Switch LEDs and controls

The switch LEDs provide information about the switch’s operational status. These LEDS include the Input Power LED (green), Heartbeat LED (green), and the System Fault LED (amber) (Figure 2). For information about port LEDs, see ”Port LEDs” on page 15. The Maintenance button (Figure 2) is the only switch control. It is used to reset a switch or to recover a disabled switch. To apply power to the switch, plug the power cord into the switch AC power receptacle, located on the back of the switch, and into a 100–240 VAC power source.

Figure 2 Switch LEDs and controls

Input power LED (green)

The Input Power LED indicates the voltage status at the switch logic circuitry. During normal operation, this LED illuminates to indicate that the switch logic circuitry is receiving the proper DC voltages. When the switch is in maintenance mode, this LED is extinguished.

Heartbeat LED (green)

The Heartbeat LED indicates the status of the internal switch processor and the results of the POST. Following a normal power-up, the Heartbeat LED blinks about once per second to indicate that the switch passed the POST and that the internal switch processor is running. In maintenance mode, the Heartbeat LED illuminates continuously. For more information, see ”Heartbeat LED blink patterns” on page 52.

System fault LED (amber)

The System Fault LED illuminates to indicate that a fault exists in the switch firmware or hardware. Fault conditions include POST errors, over-temperature conditions, and power supply malfunctions. The Heartbeat LED shows a blink code for POST errors and over-temperature conditions. For more information, see ”Heartbeat LED blink patterns” on page 52.

Maintenance button

The Maintenance button (Figure 2) is a dual-function momentary switch on the front panel. Its purpose is to reset the switch or to place the switch in maintenance mode. Maintenance mode sets the IP address to

10.0.0.1 and provides access to the switch for maintenance purposes when flash memory or the resident configuration file is corrupted. For more information, see ”Recovering a switch using maintenance mode” on page 57.

Resetting a switch

To reset the switch, press and hold the Maintenance button with a pointed tool for less than 2 seconds. The switch will respond as follows:

1. All the switch LEDs will illuminate except the System Fault LED.

2. After approximately 1 minute, the power-on self test (POST) begins, extinguishing the Heartbeat LED.

3. When the POST is complete, the Input Power LED is illuminated and the Heartbeat LED is flashing once

per second.

Placing the switch in maintenance mode

To place the switch in maintenance mode:

1. Isolate the switch from the fabric.

2. Press and hold the Maintenance button with a pointed tool for a few seconds until only the Heartbeat

LED (Figure 2) is illuminated. Continue holding the maintenance button until the Heartbeat LED goes off, then release the button. The Heartbeat LED illuminates continuously while the switch is in maintenance mode.

To exit maintenance mode and return to normal operation, press and release the Maintenance button momentarily to reset the switch.

The HP StorageWorks SN6000 Fibre Channel Switch has 20 Fibre Channel Small Form-Factor Pluggable (SFP) ports and four Fibre Channel XPAK ports. SFP ports are numbered 0–19 (Figure 3). Each SFP port is served by an SFP optical transceiver and is capable of 1, 2, 4, or 8 Gb/s transmission. SFP ports are hot-pluggable and can self-discover both the port type and transmission speed when connected to devices or other switches. The port LEDs are located above ports 0–9 and below ports 10–19, and provide port login and activity status information.

The XPAK ports are numbered 20–23 (Figure 3). Each XPAK port is served by an XPAK optical transceiver or an XPAK switch stacking cable. An XPAK port is capable of 10 Gb/s (actual data transmission bandwidth 12.75 Gb/s) or 20 Gb/s (actual data transmission bandwidth 25.5 Gb/s) with the optional license key. XPAK ports are hot-pluggable and can self-discover transmission speed when connected to other switches. The XPAK switch stacking cable is a passive cable and transceiver assembly for connecting to other XPAK-capable switches. The XPAK ports come with covers that must be removed before installing transceivers or cables. XPAK port LEDs are located to the left of their respective ports and provide port login and activity status.

NOTE: Setting a Fibre Channel port that has an 8 Gb/s SFP transceiver to 1 Gb/s downs the port.

License keys are available from your authorized reseller to upgrade the XPAK ports to 20 Gb/s. For more information, see ”Installing feature license keys” on page 46.

Port LEDs

Each port has its own Logged-in LED (green) and Activity LED (green) (Figure 4).

1 Logged-in LED (port 9) 2 Activity LED (port 9) 3 Activity LED (port 23) 4 Logged-in LED (port 23)

Figure 4 Port LEDs

Port Logged-in LED (green)

The Logged-in LED indicates the logged-in or initialization status of the connected devices. After successful completion of the POST, the switch extinguishes all Logged-in LEDs. Following a successful port login, the switch illuminates the corresponding logged-in LED. This shows that the port is properly connected and able to communicate with its attached devices. The Logged-in LED remains illuminated as long as the port is initialized or logged in. If the port connection is broken or an error occurs that disables the port, the Logged-in LED is extinguished. For more information, see ”Logged-in LED indications” on page 54.

Port Activity LED (green)

The Activity LED indicates that data is passing through the port. Each frame that the port transmits or receives illuminates this LED for 50 milliseconds. This makes it possible to observe the transmission of a single frame.

Transceivers

The HP StorageWorks SN6000 Fibre Channel Switch supports SFP optical transceivers for the SFP ports and XPAK optical transceivers or XPAK stacking cables for the XPAK ports. A transceiver converts electrical signals to and from optical laser signals to transmit and receive data. Duplex fiber optic cables plug into the SFP transceivers which then connect to the devices. An SFP port is capable of transmitting at 1-, 2-, 4-, or 8-Gb/s; however, the transceiver must also be capable of delivering at these rates.

The SFP and XPAK transceivers are hot-pluggable. This means that you can remove or install a transceiver while the switch is operating without harming the switch or the transceiver. However, communication with the connected device is interrupted. For information about installing and removing SFP+ optical transceivers, see ”Install the transceivers” on page 39.

Port types

The SN6000 Fibre Channel Switch supports generic ports (G_Port, GL_Port), fabric ports (F_Port, FL_Port), expansion ports (E_Port), and transparent routing ports (TR_Port). Switches come from the factory with all

HP StorageWorks SN6000 Fibre Channel Switch Installation and Reference Guide 15

SFP ports configured as GL_Ports and all XPAK ports configured as G_Ports. Table 2 describes generic, fabric, expansion, and transparent routing port functions.

Table 2 Fibre Channel port types

Port type Description

GL_Port Generic loop port—self-configures as an FL_Port when connected to a

loop device, as an F_Port when connected to a single device, or as an E_Port when connected to another switch. If the device is a single device on a loop, the GL_Port will attempt to configure first as an F_Port, then if that fails, as an FL_Port.

G_Port Generic port—self-configures as an F_Port when connected to a single

device, or as an E_Port when connected to another switch.

FL_Port Fabric loop port—supports a loop of up to 126 devices. An FL_Port can

also configure itself during the fabric login process as an F_Port when connected to a single device (N_Port).

F_Port Fabric port—supports a single device.

E_Port Expansion port—expands the fabric by connecting SN6000 or 8/20q

Fibre Channel switches. The SN6000 Fibre Channel Switch self-discovers all inter-switch connections. For more information, see ”Multiple switch

fabrics” on page 23.

TR_Port Transparent routing port—expands the fabric by connecting an SN6000

Fibre Channel Switch to an HP StorageWorks B-series or C-series remote fabric. The TR_Port provides transparent communication between local fabric devices and remote fabric devices while maintaining separate fabrics. For more information, see ”Transparent routing” on page 26.

Ethernet port

The Ethernet port is an RJ-45 connector that provides a connection to a workstation through a 10/100 Base-T Ethernet cable (Figure 5). A workstation can be a Windows configure and manage the switch fabric. An Ethernet connection to the switch is required to manage the switch using the CLI, QuickTools, Simple SAN Connection Manager, or Simple Network Management Protocol (SNMP).

The Ethernet port has two LEDs: the Link Status LED (green) and the Activity LED (green). The Link Status LED illuminates continuously when an Ethernet connection has been established. The Activity LED illuminates when data is being transmitted or received over the Ethernet connection.

Serial port

The SN6000 Fibre Channel Switch is equipped with an RS-232 serial port for maintenance purposes (Figure 6). You can manage the switch through the serial port using the CLI.

Power supplies and fans

The SN6000 Fibre Channel Switch - Single Power Supply has a single power supply that converts 100–240 VAC to DC voltages for the various switch circuits. Internal fans provide cooling. The switch monitors internal air temperature, and therefore does not monitor or report fan operational status. Air flow is front-to-back. To energize the switch, plug the power cord into the switch AC receptacle and into a 100–240 VAC power source.

The SN6000 Fibre Channel Switch - Dual Power Supply has two hot-pluggable power supplies that convert standard 100–240 VAC to DC voltages for the various switch circuits. Each power supply has an AC power receptacle and two status LEDs (Figure 7):

• The Power Supply Status LED (green) illuminates to indicate that the power supply is receiving AC

voltage and producing the proper DC voltages.

• The Power Supply Fault LED (amber) illuminates to indicate that a power supply fault exists and requires

attention.

1 Power supply 1 2 Power supply 2

3 Status LED (green) 4 Fault LED (amber)

5 AC power receptacle

Figure 7 SN6000 Power Supplies

Each power supply is capable of providing all of the switch’s power needs. During normal operation, each power supply provides half of the demand. If one power supply goes offline, the second power supply steps up and provides the difference.

The power supplies are hot-pluggable and interchangeable. Hot-pluggable means that you can remove and replace one power supply while the switch is in operation without disrupting service. See ”Transceiver

Removal and Replacement” on page 61 for information about replacing the power supplies.

Connecting a power supply to an AC voltage source energizes the switch logic circuitry. Internal fans provide cooling. Air flow is front-to-back.

Switch management

The switch supports the following management tools and protocols:

• QuickTools web applet, page 19

• Simple SAN Connection Manager, page 19

• Command line interface, page 19

• Simple Network Management Protocol, page 20

• Storage Management Initiative–Specification (SMI-S), page 20

Simple SAN Connection Manager

HP StorageWorks Simple SAN Connection Manager is a GUI-based management application for HP StorageWorks that runs on a workstation known as the management station. It provides basic automated configuration and management of switches, HBAs, and storage devices.Simple SAN Connection Manager version 3.0 or later is required for the HP SN6000 Fibre Channel Switch.

Command line interface

The command line interface (CLI) provides monitoring and configuration functions by which the administrator can manage the fabric and its switches. The CLI is available over an Ethernet connection or a serial connection. For more information, see the HP StorageWorks SN6000 Fibre Channel Switch Command Line Interface Guide.

HP StorageWorks SN6000 Fibre Channel Switch Installation and Reference Guide 19

Simple Network Management Protocol

SNMP provides monitoring and trap functions for the fabric. The switch firmware supports SNMP versions 1, 2, and 3, the Fibre Alliance Management Information Base (FA-MIB) version 4.0, and the Fabric Element Management Information Base (FE-MIB) RFC 2837. Traps can be formatted using SNMP version 1 or 2. SNMP version 3 provides secure access to devices through a combination of authentication and encryption. You can enable SNMP, configure SNMP traps, and configure SNMP version 3 security using the command line interface or QuickTools.

Storage Management Initiative–Specification (SMI-S)

SMI-S provides for the management of the switch through third-party applications that use the SMI-S. For more information, see the HP StorageWorks 8/20q and SN6000 Fibre Channel Switch CIM Agent Reference Guide.

File transfer protocols

FTP and TFTP provide the command line interface for exchanging files between the switch and the workstation. These files include firmware image files, configuration files, and log files. For more information about FTP and TFTP, see the HP StorageWorks SN6000 Fibre Channel Switch Command Line Interface Guide.

2 Planning

Consider the following when planning a fabric:

• Devices, page 21

• Device access, page 21

• Performance, page 22

• Feature licenses, page 23

• Multiple switch fabrics, page 23

• Switch services, page 28

• Security, page 30

• Fabric management, page 32

Devices

When planning a fabric, consider the following:

• The number of devices and the anticipated demand. This will determine the number of ports that are

needed and in turn the number of switches.

• The transmission speeds of your HBAs, SFPs, and XPAKs. The switch supports 2 Gb/s, 4 Gb/s and 8

Gb/s transmission speeds with SFPs. The transmission speed for XPAKs is 10 Gb/s or 20 Gb/s when enabled by installation of the SN6000 Stackable 20Gb ISL Upgrade LTU.

IMPORTANT: Setting a Fibre Channel port that has an 8 Gb/s SFP transceiver to 1 Gb/s downs the port.

• The distribution of targets and initiators. An F_Port supports a single device. An FL_Port can support up

to 126 devices in an arbitrated loop.

Device access

Consider device access needs within the fabric. Access is controlled by the use of zoning. Some zoning strategies include the following:

• Separating devices by operating system

• Separating devices that have no need to communicate with other devices in the fabric or have

classified data

• Separating devices into department, administrative, or other functional group

Zoning divides the fabric for purposes of controlling discovery and inbound traffic. A zone is a named group of ports or devices. Members of the same zone can communicate with each other and transmit outside the zone, but cannot receive inbound traffic from outside the zone. Zoning is hardware-enforced only when a port/device is a member of no more than eight zones whose combined membership does not exceed 64. If this condition is not satisfied, that port behaves as a soft zone member. You can assign ports/devices to a zone individually or as a group by creating an alias.

A zone can be a component of more than one zone set. Several zone sets can be defined for a fabric, but only one zone set can be active at one time. The active zone set determines the current fabric zoning.

HP StorageWorks SN6000 Fibre Channel Switch Installation and Reference Guide 21

A zoning database is maintained on each switch. Table 4 describes the zoning database limits, excluding the active zone set.

Table 4 Zoning database limits

(2,000), excluding the orphan zone set. Each instance of a zone in a zone set counts toward this maximum.

• Distance, page 22

• Bandwidth, page 22

• Latency, page 23

Distance

Consider the physical distribution of devices and switches in the fabric. Choose SFP transceivers that are compatible with the cable type, distance, Fibre Channel revision level, and the device host bus adapter. For more information about cable types and transceivers, see ”Technical specifications” on page 71.

Each Fibre Channel port is supported by a data buffer with a 16 credit capacity; that is, 16 maximum sized frames. For fibre optic cables, this enables full bandwidth over approximately 3 kilometers at 8 Gb/s (4.8 credits/km).

Bandwidth

Bandwidth is a measure of the volume of data that can be transmitted at a given transmission rate. An SFP port can transmit or receive at nominal rates of 1, 2, 4, or 8 Gb/s depending on the device to which it is connected. This corresponds to full duplex bandwidth values of 212 MB, 424 MB, 850 MB, and 1700 MB respectively. XPAK ports transmit at a nominal rate of 10 Gb/s which corresponds to a full duplex bandwidth value of 2550 MB. With an SN6000 Stackable 20Gb ISL Upgrade LTU, XPAK ports can transmit at a nominal rate of 20 Gb/s (5100 MB bandwidth)

Multiple source ports can transmit to the same destination port if the destination bandwidth is greater than or equal to the combined source bandwidth. For example, two 2 Gb/s source ports can transmit to one 4 Gb/s destination port. Similarly, one source port can feed multiple destination ports if the combined destination bandwidth is greater than or equal to the source bandwidth.

In multiple chassis fabrics, each link between chassis contributes 424, 850, 1700, 2550 or 5100 megabytes of bandwidth between those chassis, depending on the speed of the link. When additional bandwidth is needed between devices, increase the number of links between the connecting switches. The switch guarantees in-order delivery with any number of links between chassis.

Latency

Latency is a measure of how fast a frame travels through a switch from one port to another. The factors that affect latency include transmission rate and the source/destination port relationship (Table 5).

Feature licenses

A license key provides a way to expand the capabilities of your switch and fabric as your needs grow. The HP StorageWorks SN6000 Stackable 20Gb ISL Upgrade LTU enables the XPAK ports to transmit at 20 Gb/s instead of the default 10 Gb/s. Applying a license key is not disruptive, nor does it require a switch reset. To order a license key, contact your switch distributor or your authorized reseller. For more information, see ”Installing feature license keys” on page 46.

< 0.4 sec1 < 0.3 sec1

Multiple switch fabrics

By connecting switches to one another, you can expand the number of available ports for devices. Each switch in the fabric is identified by a unique domain ID, and the fabric can automatically resolve domain ID conflicts. Because the Fibre Channel ports are self-configuring, you can connect SN6000 Fibre Channel Switches together in a wide variety of topologies. When planning your fabric, consider your topology and cabling requirements. Transparent routing to a legacy fabric is also possible using TR_Ports.

For more information about Storage Area Network (SAN) connectivity, see the SAN Design Reference Guide available at the HP website: http://www.hp.com/go/SANdesignguide

The following topics describe important aspects of multiple switch fabrics:

• Optimizing device performance, page 23

• Domain ID, principal priority, and domain ID lock, page 24

• Common topologies, page 26

• Transparent routing, page 26

Optimizing device performance

When choosing a topology for a multiple switch fabric, you should also consider the proximity of your server and storage devices and the performance requirements of your application. Storage applications such as video distribution, medical record storage/retrieval, or real-time data acquisition can have specific latency or bandwidth requirements.

The SN6000 Fibre Channel Switch provides the lowest latency of any product in its class. For information about latency, see ”Performance” on page 22. However, the highest performance is achieved on Fibre Channel switches by keeping traffic within a single switch instead of relying on ISLs. Therefore, for optimal device performance, place devices on the same switch under the following conditions:

• Heavy I/O traffic between specific server and storage devices.

• Distinct speed mismatch between devices such as the following:

• An 8 Gb/s server and a slower 4 Gb/s storage device

• A high performance server and a slow tape storage device

HP StorageWorks SN6000 Fibre Channel Switch Installation and Reference Guide 23

Domain ID, principal priority, and domain ID lock

The following switch configuration settings affect multiple switch fabrics:

• Domain ID

• Principal priority

• Domain ID lock

The domain ID is a unique number from 1–239 that identifies each switch in a fabric. The principal priority is a number (1–255) that determines the principal switch which manages domain ID assignments for the fabric. The switch with the highest principal priority (1 is high, 255 is low) becomes the principal switch. If the principal priority is the same for all switches in a fabric, the switch with the lowest Worldwide Name (WWN) becomes the principal switch.

The domain ID lock allows (False) or prevents (True) the reassignment of the domain ID on that switch. Switches come from the factory with the domain ID set to 1, the domain ID lock set to False, and the principal priority set to 254. For information about changing the default domain ID, domain ID lock, and principal priority parameters, see the set config switch command in the HP StorageWorks SN6000 Fibre Channel Switch Command Line Interface Guide.

If you connect a new switch to an existing fabric with its domain ID unlocked, and a domain ID conflict occurs, the new switch will isolate as a separate fabric. You can remedy this by resetting the new switch or taking it offline then putting it back online. The principal switch will reassign the domain ID and the switch will join the fabric.

NOTE: Domain ID reassignment is not reflected in zoning that is defined by domain ID/port number pair

or Fibre Channel address. You must reconfigure zones that are affected by domain ID reassignment. To prevent zoning definitions from becoming invalid under these conditions, lock the domain IDs. Domain ID reassignment has no effect on zone members defined by WWN.

Stacking

You can connect up to six HP StorageWorks SN6000 Fibre Channel Switches together through the XPAK ports, thus preserving the SFP ports for devices. This is called stacking. The following 2-, 3-, 4-, 5-, and 6-switch stacking configurations are recommended for best performance and redundancy. Each XPAK port contributes 12.75 GB of bandwidth between chassis in each direction. This is equivalent to three SFP connections operating at 4 Gb/s. If you upgrade the XPAK ports to 20 Gb/s, this is equivalent to three SFP connections operating at 8 Gb/s. Figure 8 shows a two-switch stack of model SN6000 switches using two 3-inch XPAK switch stacking cables. 40 SFP ports are available for devices.

Figure 8 Two -switch sta ck

Figure 9 shows a three-switch stack of HP StorageWorks SN6000 Fibre Channel Switch switches using two

3-inch and one 9-inch XPAK switch stacking cables. 60 SFP ports are available for devices.

Figure 12 shows a six-switch stack of model SN6000 switches using eight XPAK switch stacking cables.

120 SFP ports are available for devices.

Figure 12 Six-switch stack

Common topologies

Although HP recommends using the XPAK stacking ports to achieve the highest cabling efficiency and bandwidth, you can also create multiple switch configurations using the SFP ports. The HP StorageWorks SN6000 Fibre Channel Switch switch supports the following topologies using the SFP ports:

• Cascaded fabric topology

• Ring fabric topology

• Meshed fabric topology

• Core-edge fabric topology

For additional information about topologies and Storage Area Network (SAN) connectivity, see the SAN Design Reference Guide available at the HP website: http://www.hp.com/go/SANdesignguide

Transparent routing

IMPORTANT: The Simple SAN Connection Manager (SSCM) application can manage SN6000 Fibre

Channel Switches with active TR_Ports; however, SSCM cannot manage or discover remote switches or devices in the remote fabric. Use QuickTools and the storage management interface to present Logical Unit Numbers (LUNs) to remote devices. SSCM displays the remote fabric as a grayed-out switch, and no management can be performed. SSCM version 3.0 or later is required for the HP SN6000 Fibre Channel Switch. SSCM version 2.0 and earlier versions do not support the management of fabrics that include switches with active TR_Ports and may disrupt communication between an SN6000 or 8/20q Fibre Channel Switch and the remote fabric.

The transparent routing feature provides inter-fabric routing to allow controlled and limited access between devices on a SN6000 Fibre Channel Switch (local) fabric and devices on a remote fabric consisting of B-series or C-series switches. For a list of switches that are supported in a remote fabric, see the HP

StorageWorks SN6000 Fibre Channel Switch Release Notes, and the HP StorageWorks SAN Design Reference Guide on the HP website: http://www.hp.com/go/sandesignguide

. This type of inter-fabric connection uses the Fibre Channel industry N-Port ID Virtualization (NPIV), and makes local and remote devices accessible to each other while maintaining the local and remote fabrics as separate fabrics.

You can connect multiple SN6000 Fibre Channel Switches to one or more remote fabrics using multiple TR_Ports. Local and remote devices are identified by their respective port worldwide names. Consider the following mapping rules:

• A TR_Port can support a maximum of 32 local device/remote device mappings.

• A specific local device can be mapped to devices on only one remote fabric. Local devices on the same

SN6000 Fibre Channel Switch can each be mapped to different remote fabrics.

• For mappings between a specific SN6000 Fibre Channel Switch and a remote fabric, each local

device or remote device can be mapped over only one TR_Port. Additional mappings to either device must use that same TR_Port.

• Multiple local devices connected to different local switches can be mapped to the same remote device

over one TR_Port on each local switch.

• A local device cannot be mapped over an E_Port to another local switch, then over a TR_Port to the

remote device. The local switch to which the local device is connected must connect directly to the remote fabric over a TR_Port.

NOTE: When a local device is mapped over a TR_Port to a remote device, the local device and its

TR_Port appear as an NPIV connected device in the remote fabric. It is possible, though not recommended, to map such a local device over a second TR_Port to a local device in a second local fabric. In this case, if you merge the two local fabrics, the transparent route becomes inactive for the devices that now have a path over an ISL, and an alarm is generated.

You can configure transparent routing using QuickTools or the CLI, though QuickTools is recommended because it validates your entries, manages the zone mapping for the local fabric, and creates a list of zoning commands that can be run in a script on a HP StorageWorks B-series or C-series SAN switch. For more detailed information, see the HP StorageWorks SN6000 Fibre Channel Switch QuickTools Switch

Management User Guide and the HP StorageWorks SN6000 Fibre Channel Switch Command Line Interface Guide.

IMPORTANT: Since C-series switches do not support the Unzoned Name Server, C-series fabrics must be

“pre-zoned” before you can set up TR mappings to a remote C-series fabric using the TR Mapping Manager dialog box. The C-series fabric zoneset must be changed to add zones so that the WWNs of the remote devices to be mapped and the WWNs of the SN6000 Fibre Channel Switch TR ports are zoned together. For more information, see the C-series documentation for specific information to configure zoning. Retain these zones in the zoneset after completion of the TR mapping as a best practice, until you no longer need to map the device to the local fabric.

To configure transparent routing using QuickTools:

1. Determine what devices on the local fabric require access to devices on the remote fabric. Local devices

must be attached directly to the SN6000 Fibre Channel Switch.

2. Configure one or more TR_Ports on the local SN6000 Fibre Channel Switch first and then connect the

TR_Port to the remote fabric. QuickTools prompts you to configure TR_Ports where existing port connections to remote fabrics have isolated. For remote HP StorageWorks B-series or C-series fabrics, the switch to which the TR_Port connects must support N-Port ID Virtualization (NPIV) and for B-series fabrics the interoperability mode must be configured to InteropMode=0. Other B-series or C-series switches in the remote fabric need not support NPIV.

NOTE: Be sure to configure the TR_Port before connecting the remote fabric to the HP

StorageWorks SN6000 Fibre Channel Switch. If the remote fabric is connected to a port on the HP StorageWorks SN6000 Fibre Channel Switch that is not a TR_Port, the two fabrics may establish an E_Port connection and the local and remote fabrics may merge. This mixed fabric is not a supported configuration. If the port type is changed to TR_Port after connecting the remote fabric, a port reset may be required to completely establish the TR connection.
