About this Guide
This Sun StorageTek 2500 Series Array Hardware Installation Guide describes how to
install rack-mounting rails and array trays in a cabinet. This document also provides
information to physically set up and connect your array to a host. Afterwards,
information is provided to apply power and to add network functionality, including
storage management (multipath/failover), IP addressing, iSCSI, and DHCP.
The terminology used in this document refers to the Sun StorageTek 2500 Series
arrays. There are three styles of controller trays, each with different host interface
ports (iSCSI, SAS, or FC). There is also the drive expansion tray, which enables the
Sun StorageTek 2500 Series arrays to have more disk drives attached. The
components that slide into the trays are called CRUs or modules. The terms you
might see in this document are: controller (or controller module), power-fan module,
I/O module, and disk drive.
Array management, data host management, and remote command line interface
(CLI) functions are performed by the Sun StorageTek Common Array Manager
(CAM) software. For installation and initial configuration of the Sun StorageTek 2500
Series array, including firmware upgrades, initial array setup, partitioning domains,
configuring storage, and configuring IP addressing, see the Sun StorageTek Common
Array Manager Software Installation Guide.

Sun StorageTek 2500 Series Array
Overview
The Sun StorageTek 2540 Array, the Sun StorageTek 2530 Array, the Sun StorageTek
2510 Array, and the Sun StorageTek 2501 Expansion Tray are a family of storage
products that provide high-capacity, high-reliability storage in a compact
configuration.
The Sun StorageTek 2500 Series Array is a modular, rack-mountable controller tray.
It is scalable from a single controller tray configuration to a maximum configuration
of one controller tray and three additional drive expansion trays. This would create
a storage array configuration with a total of 48 drives attached behind the controllers
(one controller tray and three drive expansion trays).
All four of the trays can be installed in the following cabinets:
■
Sun Rack 900/1000 cabinet
■
Sun StorageTek Expansion cabinet
■
Any 19-inch wide, 4-post, EIA-compatible rack or cabinet with a front-to-back
depth between vertical cabinet rails of 61cm to 91cm (24 in. to 36 in.). The cabinet
can have threaded or un-threaded cabinet rails.
The Sun StorageTek 2540 Array, the Sun StorageTek 2530 Array and the Sun
StorageTek 2510 Array contains disk drives for storing data. The controller tray,
typically with two controller modules, provides the interface between a data host
and the disk drives. The Sun StorageTek 2540 Array provides a Fibre Channel
connection between the data host and the controller tray. The Sun StorageTek 2530
Array provides a Serial Attached SCSI (SAS) connection between the data host and
the controller tray. The Sun StorageTek 2510 Array provides iSCSI connections using
Ethernet between the data host and the controller tray.
The Sun StorageTek 2501 drive expansion tray provides additional storage. You can
attach the drive expansion tray to any of the 2500 series arrays.
You manage the array with the Sun StorageTek Common Array Manager software.

Controllers
The Sun StorageTek 2540, 2530, and 2510 Arrays usually have two controllers
(single-controller configurations are available, but are not recommended). The
controllers manage the input/output (I/O) between the volumes and the data host.
The controllers have an Ethernet connection to the management host for out-of-band
management and contain a battery that provides backup power to the cache memory
for up to three days in the event of a power loss.
Because each controller tray contains two controllers, the data path through one
controller can fail and the other controller provides a redundant data path to all of
the disk drives. If a controller fails, you can replace the failed controller while the
power is applied and the storage array is processing data (a hot swap).
Note – Replacement controllers might not be at the same level of firmware. If
necessary, use CAM to upgrade the firmware for the new controller so that it
matches the configuration database (baseline firmware release level or later).
Chapter 1
Tray Overviews

Each controller has a media access control (MAC) address that identifies it on the
network. The MAC address for a controller is on a label on the controller. The MAC
address label is attached to the controller at the rear of the tray near the serial port.
The tray ID numbers are set by the trays themselves on first power on. However,
you can change the setting through the Common Array Manager software. The tray
ID numbers on both of the controllers in one controller tray are identical under
optimal operating conditions.
Sun StorageTek 2540 Array
This Fibre Channel (FC) controller tray provides the following capabilities:
■
Two Fibre Channel data host ports per controller with 1, 2, or 4 Gb/s data host

SFP Transceivers
You can connect the Sun StorageTek 2540 Array to either copper host interface cables
or fiber optic host interface cables. If you use fiber-optic cables, you must install an
SFP transceiver in each interface port on the controller where a fiber-optic cable is to
be installed. The SFP transceiver is required to translate the optical signals from the
fiber-optic cable into digital signals for the controller.
Note – The SFP transceiver shown might look different from those that are shipped
with your controller tray. The difference does not affect transceiver performance.

Controller Tray and Drive Expansion Tray PowerFan Assembly
The power-fan assembly for the Sun StorageTek 2540 Array, the Sun StorageTek 2530
Array, and the Sun StorageTek 2510 Array is identical and interchangeable.
Note – A minimum of two disk drives must be operating in a controller tray or in a
drive expansion tray to avoid generating a power-fan assembly error.
The power-fan assembly contains an integrated cooling fan. The power supply
provides power to the internal components by converting incoming AC voltage to
DC voltage. The fan circulates air inside of the tray by pulling air in through the
vents on the front of the assembly and pushing the air out of the vents on the back
of each fan.
Each tray contains two power-fan assemblies. If one power supply is turned off or
malfunctions, the other power supply maintains electrical power to the tray.
Likewise, the fans provide redundant cooling. If one of the fans in either fan housing
fails, the remaining fan continues to provide sufficient cooling to operate the tray.
The remaining fan runs at a higher speed until the failed fan is replaced. Replace the
failed fan as soon as possible.
Sun StorageTek 2501 Expansion Tray
The drive expansion tray expands the storage capacity of a storage array. The
controllers in the controller tray can connect to the drive expansion tray and access
the disk drives in the drive expansion tray for additional storage. A drive expansion
tray contains both physical components (disk drives, Input/Output Modules
(IOMs), and power-fan assemblies) and logical components (virtual disks and
volumes).
Expansion Tray IOM
The expansion tray contains two IOMs that provide the interface between the disk
drives in the expansion tray and the controllers in the controller tray. Each controller
in the controller tray connects to an IOM.
If one IOM fails, the other IOM provides a redundant data path to the disk drives.
You can replace a failed IOM while the power to the storage array is turned on and
the storage array is processing data (a hot swap).
14
Sun StorageTek 2500 Series Array Hardware Installation Guide • May 2010
Drive Expansion Tray IOM Ports
The IOM uses SAS cables to enable the controller tray to communicate with the disk
drives in the drive expansion trays. Each IOM in a drive expansion tray has two SAS
expansion ports. One port shows an up arrow, and the other port shows a down
arrow.
FIGURE 1-10
SAS Ports on the Expansion Tray IOM
1. SAS Port (Up Arrow)
2. SAS Port (Down Arrow)
3. Serial Port
When connecting the SAS cable from an IOM in one drive expansion tray to an IOM
in another drive expansion tray, connect from a port with a down arrow to a port
with an up arrow.
Note – If the cable is plugged into two ports with arrows of the same direction,
communication between the two drive expansion trays is lost.

Service Action LEDs
Each controller, power-fan assembly, IOM, and disk drive has a Service Action
Allowed LED. The Service Action Allowed LED indicates when you can remove a
component safely. See “LEDs on the Rear of the Trays” on page 16 for the locations
and descriptions of the Service Action Allowed LEDs on a controller tray and a drive
expansion tray, and see “LEDs on the Disk Drives” on page 25 for disk drive Service
Allowed LEDs.
Caution – Potential loss of data access – Never remove a power-fan assembly, a
controller module, or a disk drive unless the Service Action Allowed LED is turned
on or you are given specific instructions to do so by the Service Advisor feature of
the Common Array Manager software.
If a CRU or module fails and must be replaced, the Service Action Required LED on
that module turns on to indicate that a service action is required. The Service Action
Allowed LED turns on if it is safe to remove the CRU or module. If there are data
availability dependencies or other conditions that dictate that a CRU or module
should not be removed, the Service Action Allowed LED remains off.
The Service Action Allowed LED automatically turns on or turns off as conditions
change. In most cases, the Service Action Allowed LED turns on when the Service
Action Required (Fault) LED is turned on for a CRU or module.
Note – If the Service Action Required (Fault) LED is turned on but the Service
Action Allowed LED is turned off for a particular CRU or module, you might have
to service another component first. Check the Service Advisor feature of the
Common Array Manager software to determine the action you should take.

Preparing the Cabinet
Select the cabinet in which you will be installing the array. Be sure the cabinet is
installed as described in the installation instructions provided with it.
1. Stabilize the cabinet as described in the cabinet documentation.
2. If the cabinet has casters, make sure the casters are locked to prevent the
cabinet from rolling.
3. Remove or open the front panel.
4. Remove or open the vented back panel.
Planning the Order of the Tray Installation
Install the trays starting with the controller tray at the lowest available 2U tray slot
in the cabinet. Next, install the expansion trays for the first controller tray. If room
remains in the cabinet, repeat for the next controller tray and expansion trays.
Starting at the bottom distributes the weight correctly in the cabinet.
Tip – If you plan on adding hosts to the cabinet, make sure that you have cables of
sufficient length to reach their controller tray.
32
Sun StorageTek 2500 Series Array Hardware Installation Guide • May 2010
Attaching the Rails to a Cabinet
Depending on the type of cabinet in which you will install the tray, use one of the
following procedures to attach the rails:
■
“Attaching the Universal Rail Kit to a Standard Sun or 19-Inch Cabinet With
Threaded Cabinet Rails” on page 33
■
“Attaching the Universal Rail Kit to a Standard 19-Inch Cabinet With Unthreaded Cabinet Rails” on page 37
Each tray requires two standard mounting rack units (2RU) of vertical space in the
cabinet. Most cabinets have a “U” mark on their vertical rail with three mounting
holes in the left cabinet vertical rail and in the right cabinet vertical rail. The top
mounting hole of the lower RU is always closest to the bottom mounting hole of the
upper RU, hence the division between RUs on a cabinet rail is between the two
closest mounting holes in a grouping.
The universal rails have an adjustable depth of 24” to 34”.
Attaching the Universal Rail Kit to a Standard
Sun or 19-Inch Cabinet With Threaded Cabinet
Rails
This procedure describes the steps to attach the universal rail kit to:
■
All standard Sun cabinets, including the Sun Rack 900/1000 cabinets
■
Sun StorageTek Expansion cabinets
■
All 19-inch wide, 4-post EIA-compatible racks and cabinets with the following
cabinet rail types:
■
M5 threaded
■
M6 threaded
■
10-32 threaded
■
12-24 threaded
■
circular un-threaded
1. To attach the universal rail kit to a cabinet with these cabinet rail types,
position the front flange of the left universal rail behind the left front cabinet
rail (FIGURE 2-2).
Chapter 2
Installing Trays
33
Note – The U marks are not labeled on all racks, as they are on the Sun cabinets.
The rule of thumb to remember is that the division of RUs passes between the two
closest rail holes in each set of holes (see FIGURE 2-2).
FIGURE 2-2

Installing a Tray in a Cabinet
Install the controller tray in the first empty 2RU slot at the bottom of the cabinet. If
you are installing expansion trays, continue installing the trays from the bottom up.
1. Using two people, one at each side of the tray, carefully lift and rest the tray on
the bottom ledge of the left and right rails (FIGURE 2-12).
Caution – Use care to avoid injury. A tray can weigh up to 55 pounds (25 kg).
42

2. Carefully slide the tray into the cabinet until the front mounting flanges on the
tray touch the vertical face of the cabinet (FIGURE 2-13).
Chapter 2
Installing Trays
43
FIGURE 2-13
Controller Tray Installed
The tray has mounting flanges on both sides with three mounting holes in them. The
top and bottom holes are large enough to fit over the heads of the screws already in
the cabinet rails used to mount the universal rails. If the tray was shipped with end
caps (bezels) clipped on the tray mounting flanges, remove them before sliding the
tray all the way in over the mounting screw heads.
To remove an end cap, place your thumb on the lower front face of the cap and reach
your forefinger underneath to the back bottom edge of the cap, then pull the cap
towards you and slightly upwards.
On the rear of the controller tray, a flat metal tab on each side corner slides into a
special mounting clip on the rear of each universal rail, securing the back of the tray.
This eliminates the need for rear mounting screws to secure the tray. For racks that
might move or be shipped, Sun recommends that you install M4 screws through the
hole in the tab and into the corresponding threaded hole in the rail as shown in
FIGURE 2-14.
44

Connecting the Power Cables
1. Verify that both power switches are turned off.
2. Verify that the circuit breakers in the cabinet are turned off.
3. Connect each power supply in the tray to a separate power source in the
cabinet.
4. Connect the primary power cables from the cabinet to the external power

Inter-tray Cabling
This section describes how to cable a controller tray to the drive expansion trays for
several different configurations. Each controller has one expansion port (FIGURE 2-16).
Controller A controls drive channel 1 through the A-side modules; Controller B
controls drive channel 2 through the B-side modules. Each drive channel provides a
separate path for data transfer from the controller tray to the expansion trays; the
two channels provide redundancy.

Array Configuration Naming Convention
The configuration naming convention is “controller trays x trays” where the first
number is the controller tray and the second is the sum of the controller tray and the
number of drive expansion trays. For example, 1x1 is a standalone controller tray,
1x2 is the controller tray and one expansion tray, 1x3 is the controller tray and 2
expansion trays (TABLE 2-1).

Sun StorageTek 2500 Series Array Hardware Installation Guide • May 2010
Connecting Drive Expansion Trays
Keep the following points in mind when adding expansion trays to your storage
array:
■
Once the drive expansion tray is physically installed, the expansion trays should
be turned on and connected to the array with power on. The array must be at an
optimal status with I/O data transfer turned off. If you need to add an expansion
tray to a storage array that cannot be taken off-line, contact your Sun Technical
Support representative before attempting to connect the new tray.
■
Controller trays and expansion trays are shipped with protective plastic plugs in
the SAS expansion ports. You must remove these before connecting cables.
■
Expansion trays are added serially, in a chain (actually two chains: channel one
through the A-side controller and I/O modules, and channel two through the Bside controller and I/O modules). The SAS cable from the expansion port on a
controller connects to the In port (Up arrow) on an expansion tray I/O module.
The SAS cable from an I/O module on expansion tray 1 to a corresponding I/O
module on expansion tray 2 connects from the Out port on expansion tray 1 to the
corresponding In port on expansion tray 2. This pattern repeats for each
additional drive expansion tray on a channel. See FIGURE 2-20 for an illustration of
this reverse cabling pattern.
■
To connect cables for maximum redundancy, controller B must be cabled to the
expansion tray B-side I/O modules in the opposite order as the expansion tray Aside I/O modules. That means the last I/O module in the A-side chain from
controller A must be the first I/O module in the B-side chain from controller B. See
FIGURE 2-20 for an illustration of cabling for maximum tray level redundancy.
■
On all SAS cables, affix a label to each end of the cable. See “Tray Interconnect
Cable Labeling” on page 53 for labeling tips.

Cabling an Expansion Tray to a Controller Tray
A Controller tray has two expansion ports, one on Controller A and one on
Controller B. To connect a drive expansion tray, connect an SAS cable from each
expansion port on the controller to each In port on the expansion tray. FIGURE 2-18
shows a 1x2 array configuration consisting of one controller tray and one drive
expansion tray. Two SAS cables are required.
FIGURE 2-18
1x2 Array Configuration Cabling Example

To cable a 1x2 array configuration:
1. Locate the Controller A and Controller B expansion ports at the back of the
controller tray (FIGURE 2-16).
2. Locate the In and Out expansion ports at the A-side and B-side back of the
expansion tray (FIGURE 2-17).
3. Connect one SAS cable between the Controller A expansion port and the Aside In port on the expansion tray (FIGURE 2-18).
4. Connect one SAS cable between the Controller B expansion port and the B-side
In port on the expansion tray (FIGURE 2-18).
Cabling an Expansion Tray to Another Expansion
Tray
Each additional expansion tray is added to the preceding expansion tray by
connecting SAS cables from the Out ports of the first tray to the In ports of the next
tray. FIGURE 2-19 illustrates a 1x3 storage array configuration consisting of one

controller tray and two expansion trays. The cable connections on the B-side are
reversed (the cable from the controller A expansion port goes to the In port of
expansion tray 1; the cable from the controller B expansion port goes to the In port
on expansion tray 2) for maximum redundancy. This pattern continues for each
additional tray you add. Two more SAS cables are required for each additional tray.

8. Connect one SAS cable between the expansion tray 2 B-side Out port and the Bside In port of expansion tray 1 (FIGURE 2-20).
Tray Interconnect Cable Labeling
Labels for the drive-side interface cables identify which controller ports and which
I/O module ports in an expansion tray you use when you attach cables between a
controller tray and the drive expansion tray. Cable labels are useful if you need to
disconnect cables to service a controller.
Attach a label to each end of the cable. Use this design to create labels for drive
cables:
■
Controller ID (for example, Controller A)
■
Drive expansion tray ID (for example, Tray A)
■
Expansion port ID (for example, In or Out)
■
I/O module ID

Using this design, the label includes the following information:

Single-Controller Configurations
This configuration has a single controller and a single back-end channel. By
definition, there is a single path connection to the data host, and no redundancy is
available. There can be drive expansion trays on the single back-end channel.
The cabling is the same as the cabling on a single channel of an ordinary array, such
as that shown on the A-side in FIGURE 2-18. CRU removal and replacement
procedures in a single-controller configuration are the same as those for a dualcontroller configuration with a failed controller (with the exception of the service
procedures targeted at the failed controller). These procedures are available in
Service Advisor. Maintenance procedures such as firmware updates or servicing of
the controller tray or drive expansion trays will cause loss of access to the storage
array during the performing of the procedure, since there is no backup channel.
Performance and default behavior are the same as a dual-controller configuration
with a failed or missing controller. Write cache is by nature in write-through mode
because there is no cache mirroring possible.

To attach the Ethernet ports to the local area network (LAN) of the management host:
1. Locate the Ethernet port for Controller A and Controller B at the back of the
controller tray (FIGURE 3-1).
2. Connect Ethernet cables to the Ethernet ports of each controller.
3. Connect the other end of each Ethernet cable to the LAN on which your
management host resides (preferably on the same subnet).
Attaching the Ethernet Ports to the Management
Host Using an Ethernet Hub
To attach the Ethernet ports and the management port Ethernet interface to an
Ethernet hub on a private subnet:
1. Locate Ethernet ports on Controller A and Controller B at the back of the
controller tray (FIGURE 3-1).
2. Connect Ethernet cables to the Ethernet ports of each controller module.
3. Connect the other end of each Ethernet cable to an Ethernet hub.
4. Connect an Ethernet port on the management host to the Ethernet hub.
56

iSCSI. It contains the following sections:
■

■
“Next Steps” on page 62
Connecting Data Hosts to the 2510 Array
The Sun StorageTek 2510 Array is an Internet Small Computer System Interface
(iSCSI) system that communicates with hosts over an Ethernet data path.
The hosts that initiate data need a NIC as noted in “iSCSI Concepts” on page 98.
For initial iSCSI configuration information, go to Appendix C.
Note – For maximum hardware redundancy, each host must have a minimum of
two Ethernet NICs for dual paths. Dual-port NICs give you two paths into the
storage array, but do not ensure redundancy if the NIC fails. Single controller and
single path configurations are supported, but are not recommended.
As shown in FIGURE 4-1, each 2510 controller has two Ethernet host ports for data
path transmission with the hosts.
59
FIGURE 4-1

The most common topologies to connect from the host to the controllers are:
■
Direct topology – Connecting directly from the hosts to the controllers.
■
Network topology – Connecting from the hosts to the controllers through a
switch or other network components. Also called a fabric or switched topology.
Alternate topologies such as single-controller configurations and mixed
configurations are described in Appendix D.

Relocation Cautions
Use the following guidelines when relocating trays or drives from one storage array
to another.
Caution – Potential data loss – Moving a storage array or array components that are
configured as part of a volume group can result in data loss. To prevent data loss,
always consult a Customer Support representative before relocating configured
drives, controller trays, or drive expansion trays.
Do not move controller trays or drive expansion trays that are part of a volume
group configuration. If you must move array components, contact a Customer
Support representative for procedures. A Customer Support representative might
direct you to complete several tasks prior to undertaking the relocation. These tasks
might include:
■
Creating, saving, and printing an array profile of each storage array that is
affected by the relocation of a drive or tray.
■
Performing a complete backup of all data on the drives that you intend to move.
■
Verifying that the volume group and each of its associated volumes on the

The Sun StorageTek 2540 Array controller tray has four Fibre Channel (FC) host
ports, two per controller module (FIGURE 6-5).
Data transmission from the host to the array controller modules is through fiberoptic cables. The fiber-optic cables connect to the controllers through Small Formfactor Pluggable (SFP) transceivers (FIGURE 6-6). To maintain redundancy, connect
two data paths from each host, one to each controller.

Before Powering On
You should decide on a IP address method before powering on. The controllers will
obtain IP addresses from DHCP if it is available on the network. If DHCP is not
available, the controller tray defaults to internal static IP addresses. (See the Sun
StorageTek Common Array Manager Software Installation Guide for information about
configuring IP addresses on controller modules.)
For instructions on configuring IP addresses on the controllers using the serial
interface, see “Configuring the IP Address of the Controller Modules” on page 90.
For an example of how to set up the DHCP server, see “Configuring a DHCP Server”
on page 139.
77
Powering On the Storage Array
Use this procedure to turn power on for all trays installed in the cabinet (FIGURE 7-1).
Note – The order in which you power up the trays is important. Be sure to power
on the controller tray last in order to ensure that the disks in the drive expansion
trays have enough time to spin completely before being scanned by the controllers in
the controller tray.

2. Turn on the cabinet circuit breakers, if applicable.
3. Press the power switches at the back of each expansion tray to the On position.
While the tray powers on, the green and amber LEDs on the front and back of the
controller tray turn on and off intermittently. Depending on your configuration, it
can take several minutes for the tray to power on. When the power-on sequence is
complete, the LEDs are steady green.
Wait until all the disk drive indicator lights on the expansion trays are steady

Sun StorageTek 2500 Series Array Hardware Installation Guide • May 2010
■
The green OK/Power LED on the tray is steady on.
If all tray and drive OK/Power LEDs are steady green and the amber Service
Required LEDs are off, the power-on sequence is complete and no faults have
been detected.
Powering Off the Array
The array rarely needs to be powered off. You remove power only when you plan to
physically move the storage array to another location or are adding additional trays
to a controller tray.
To power off the storage array, do the following:
1. Stop all I/O from the hosts, if connected, to the storage array.
2. Wait approximately 2 minutes until all disk drive LEDs have stopped flashing.
Note – If Disk Scrubbing is enabled, the disk drive LEDs will continue to flash after
the 2-minute period has elapsed. By waiting the 2-minute period, you ensure that
the data residing in cache has been written to disk. The LED flash rate during disk
scrubbing (slow, periodic blink) is different from the flash rate of I/O (fast, random).
After the 2-minute period, data residing in cache is written to disk and the battery
mechanisms are disengaged.
3. Check the Cache Active LED on the controller (FIGURE 1-11) to determine if any
outstanding cache needs to be written.
If the LED is on, there is still data that needs to be flushed and written to disk.
4. Ensure that the Cache Active LED is no longer flashing before powering off the
storage array.
5. Press each power switch at the back of the controller tray to the Off position.
6. Press the power switches at the back of each drive expansion tray to the Off
position.

Data Host HBAs and Software for
the 2540 and 2530 Arrays
This chapter describes how to install data host software, HBAs, and other software
on different host platforms. It contains the following sections:
■
“Data Host Software” on page 81
■
“Setting Up a Data Host On a Solaris System” on page 82

“Next Steps” on page 88
Data Host Software
The data host software contains tools that manage the data path I/O connections
between the data host and the storage array. This includes drivers and utilities that
enable storage management hosts to connect to, monitor, and transfer data in a
storage area network (SAN).
Note – Some management hosts can also be used as data hosts.
For information on configuring iSCSI and data hosts, refer to “Configuring iSCSI on
the Sun StorageTek 2510 Array” on page 97.
81
HBAs and Drivers
A Host Bus Adapter (HBA) enables communications between the host and the
controller tray (or other devices in-between). It also manages all data I/O on your
data host. The specific HBAs you need depend on the host server platform,
operating system, data transport (SAS, FC, or iSCSI) aka host interface, and data
transfer rates used in your storage area network. HBAs must be ordered separately,
from Sun or their respective manufacturers. Sun HBAs can be ordered from:
http://www.sun.com/storagetek/networking/
The required versions of HBA drivers must be installed on the data host before you
can set up a data host. The Sun StorageTek 2500 Series Array Release Notes lists the
data host requirements for HBAs and drivers. Get the release notes at:
http://doc.sun.com/app/docs/prod/st2500.array#hic
Refer to the specific vendor HBA documentation for instructions on installing HBA
drivers.
Multipathing
Data host software controls the data path between the data host and the storage
array. If there is more than one path between the host and the storage array for
redundancy, this function is called multipathing.
Install data host software (including multipathing) on each data host that
communicates with the Sun StorageTek 2500 Series Array. The multipathing
software you need depends on the host platform, HBA, and the data transport (SAS,
FC, or iSCSI) in your storage area network. This information is listed in the latest
version of the Sun StorageTek 2500 Series Array Release Notes.
Setting Up a Data Host On a Solaris

Next Steps
After you have installed and enabled multipathing on the data hosts, configure IP
addressing on the controller modules as described in Chapter 9.
88
Sun StorageTek 2500 Series Array Hardware Installation Guide • May 2010
CHAPTER
9
Configuring IP Addressing
In order for there to be an out-of-band Ethernet connection between the local
management host and the controller modules, the management host and the
controllers must have valid IP addresses.
This chapter describes how to configure IP addressing on the local management host
and on the controller modules. It contains the following sections:
■
“About IP Addressing” on page 89
■
“Configuring the IP Address of the Controller Modules” on page 90
About IP Addressing
The Sun StorageTek 2500 Series Array is managed out-of-band by way of a standard
Ethernet connection between the controller modules and your management host.
Perform the following procedures to ensure that the local management host and the
controllers have valid IP addresses:
■
Configure IP addresses for the controller modules (see “Configuring the IP
Address of the Controller Modules” on page 90)
■
Configure an IP address for the management host (see the Sun StorageTek Common
Array Manager Software Installation Guide)
89
Configuring the IP Address of the
Controller Modules
You can configure two types of IP addressing for the Ethernet port of each controller:
■
Dynamic Host Configuration Protocol (DHCP) IP addressing – IP addresses for
the Ethernet port are assigned dynamically from a DHCP server running
bootstrap protocol (BOOTP) services. An IP address assigned to an Ethernet port
is held only as long as needed. By default, DHCP is enabled at initial power-on.
■
Static IP Addressing – You assign a specific IP address to the Ethernet port of each
controller. Static IP addresses remain in effect until you modify or remove them or
you change the method of IP addressing for the Ethernet port to DHCP.
By default, if the controllers cannot find a DHCP server upon initial power-on, an
internal IP address is assigned to Ethernet port 1 of each controller:
■
The Ethernet port of Controller A is assigned IP address 192.168.128.101
■
The Ethernet port of Controller B is assigned IP address 192.168.128.102
■
The default subnet mask for each port is 255.255.255.0
To configure the Ethernet port on a controller with either dynamic or static IP
addressing, see one of the following sections:
■
“Configuring Dynamic (DHCP) IP Addressing” on page 90
■
“Configuring Static IP Addressing” on page 91
Configuring Dynamic (DHCP) IP Addressing
If BOOTP services are available on the DHCP server at initial power on of the
storage array, this server assigns a dynamic IP address for the Ethernet port on each
controller.
If a DHCP server is not available, the controller tray defaults to internal static IP
addresses as described in “Configuring the IP Address of the Controller Modules”
on page 90.
If you want to set up a DHCP server, refer to Appendix F for a description of how to
configure BOOTP services in Sun Solaris or Microsoft Windows environments.
You can restore DHCP IP addressing to Ethernet port 1 of either controller in either
of three ways:
90
■
Start a DHCP server on the same subnet, then reboot the 2500 Series Array.
■
Using the serial port interface (see “Using the Serial Port Interface to Assign IP
Addresses” on page 91).
Sun StorageTek 2500 Series Array Hardware Installation Guide • May 2010
■
Using the Sun StorageTek Common Array Manager (see the Sun StorageTek
Common Array Manager Software Installation Guide).
Configuring Static IP Addressing
There are two methods of assigning static IP addresses to the Ethernet ports of a
controller:
■
The serial port interface (see “Using the Serial Port Interface to Assign IP
Addresses” on page 91)
■
The Common Array Manager (see the Sun StorageTek Common Array Manager
Software Installation Guide).
Using the Serial Port Interface to Assign IP Addresses
You can use the serial port interface on a controller to set the IP address for the
Ethernet port on the controller.
To use the serial port interface to configure IP addressing for the Ethernet port of
each controller, you must complete the tasks described in the following sections:
■
“To Connect a Terminal to the Serial Port” on page 91
■
“To Set Up the Terminal Emulation Program” on page 92
■
“To Establish a Connection With the Serial Port” on page 93
■
“To Configure the IP Addresses” on page 94
To Connect a Terminal to the Serial Port
You will establish a serial connection to each controller, Controller A and Controller
B. One mini-DIN to RJ45 serial port cables are supplied with each controller tray.
To connect a terminal to the serial port of a controller:
1. Connect the 6-pin mini-DIN connector of the serial cable to the serial port on
the controller (“Controller Tray Rear-Access Components” on page 8).
2. Connect the RJ-45 connector of the serial cable to the serial port on the
terminal. It may be necessary to use the RJ45-DB9 adapter between the serial
cable RJ-45 connector and the serial port of the terminal.
3. For PC and laptop serial connections, you will also need to use a null modem.
Connect the RJ45-DB9 null modem adapter between the serial cable RJ-45
connector and the PC serial port.

Configuring iSCSI Overview
The following overview lists the major steps to configure the data host and target
storage after setting up the array and installing the management software.
For the full procedure go to “Configuring iSCSI - Detailed” on page 99
1. Configure an iSCSI port for each controller on the storage array.
2. On the data host:
a. Note its iSCSI Qualified Name (IQN) of the host.
b. Configure static discovery of the target ports.
3. In the Sun StorageTek Common Array Manager software:
a. Configure an initiator with the data host IQN.
97
b. Create a volume
c. Map the volume to the initiator through the host or host group.
4. On the data host:
a. Link the initiator and target volume, if needed.
b. Verify that you see the created volume.
5. Use system administration commands in the OS to mount/read/write to the
volume.
iSCSI Concepts
Configuring iSCSI requires an understanding of the following concepts.
■
iSCSI target - a storage device accessed over an Ethernet connection while still
using the SCSI infrastructure. One iSCSI target is supported per array. The Target
Details page appears in the software when supporting a Sun StorageTek 2510
array.
■
iSCSI session - consists of up to four connections between an iSCSI initiator and
the iSCSI target. The iSCSI initiator and target send and receive data over an
Ethernet connection while still using the SCSI protocol. Across all connections
within a session, an initiator sees one and the same target. Multiple initiators may
be connected to the iSCSI Target.
■
Authentication - Communication between the initiator and the target array can be
protected using CHAP authentication.
■
iSCSI ports - used for communication between the iSCSI initiator and the iSCSI
target. The storage array supports two iSCSI ports per controller, for a total of four
iSCSI ports per array.
■
Ethernet Network Interface Card (NIC) - you connect an Ethernet data path from
the data host to the storage using a NIC on the host side.
A NIC is an input/output (I/O) adapter that connects a host to a computer
network. The host central processing unit (CPU) must process the Small Computer
System Interface (SCSI) information in Ethernet frames.
Ethernet NICs require a software initiator. The iSCSI initiator runs on the data host
and converts SCSI commands into iSCSI commands to send and receive data over
the Ethernet connection to a target storage system. iSCSI initiators are operating
system specific. Examples are provided for configuring initiators in Solaris and
Windows. Consult your operating system documentation for Linux.

Adding Initiator Information
After creating an initiator on a data host, you need to add information about the
initiator to the management software.
Selecting Create New Initiator launches a wizard.
Add the following information:
■
Initiator Name - can be up to 30 characters. Valid characters are 'A-Z', 'a-z', '0-9',
hyphen('-') and underscore('_').
■
Unique Identifier - enter the IQN of the iSCSI initiators found on the data host
(See Step 2A on page 95). The identifier is used like a WWN in FC storage.
(The identifier can also be in EUI or NAA format. See the online help for the
syntax of these formats.)
IQN syntax example: iqn.2001-04.com.example:storage:diskarrays-sna8675309:
■
104
■
iqn - specifies the type of address
■
2001-04 - the date in yyyy-mm format
■
com.example:storage - the naming authority
■
diskarrays-sn-a8675309 - is the string defined by the naming authority.
Host type - specifies the OS and failover method of the data host.
Sun StorageTek 2500 Series Array Hardware Installation Guide • May 2010
■
Initiator's Host - select from a list of existing hosts or create a new one.
The wizard will allow you to assign the initiator to a host or host group. You use the
host or host group to map the initiator to a volume.
■
Authentication - enable Challenge-Handshake Authentication Protocol (CHAP)
authentication, if needed. (The example does not enable this). Enter a unique
password consisting of 12 to 57 alphanumeric characters.
You will also have to enter a CHAP secret on the Target Details page.
For more information about authentication, go to“Configuring Mutual
Authentication for an iSCSI Session” on page 106 for reference the online help.

Configuring Mutual Authentication for an iSCSI
Session
In a secure environment, authentication is not required because only trusted
initiators can access the targets.
In a less secure environment, the target cannot determine if a connection request is
truly from a given host. In that case, the target can authenticate an initiator by using
the Challenge-Handshake Authentication Protocol (CHAP).
CHAP authentication uses the notion of a challenge and response, which means that
the target challenges the initiator to prove its identity. For the challenge/response
method to work, the target must know the initiator's secret key and the initiator must
be set up to respond to a challenge.
You can configure mutual authentication for an iSCSI session so that both the iSCSI
initiator and iSCSI target use a CHAP secret.
For security purposes, Sun Microsystems recommends that the initiator and CHAP
secrets be unique.
You can add CHAP secrets when creating an initiator or add it later to an initiator
and target.
To Configure Mutual Authentication
1. Click Sun StorageTek Common Array Manager.
The navigation pane and the Storage System Summary page are displayed.
2. In the navigation pane, expand the storage array you want to work with.

required between the DC power source and the tray for over-current and shortcircuit protection. Before turning off any power switches on a DC-powered CRU or
module, you must disconnect the two-pole 20-amp circuit breaker.
Caution – Ensure that you do not turn on power to the controller tray or the
connected drive expansion trays until this guide instructs you to do so. For the
proper procedure for turning on the power, see “Connecting Power Cables” on
page 135.”
Caution – Electrical grounding hazard – This equipment is designed to permit the
connection of the D.C. supply circuit to the earthing conductor at the equipment.
Connecting the Cables
1. Disconnect the two-pole 20-amp DC circuit breaker for the storage array.
2. Ensure that all DC power switches on the DC-powered controller tray and all
DC power switches on any connected, DC-powered drive expansion trays are
turned off.
3. Connect the DC power connector cable to the DC power connector on each
power-fan assembly on the back of the controller tray.
Caution – The three source wires on the DC power connector cable (–48 VDC)
connect the trays to centralized DC power plant equipment, typically through a bus
bar located above the cabinet.
4. A qualified service person is required to make the DC power connection per
NEC and CEC guidelines. A two-pole 20-amp circuit breaker is required
between the DC power source and DC-powered trays for over-current and shortcircuit protection. Connect the DC power source wires on the other end of the
DC power connector cable to the centralized DC power plant equipment as
follows (see “DC Power Connector Cable and Source Wires” on page 132).
a. Connect the brown –48-VDC supply wire to the negative terminal.

b. Connect the blue return wire to the positive terminal.
c. Connect the green/yellow ground wire to the ground terminal.
5. If applicable, connect a DC power cable to each power-fan assembly on each
DC-powered drive expansion tray in the storage array.
Turning Off the DC Power During an Emergency
Caution – Potential loss of data – An emergency shutdown of the storage array
might not allow the server to complete its I/O to the storage array.
Note – Before turning off the power switches on a DC-powered tray you must
disconnect the two-pole 20-amp circuit breaker.
Relocation Cautions
Use the following guidelines when relocating trays or drives from one storage array
to another.
Caution – Potential data loss – Moving a storage array or array components that are
configured as part of a volume group can result in data loss. To prevent data loss,
always consult a Customer Support representative before relocating configured
drives, controller trays, or drive expansion trays.
Note – Trays in storage arrays can be connected to the DC power supply (–48 VDC).
Before turning off any power switches on a DC-powered tray, you must disconnect
the two-pole 20-amp circuit breaker.
Do not move controller trays or drive expansion trays that are part of a volume
group configuration. If you must move array components, contact a Customer
Support representative for procedures. A Customer Support representative might
direct you to complete several tasks prior to undertaking the relocation. These tasks
might include:
136
■
Creating, saving, and printing an array profile of each storage array that is
affected by the relocation of a drive or tray.
■
Performing a complete backup of all data on the drives that you intend to move.

Setting Up a Windows 2000 Advanced
Server
Before you begin, make sure the following requirements are met:
■
Windows 2000 server and the storage array are both on the same subnet.
■
IP addresses that are assigned to the controllers do not conflict.
■
The array is in BOOTP IP addressing mode (the default setting for a new array).
■
The Windows 2000 Server setup CD is available.
The following procedure provides an example of how to set up DHCP with the
BOOTP option on the Windows 2000 Advanced Server. Your environment might
require different steps.
Installing the DHCP Server
To install DHCP server on the Windows 2000 Advanced Server:
1. From the Control Panel, go to Administrative Tools >> Configure Your Server.
2. Select DHCP from the Networking drop-down menu on the left.
The wizard instructs you to use the Windows Components wizard to add the
DHCP component.
3. Start the Windows Components wizard and double-click Networking Services.
4. Select Dynamic Host Configuration Protocol (DHCP), click the check box to its
left, and click OK.
The Windows Components wizard is displayed.
5. Click Next.
6. If Terminal Services Setup is displayed, select Remote administration mode.
Click Next.
If your server has obtained an address from a DHCP server for its own address, a
warning is displayed.
7. Click OK to accept the warning.
Local Area Connection Properties is displayed.
8. Assign a static IP address to the server, or click Server to keep DHCP addressing
for the server. Click OK.

9. Click Finish to exit the Windows Components wizard.
The DHCP server is now installed. The next step is to configure the server.
Configuring the DHCP Server
To configure the DHCP server:
1. From the Control Panel, go to Administrative Tools >> Computer Management
>> Services and Application >> DHCP.
2. From the Action menu, select New Scope.
The New Scope wizard is displayed.
3. Enter the following information as prompted:
■
Scope name and description:
■
IP address range (for example, 192.168.0.170 to 192.168.0.171)
■
Subnet mask (for example, 255.255.255.0)
■
Add exclusions (do not exclude any IP addresses)
■
Lease duration (accept the default of 8 days)
■
Router (default gateway) of your subnet (for example, 192.168.0.1)
■
Domain name, WINS server (these are not needed)
■
Activate Scope? (select “Yes, I want to activate this scope now”)
4. Click Finish to exit the wizard.
The contents of the DHCP server are listed.
5. Right-click Scope [ipaddress] scope-name and select Properties.
6. In the Scope Properties box, click the Advanced tab.
7. Select BOOTP only, set the lease duration to Unlimited, and click OK.
8. Right-click Reservations.
The Controller A Properties box is displayed.
9. Enter the IP address and the MAC address for Controller A. Click Add.
The Controller B Properties box is displayed.
10. Enter the IP address and the MAC address for Controller B. Click Add.
The controllers are added to the right of the Reservations listing.
11. Right-click Scope [ipaddress] scope-name to disable the scope.
12. Click Yes to confirm disabling of the scope.
146
Sun StorageTek 2500 Series Array Hardware Installation Guide • May 2010
13. Right-click Scope and select Activate.
The DHCP server is now configured with the BOOTP option for the array
network.
14. Power on or power cycle the array modules.
15. Click Address Leases in the left pane to check the DHCP server leases.
The lease expiration displays the following status for each controller:
Reservation (active)
If the lease expiration for the controllers is inactive, try refreshing the list. If the lease
is still inactive, check the following:
■
Are the IP addresses allocated for BOOTP conflicting?
■
Were the correct MAC addresses added to the DHCP server for the controllers?
■
Are the DHCP server and storage array on the same subnet?
■
Is the gateway configured correctly on the DHCP server?
The controllers can gain a lease and an IP address, but they cannot respond out of
the subnet for the software if the gateway is not configured properly.
■
Are the controllers set up for BOOTP access?
It is possible that they were previously configured to have static IP addresses. You
must be sure when you move an array that you change the array’s IP addresses to
IP addresses on the new subnet before setting up BOOTP services.

pools, and virtual disks. Capacity planning should include allocations for volume
snapshots and volume copies.
CLI
Command-line interface. The SSCS command-line interface is available from the
remote CLI client or through an SSCS directory on the Solaris Operating System
management software station.

Series array, 1x1, 1x2, 1x3, and 1x4 array types are available.
control path
The route used for communication of system management information, usually an
out-of-band connection.
customer LAN
See site LAN.
DAS
See direct attached storage (DAS).
data host
Any host that uses the system for storage. A data host can be connected directly to
the array (direct attach storage, or DAS) or can be connected to an external switch
that supports multiple data hosts (storage area network, or SAN). See also host.
data path
The route taken by a data packet between a data host and the storage device.
direct attached storage (DAS)
A storage architecture in which one or two hosts that access data are connected
physically to a storage array.

150
Sun StorageTek 2500 Series Array Hardware Installation Guide • May 2010
expansion tray
A tray that does not have a RAID controller, used to expand the capacity of an array.
This type of tray must be attached to a controller tray to function.
extent
A set of contiguous blocks with consecutive logical addresses on a physical or virtual
disk.
failover and recovery
The process of changing the data path automatically to an alternate path.
fault coverage
The percentage of faults detected against all possible faults or against all faults of a
given type.
FC
See Fibre Channel (FC).
Fibre Channel (FC)
A set of standards for a serial I/O bus capable of transferring data between two ports
at up to 100 megabytes/second, with standards proposals to go to higher speeds.
Fibre Channel supports point to point, arbitrated loop, and switched topologies.
Fibre Channel was completely developed through industry cooperation, unlike SCSI,
which was developed by a vendor and submitted for standardization after the fact.
Fibre Channel switch
A networking device that can send packets directly to a port associated with a given
network address in a Fibre Channel storage area network (SAN). Fibre Channel
switches are used to expand the number of servers that can connect to a particular
storage port. Each switch is managed by its own management software.
field-replaceable unit (FRU)
An assembly component that is designed to be replaced on site, without the system
having to be returned to the manufacturer for repair.
FRU
See field-replaceable unit (FRU).
HBA
See host bus adapter (HBA).
151
host
As a function of the Sun StorageTek 2500 Series array configuration, a representation
of a data host that is mapped to initiators and volumes to create a storage domain.
See also data host, initiator.
host bus adapter (HBA)
An I/O adapter that connects a host I/O bus to a computer’s memory system.
Abbreviated HBA. Host bus adapter is the preferred term in SCSI contexts. Adapter
and NIC are the preferred terms in Fibre Channel contexts. The term NIC is used in
networking contexts such as Ethernet and token ring. See also initiator.
host group
A group of hosts with common storage characteristics that can be mapped to
volumes. See also host.
hot-spare
The drive used by a controller to replace a failed disk. See also array hot-spare.
in-band traffic
System management traffic that uses the data path between a host and a storage
device. See also out-of-band traffic.
initiator
A system component that initiates an I/O operation over a Fibre Channel (FC) or iSCSI
Ethernet network. If so configured, each host connection within the network has the
ability to initiate transactions with the storage array. Each host in the network represents
a separate initiator, so if a host is connected to the system through two host bus adapters
(HBAs) or NICs, the system identifies two different initiators (similar to multi-homed,
Ethernet-based hosts). In contrast, when multipathing is used in round-robin mode,
multiple HBAs or NICs are grouped together, and the multipathing software identifies
the group as a single initiator.
IOPS
A measure of transaction speed, representing the number of input and output
transactions per second.
iSCSI
iSCSI is an acronym for internet SCSI (Small Computer System Interface). This
storage networking standard transports block level data and SCSI commands as IP
packets over Ethernet as described in RFC 3720.
LAN
Local area network.
152
Sun StorageTek 2500 Series Array Hardware Installation Guide • May 2010
logical unit number (LUN)
The SCSI identifier for a volume as it is recognized by a particular host. The same
volume can be represented by a different LUN to a different host.
LUN
See logical unit number (LUN).
MAC address
See media access control (MAC) address.
management host
A Solaris host serving the configuration, management, and monitoring software for
the Sun StorageTek 2500 Series array. The software on the station can be accessed
with a browser to run the browser interface or with a remote scripting command-line
interface (CLI) client to access the SSCS CLI commands.
master / alternate master
A design for reliability that uses redundant configuration. Array configurations share
master/alternate master configurations: each array configuration has two controller
trays that are grouped as one host. In each case, the master component uses the IP
address and name. If the master fails, the alternate master assumes the IP address
and name and takes over the master’s functions.
media access control (MAC) address
The physical address identifying an Ethernet controller board. The MAC address,
also called an Ethernet address, is set at the factory and must be mapped to the IP
address of the device.
mirroring
A form of storage – also called RAID Level 1, independent copy, and real-time copy –
whereby two or more independent, identical copies of data are maintained on separate
media. Typical mirroring technologies enable the cloning of data sets to provide
redundancy for a storage system.
multipathing
A design for redundancy that provides at least two physical paths to a target.
out-of-band traffic
System management traffic outside of the primary data path that uses an Ethernet
network. See also in-band traffic.
PDU
See power distribution unit (PDU).
153
pool
See storage pool.
power distribution unit (PDU)
The assembly that provides power management for the system. The redundant
design uses two PDUs in each system so that the system’s data path continues to
function if one of the PDUs fails.
profile
See storage profile.
provisioning
The process of allocation and assignment of storage to hosts.
RAID
An acronym for Redundant Array of Independent Disks, a family of techniques for
managing multiple disks to deliver desirable cost, data availability, and performance
characteristics to host environments. Also, a phrase adopted from the 1988 SIGMOD
paper A Case for Redundant Arrays of Inexpensive Disks.
remote monitoring
Monitoring of the functions and performance of a hardware system from a location
other than where the hardware resides.
remote scripting CLI client
A command-line interface (CLI) that enables you to manage the system from a remote
management host. The client communicates with the management software through a
secure out-of-band interface, HTTPS, and provides the same control and monitoring
capability as the browser interface. The client must be installed on a host that has network
access to the system.
SAN
See storage area network (SAN).
site LAN
The local area network at your site. When the system is connected to your LAN, the
system can be managed through a browser from any host on the LAN.
154
Sun StorageTek 2500 Series Array Hardware Installation Guide • May 2010
snapshot
An copy of a volume’s data at a specific point in time.
SSCS
Sun Storage Command System. The command-line interface (CLI) that can be used to
manage the array.
storage area network (SAN)
An architecture in which the storage elements are connected to each other and to a server
that is the access point for all systems that use the SAN to store data.
storage domain
A secure container that holds a subset of the system’s total storage resources. Multiple
storage domains can be created to securely partition the system’s total set of storage
resources. This enables you to organize multiple departments or applications into a single
storage management infrastructure.
storage pool
A container that groups physical disk capacity (abstracted as virtual disks in the
browser interface) into a logical pool of available storage capacity. A storage pool’s
characteristics are defined by a storage profile. You can create multiple storage pools
to segregate storage capacity for use in various types of applications (for example,
high throughput and online transaction-processing applications).
storage profile
A defined set of storage performance characteristics such as RAID level, segment size,
dedicated hot-spare, and virtualization strategy. You can choose a predefined profile
suitable for the application that is using the storage, or you can create a custom profile.
storage tray
An enclosure containing disks. A tray with dual RAID controllers is called a
controller tray; a tray without controllers is called an expansion tray.
stripe size
The number of blocks in a stripe. A striped array’s stripe size is the stripe depth
multiplied by the number of member extents. A parity RAID array’s stripe size is the
stripe depth multiplied by one less than the number of member extents. See also
striping.
striping
Short for data striping; also known as RAID Level 0 or RAID 0. A mapping technique in
which fixed-size consecutive ranges of virtual disk data addresses are mapped to
successive array members in a cyclic pattern. (SNIA).
155
target
The system component that receives a SCSI I/O command. (SNIA).
thin-scripting client
See remote scripting CLI client.
tray
See storage tray.
virtual disk
A set of disk blocks presented to an operating environment as a range of
consecutively numbered logical blocks with disk-like storage and I/O semantics. The
virtual disk is the disk array object that most closely resembles a physical disk from
the operating environment’s viewpoint.
volume
A logically contiguous range of storage blocks allocated from a single pool and presented
by a disk array as a logical unit number (LUN). A volume can span the physical devices
that constitute the array, or it can be wholly contained within a single physical disk,
depending on its virtualization strategy, size, and the internal array configuration. The
array controller makes these details transparent to applications running on the attached
server system.
volume snapshot
See snapshot.
WWN
World Wide Name. A unique 64-bit number assigned by a recognized naming
authority such as the Institute of Electrical and Electronics Engineers (IEEE) that
identifies a connection (device) or a set of connections to the network. The World
Wide Name (WWN) is constructed from the number that identifies the naming
authority, the number that identifies the manufacturer, and a unique number for the
specific connection.
