the IP address and
subnet mask for the controller. The default IP address is 10.0.0.1. You can do this one of
four ways:
I
I
I
Setting up your computer with an IP address that is compatible with the controller
default of 10.0.0.1, such as 10.0.0.42.

VFS113 Rack/Desktop Model User’s Guide
Using Address Resolution Protocol
The ARP configuration method requires no IP address re-configuration of any computer
on the network. The ARP command is available in various forms and sometimes with
varying syntax in UNIX and Windows systems.
All routers are shipped with a unique Media Access Control (MAC) hardware address
(sometimes referred to as a physical address). Chaparral Network Storage MAC addresses
have the format “00-50-13-fx-xx-xx,” where “x-xx-xx” is unique to each router. The
router MAC address can be found on a label on the bottom of the router.
Note: TCP/IP protocol requires that all devices in a subnet have the same
octets, typically for the first three octets. For example, to use the default
Chaparral IP address of 10.0.0.1, other computers on the subnet must be
10.0.0.X, where X is the value between 2 and 254. ARP is useful because
you can temporarily assign a compatible IP address to the router.
To use ARP to resolve addresses in Windows:
1 You must first place the MAC address of the router being set up into your computer’s
ARP cache using the following command:
arp -s [IP address] 00:50:13:fx-xx-xx.
In this command, 00-50-13-fx-xx-xx is the router’s unique MAC address and IP
address is the IP address you or your LAN system administrator have chosen to use
as the IP address for the router.
This ARP command adds a static MAC-to-IP address binding to your computer. For
example, if you wanted to bind the router with the factory MAC address of 00-50-13-
f0-10-00 to the IP address 169.205.7.22, you should type arp –s 169.205.7.22 00-50-
13-f0-10-00.
Note: UNIX users see MAN Pages for ARP in your OS.
2 After entering the MAC address-to-IP address mapping into your computer’s ARP
cache, you can issue the command ping 169.205.7.22 to send a request to the router.
If the router addressed by the ping command does not respond, check the LAN
connection on the router.
3 If the ping command addressed to the router was successful, use Telnet to access the
router using the IP address you just configured (for example, 169.205.7.22).
4 Access the TCP/IP Configuration screen and enter the permanent IP address for the
router.

LAN Configuration
Dynamic Host Configuration Protocol Configuration
The Dynamic Host Configuration Protocol (DHCP) is a protocol designed to make IP
address assignment dynamic and automatic. When a router is configured in DHCP mode,
it generates a request for an IP address. The address is provided to the router and can be
used from that point forward.
In the dynamic address assignment mode, an IP address is leased to a DHCP-configured
router. You should ask your system administrator to configure your network so the router
can use DHCP and host name you have assigned to the router.
In the event you configure your router to DHCP and do not know which IP address was
assigned automatically, you can use ARP to discover which IP address was assigned to the
router by the DHCP server.
To discover which IP address was assigned to the router:
1 Follow the steps in the previous section for ARP to bind the router MAC address to a
temporary static IP address.
2 Use the command arp –g to display your computer’s the IP-to-MAC address table.
This table contains two entries corresponding to the router MAC address. One of the
entries contains the temporary static IP address you just bound to the router MAC
address, and the other entry is the DHCP-assigned IP address. You can use the DHCP
assigned address to access the router from any computer on the network.
Configuring the Additional LAN Settings
You can configure the following additional LAN settings:

Glossary
“A” controller—In Active-Active mode, one controller is designated as the “A”
controller and the other controller is designated as the “B” controller. Controller identity is
determined by enclosure hardware. The controller’s identity displays continuously at the
bottom of the Disk Array Administrator screens.
Address—An address is a data structure or logical convention used to identify a unique
entity, such as a particular process or network device.
Arbitrated loop physical address (AL_PA)—An AL_PA is a 1-byte value used in
an arbitrated loop topology. This value is used to identify L_Ports. The value then
becomes the last byte of the address identifier for each public L_Port on the loop.
Bus—See Channel.
Channel—A channel is a common physical path composed of wires or other media,
across which signals are sent from one part of a computer to another. A channel is a means
of transferring data between modules and adapters, or between an adapter and SCSI
devices. A channel topology network consists of a single cable trunk that connects one
workstation to the next in a daisy-chain configuration. All nodes share the same medium,
and only one node can broadcast messages at a time.
Fabric—Fabric refers to a switched topology, which is one of the three FC topologies.
Fabric elements, which are responsible for frame routing, interconnect various N_Ports or
NL_Ports. Depending on vendor support, fabric switches may be interconnected to
support up to 16 million N_Ports on a single network.
Failback—In Active-Active mode, failback is the act of returning ownership of
controller resources from a surviving controller to a previously failed (but now active)
controller. The resources include disk arrays, cache data, and host ID information.
Failover—In Active-Active mode, failover is the act of temporarily transferring
ownership of controller resources from a failed controller to a surviving controller. The
resources include disk arrays, cache data, and host ID information.
FC adapter—An FC adapter is a printed circuit assembly that translates data between the
FC host processor’s internal bus and FC link.
FC Arbitrated Loop (FC-AL)—FC-AL is one of three FC topologies in which ports
use arbitration to establish a point-to-point circuit. Arbitrated loops allow multiple ports to
be connected serially in a single loop. Up to 126 NL_Ports and 1 FL_Port can be
configured in a unidirectional loop. Ports arbitrate for access to the loop based on their
AL_PA. Ports with lower AL_PAs have higher priority than ports with higher AL_PAs.
FC device—A device that uses FC communications is referred to as an FC device.
FC port—An FC port is the opening at the back of a router that provides a fiber optic
connection between the FC adapter and FC host.
FC protocol for SCSI (FCP)—FCP defines an FC mapping layer (FC-4) that uses FC-
PH services to transmit SCSI command, data, and status information between a SCSI
G-1

VFS113 Rack/Desktop Model User’s Guide
initiator and SCSI target. FCP enables transmission and receipt of SCSI commands, data,
and status across the FC using standard FC frame and sequence formats.
Fibre—Fibre is a generic FC term that refers to all transmission media types specified in
the FC Physical Layer standard (FC-PH), such as optical fiber, copper twisted pair, and
copper coaxial cable.
Fibre channel (FC)—FC is a bidirectional, point-to-point serial data channel, structured
for high-performance capability. In the physical sense, an FC is an interconnection of
multiple communication points, called N_Ports, by a switching network (fabric). FC
transports incoming data from devices by reading the buffer information, packaging it, and
sending the information across the fabric. Although FC is a generalized transport
mechanism that has no protocol of its own or native I/O command set, it can transport any
existing upper-level protocol such as SCSI and IP. FC offers high-speed data transfer rates
up to 1 Gbps. FC is most commonly used to connect clustered servers to storage systems.
ANSI has developed standards for FC.
Gigabit interface converter (GBIC)—A GBIC, also referred to as a Physical Link
Module, is a physical component that manages functions of the FC-0 layer. This layer
consists of the physical characteristics of the media and interface, including drivers,
transceivers, connectors, and cables. A GBIC attaches to an FC adapter and connects a
router to an FC host.
High voltage differential (HVD)—HVD is a differential SCSI scheme with
terminators that run on 5 volts.
Host bus adapter (HBA)—An HBA is the critical link between a host server or
workstation and a storage subsystem, integrating computing platforms, operating systems,
and I/O protocols to ensure proper interoperability and functionality. The bus adapter
provides direct storage connectivity from the system to data within the storage subsystem
and enables stable, high-speed transmission of information and files. HBAs manage the
controller-specific aspects of handling a storage driver interface device implemented as a
target driver, which supports mass storage peripheral devices such as disks and tapes. A
storage driver interface is used to implement SCSI and other storage device drivers. An
HBA connects to the storage subsystem to the host computer and uses either fiber or
copper media.
Initiator—An initiator is an FC or SCSI device that contains application clients that
originate service requests and task management functions for processing by a target FC or
SCSI device.
Initiator mode—Initiator mode is the configuration mode of a device in which an FC or
SCSI initiator requests operations to be performed by an FC or SCSI target device.
Kill—In Active-Active mode, one controller can kill the other controller by resetting it
and taking it offline.
Logical unit number or logical unit (LUN)—A LUN is a subdivision of a SCSI
target. For SCSI-3, each SCSI target supports up to 128 LUNs. An FC host using LUNs
can address multiple peripheral devices that may share a common controller.
Loop address—Loop address is an FC term that indicates the unique ID of a node in FC
loop topology. A loop address is sometimes referred to as a Loop ID.

Glossary
Low voltage differential (LVD)—LVD is a method of powering SCSI cables that will
be formalized in the SCSI-3 specifications. LVD uses less power than the current
differential drive (HVD), is less expensive, and allows for higher speeds such as those of
Ultra2 SCSI. LVD requires 3.3 volts (versus 5 volts for HVD).
Management information base (MIB)—A MIB is a database of managed objects
accessed by network management protocols. An SNMP MIB is a set of parameters that an
SNMP management station can query or set in the SNMP agent of a network device (for
example, a router).
Mapping table—A mapping table is a table indexed by sequential LUN values. The
values indicate select bus:target:LUN devices. Mapping tables are used by some routers to
perform FC-to-SCSI operations by default.
Other controller—In Active-Active mode, the opposite controller from the one
currently being used (that is, not the local controller) is referred to as the other controller.
Ownership—In an active-active configuration, a single controller has ownership of the
following resources: arrays and dedicated spares. When a controller fails, the other
controller assumes temporary ownership of its resources.
Point to Point—A point-to-point connection is a communication link between two end
systems. Chaparral uses this term to refer to a link between the controller or router (N-
port) and the F-port on a switch. The point-to-point topology is one of three FC topologies,
in which two ports are directly connected by a link; there are no fabric, loop, or switching
elements present.
Router—A router is a device that enables connectivity between SCSI devices and FC
networks. It routes each data command to the appropriate SCSI channel based on the
address it is intended for.
SCSI adapter —A SCSI adapter is a 16-bit fast/wide or 8-bit narrow, single-ended or
differential physical connection between a router and SCSI devices. Each SCSI adapter
supports up to 16 (fast/wide) or 8 (narrow) SCSI devices, including itself.
SCSI addressing—Each device supported by a SCSI adapter has its own unique SCSI
address, which dictates the device’s priority when arbitrating for access to the SCSI bus. A
SCSI address of 7 has the highest priority. For a fast/wide SCSI adapter that supports up to
16 devices, the next highest priority address is 6, then 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10,
9, and 8. A narrow SCSI adapter supports up to eight devices, including itself. The SCSI
address 7 has the highest priority, followed by 6, 5, 4, 3, 2, 1, and 0.
SCSI bus—A SCSI bus provides a means of transferring data between SCSI devices. A
SCSI bus is either an 8- or 16-bit bus that supports up to 8 or 16 devices, including itself.
The bus can consist of any mix of initiators and targets, with the requirement that at least
one initiator and one target must be present.
SCSI device—A SCSI device is a single unit on a SCSI bus that originates or services
SCSI commands. A SCSI device is identified by a unique SCSI address. SCSI devices can
act as initiators or targets.
SCSI port—A SCSI port is an opening at the back of a router that provides connection
between the SCSI adapter and SCSI bus.

Simple Network Management Protocol (SNMP) —SNMP is the Internet standard
protocol, defined in STD 15, RFC 1157, developed to manage nodes on an Internet
Protocol (IP) network.
Small computer system interface (SCSI) —SCSI is an industry standard for
connecting peripheral devices and their controllers to an initiator. Storage devices are
daisy-chained together and connected to a host adapter. The host adapter provides a shared
bus that attached peripherals use to pass data to and from the host system. Examples of
devices attached to the adapter include disk drives, CD-ROM discs, optical disks, and tape
drives. In theory, any SCSI device can be plugged into any SCSI controller.
Speed—Speed is a status type in the FC Status Menu that shows the speed (1,063 Mbps)
of the FC adapter.
Storage area network (SAN)—SAN refers to the network behind servers that links
one or more servers to one or more storage systems. Each storage system could be RAID,
tape backup, tape library, CD-ROM library, or JBOD. SANs operate with both SCSI and
networking (IP) protocols. Servers and workstations use the FC network for shared access
to the same storage device or system. Legacy SCSI systems are interfaced using an FC-to-
SCSI bridge.
Target—A target is a device (peripheral) that responds to an operation requested by an
initiator (host system). Although peripherals are generally targets, a peripheral may be
required to act temporarily as an initiator for some commands (for example, SCSI
EXTENDED COPY command).
Terminator block/termination—A terminator block (or termination) refers to the
electrical connection at each end of a SCSI bus. The terminator block is composed of a set
of resistors, or possibly other components. The function of a terminator block is to provide
a pull-up for open collector drivers on the bus, and also impedance matching to prevent
signal reflections at the ends of the cable. SCSI buses require that a terminator be placed
on the 68-pin high-density SCSI connector on the last SCSI peripheral. Data errors may
occur in a SCSI bus that is not terminated.
Topology—A network topology refers to the physical layout of nodes on a network.
Topologies range from local network topologies to WAN topologies. FC topologies
include point-to-point, FC-AL, and fabric.
Trap—In the context of SNMP, a trap is an unsolicited message sent by an agent to a
management station. The purpose is to notify the management station of some unusual
event.
Unkill—In Active-Active mode, when a surviving controller removes the reset from the
other controller, it unkills it. The other controller will reboot and attempt to come online.
