Installation

Before the MSA Fabric Switch 6 can communicate with Compaq-managed devices, all devices must be properly connected and powered on.

Ethernet RJ-45 Cable

This connector is provided for management through Simple Network Management Protocol (SNMP). By default, the MSA Fabric Switch 6 is configured to use an IP address of 127.0.0.1. To change this IP address, use ACU-XE, a terminal, or a terminal emulator connected to the DB-9 serial port. Refer to Chapter 2, ???Initial Configuration of the Switch,??? for more detailed information on this subject.

DB-9 Serial Cable

This connector is provided for advanced configuration and management.

The MSA Fabric Switch 6 is designed to function directly out of its shipping container with no special configuration required. However, you have the ability to configure and monitor various aspects of the MSA Fabric Switch 6 by using ACU-XE or CIM-XE or by connecting a terminal or terminal emulator to the serial port. See Chapter 2, ???Initial Configuration of the Switch,??? for more information on using this interface.

Overview of the Switch

Hot-Pluggable

The MSA Fabric Switch 6 is hot-pluggable. The unit can be installed and replaced without power-cycling the MSA1000.

When adding or replacing a switch, allow sufficient time to complete the power-on self-tests (POST) and configuration tasks before using.

To power on the unit properly:

1.Power on the MSA1000.

On power up, the switch will run several POST tests and the GSI indicator will display changing patterns (refer to the section ???Reading the Global Service Indicator??? in Chapter 4, ???Troubleshooting???).

2.Power on I/O device(s).

3.Verify that the storage device(s) are visible to the host(s).

4.Start Applications.

Before the MSA Fabric Switch 6 can communicate with Compaq-managed devices, all devices must be properly configured, connected, and powered up. See Chapter 2, ???Initial Configuration of the Switch,??? for installation instructions.

Setting up Zoning

Zoning is a function of the MSA Fabric Switch 6 that allows you to create isolated Fibre Channel networks with a limited number of connected devices. By limiting the number of devices in a zone, you can obtain more robust performance and enhance access protection.

Zoning is compliant with the following standards:

???FC-SW-2

???FC-GS3

???FC-MI

MSA Fabric Switch 6 Management Utility

This section describes the zoning functions supported by the MSA Fabric Switch 6. It describes zoning at the individual switch and describes how the merge command functions are used to support zoning across a Fabric.

Zoning Elements

Before setting up zoning, you must understand the following zoning elements:

???Zone Members

???Zones

???Zone Sets

CAUTION: Never add a zoned switch to an established fabric that has no zoning. If a switch configured with zoning is added to a fabric that has no configured zoning, the fabric???s HBAs and targets will no longer be able to communicate and the traffic in the fabric will be disrupted. For best results, only add a switch configured with zoning to a fabric configured with the same zoning configuration.

Zone Members

Zone members are Fibre Channel edge devices that are identified by their World Wide Port Name (WWPN). Any device that you want to include in a zone must be identified as a zone member. While internally the zone members are tracked by their WWPN, you can create a Zone Member Name that acts as an alias for the device. This makes it easier to identify the devices during configuration and operation. The following are examples of Fibre Channel devices that can be named as zone members:

???Servers

???Raid systems

???Disk drives

???Tape libraries

IMPORTANT: The World Wide Node Name (WWNN) of the Fibre Channel device cannot be used to create a zone member. WWNN-bases zoning is expressly prohibited in the FC-MI standard. Use World Wide Port Name (WWPN) to create a zone member.

MSA Fabric Switch 6 Management Utility

Zones

Zones are logical entities that represent groupings of zone members. Each zone must be assigned a unique zone name when it is defined.

Zone Sets

Zone sets are logical entities that represent groupings of zones. They define a zoning configuration. Each zone set is assigned a unique zone set name when it is defined. The MSA Fabric Switch 6 allows storing of multiple zone sets. However, only one of these zone sets can be active at a time. The other zone sets can be used as backup, trials, or other user-defined configurations.

Naming Rules for Zone Members, Zones, and Zone Sets

Zone member, zone, and zone set names must follow these rules:

???Names must be between 1 and 64 characters long

???Characters used in names must be 7 bit ASCII characters

???The first character of a name must be a letter (a-z) and can be either upper case or lower case

???Other characters of the name (any characters besides the first character) can be a letter (a-z, either upper or lower case), a number (0-9), or a symbol ($ - ^ _).

???No spaces are allowed in the name

MSA Fabric Switch 6 Management Utility

Zoning Limitations for Zone Members, Zones, and Zone Sets

There are zoning limitations for individual switches and fabrics. See Table 3-17 for maximum limitations.

Table 3-17: Switch and Fabric Zoning Limitations

Two Ways to Display Zoning

The MSA Fabric Switch 6 Management Utility allows you to display zoning in two ways:

???Merged zones

???Local zones

To toggle between the Merged Zones display and the Local Zones display, expand the Zoning View drop-down list in the Zoning Configuration screen.

Merged Zones

Use the Merged Zones display when you are interested in viewing information for zones merged with other switches on the Fabric.

This view is read-only and cannot be edited. The Merged Zones view is a Fabric-wide display showing the merged zones with other switches on the fabric.

NOTE: Because only one Zone Set can be active across the entire Fabric, only the Active Zone Set is shown.

MSA Fabric Switch 6 Management Utility

Local Zones

Use the Local Zones display when you are interested in viewing, creating, or editing zone sets, zones, and zone members for the switch presently being monitored.

This view is a read/write single-switch display showing the zone sets, zones, and zone members for that switch. You can create, edit and remove zone sets, zones, and zone members using the Local Zones view.

Using the Fabric Switch 6 Management Utility to Configure Zoning

Troubleshooting Guidelines

If there is a problem accessing a device connected to the switch, the source of the problem can be the MSA Fabric Switch 6 or any of the connections between the host and device. Use this chapter to troubleshoot the MSA Fabric Switch 6.

Troubleshooting

Troubleshooting the MSA Fabric Switch 6

If there is a problem accessing a device connected to the MSA Fabric Switch 6, the source of the problem can be with the device, the switch, the host, or any of the connections between the host and device. Follow the steps outlined below to investigate the problem. The following is a description of possible symptoms:

1.Check the Global Status Indicator for power. The unit may not be plugged into the Modular SAN Array 1000 correctly.

2.Inspect the switch fault indicators for apparent problems. If the fault indicators are on, the switch may be faulty or the temperature may be out of defined limits.

3.Inspect the cabling between the switch and attached Fibre Channel devices. Check for loose, dirty, broken, or bent cabling and connectors. If a Compaq- supported Small Form Factor Pluggable transceiver (SFP) is in use, check that it is properly inserted and that the cable is properly seated.

4.Check the port status indicators.

Reading the Global Status Indicator

The indicators provide information about the status of the switch. This should be used as the first stage in troubleshooting. If either the serial or the Ethernet link to the switch is running, use the appropriate Command Line Interface command (See Appendix C, ???Command Line Interface,??? for the appropriate command). The Global Status Indicator indicators can be interpreted by reviewing Table 4-1.

Troubleshooting

Table 4-1: Global Status Indicator

continued

Troubleshooting

Table 4-1: Global Status Indicator continued

Reading the Ethernet Indicators

Table 4-2: Ethernet Indicators

The network is down for some reason. Check to see if other systems on the network are functioning.

The switch is not connected to the network. Check the cable to see if it is seated properly. Try replacing the cable.

The switch is not functioning. Is the GSI power showing to the switch? Can you communicate with it via the serial port?

The switch may be connected to a network that is not 10Base T compatible. It could be 100BaseT only, or some other LAN link.

Troubleshooting

Reading the Port Indicators

Table 4-3: Port Link Indicators

Serial Communication Problems

The RS-232 interface can be the source of interface variations. If problems can be traced to the serial cable, check that the cable is plugged-in correctly and that it has the correct pin connections.

Connections

The following section describes the proper use of Compaq-supported Small Form Factor Pluggable Transceivers (SFP) and Fibre Channel cables.

Troubleshooting

Compaq-supported Small Form Factor Pluggables (SFP)

Use caution when handling SFPs. Take normal precautions to protect them from a static electrical discharge and any other damage:

IMPORTANT: Always wear an anti-static wrist strap when handling Compaq-supported SFPs. They are static sensitive.

???Leave the device in its anti-static bag until ready to install it.

???Hold the SFP by its edges and handle it carefully.

???Always follow the Compaq-supported SFP manufacturer???s recommended procedures for cleaning the SFP. This is especially true of the type of solvent used for cleaning optical surfaces.

IMPORTANT: Do not install any SFP that appears physically damaged. This may result in permanent damage to the switch. Keep unused SFP connectors covered with the plugs that are shipped with them to prevent contamination from obscuring or attenuating the light signals.

Fibre Channel Cables

The MSA Fabric Switch 6 uses Fibre Channel cables to communicate with end-node devices. Loose or broken cables can cause a number of problems. Inspect the cabling between the MSA Fabric Switch 6 and attached Fibre Channel devices. Check for loose, dirty, broken, or bent cabling and connectors.

???Inspect the switch fault indicators for apparent problems.

???Check that the Compaq-supported SFP is properly inserted.

???Check the port status indicators.

???Check to see if the indicator located next to the special Fibre Channel interface cable connector is lit. If it is not, a viable connection to the Fibre Channel network has not been established.

Troubleshooting

Temperature Control

The MSA Fabric Switch 6 is designed to work in a normal room temperature environment, between 10?? and 40?? C (50?? F to 104 ?? F).

Preventive Maintenance Solutions

To protect the switch for longer use, Compaq recommends the following:

???Periodically vacuum the external surfaces of the switch to remove dust.

???Do not drop fiber optic cable connectors onto hard surfaces. This can cause internal glass fractures and intermittent signals.

???Keep unused cable ends covered to prevent contamination from obscuring or attenuating the light signals.

IMPORTANT: Always use an anti-static wrist strap while handling SFPs. These are static-sensitive devices.

???Keep unused Compaq-supported SFP connections covered to prevent contamination from obscuring or attenuating the light signals.

???Always follow the Compaq-supported SFP manufacturer???s recommended procedures for cleaning the SFP. This is especially true of the type of solvent used for cleaning optical surfaces.

???Never insert foreign objects into optical transmit and receive ports.

???Do not bend fiber cable to less than a 3-inch bend radius.

Regulatory Compliance Notices

Federal Communications Commission Notice

Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic devices, including computers, generate RF energy incidental to their intended function and are, therefore, covered by these rules. These rules place computers and related peripheral devices into two classes, A and B, depending upon their intended installation. Class A devices are those that may reasonably be expected to be installed in a business or commercial environment. Class B devices are those that may reasonably be expected to be installed in a residential environment (personal computers, for example). The FCC requires devices in both classes to bear a label indicating the interference potential of the device as well as additional operating instructions for the user.

The rating label on the device shows which class (A or B) the equipment falls into. Class B devices have an FCC logo or FCC ID on the label. Class A devices do not have an FCC ID on the label.

Electrostatic Discharge

To prevent damage to the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

To prevent electrostatic damage, observe the following precautions:

???Avoid hand contact by transporting and storing products in static-safe containers.

???Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.

???Place parts on a grounded surface before removing them from their containers.

???Avoid touching pins, leads, or circuitry.

???Always make sure you are properly grounded when touching a static-sensitive component or assembly.

Electrostatic Discharge

Grounding Methods

There are several methods for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:

???Use a wrist strap connected by a ground cord to a grounded workstation or

computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm

?? 10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

???Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats.

???Use conductive field service tools.

???Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an Authorized Compaq Reseller install the part.

NOTE: For more information on static electricity, or for assistance with product installation, contact your Compaq authorized reseller.

Setting up Zoning

Zoning is a function of the MSA Fabric Switch 6 that allows you to create isolated Fibre Channel networks with a limited number of connected devices. By limiting the number of devices in a zone, you can obtain more robust performance and enhance your access protection.

Zoning is compliant with the following standards:

???FC-SW-2

???FC-GS3

???FC-MI

This section describes the zoning functions supported by the MSA Fabric Switch 6. It describes zoning at the individual switch and describes how the merge command functions are used to support zoning across a Fabric.

Zoning Elements

Before performing zoning, you must understand the following zoning elements:

???Zone Members

???Zones

???Zone Sets

CAUTION: Never add a zoned switch to an established fabric that has no zoning. If a switch configured with zoning is added to a fabric that has no configured zoning, the fabric???s HBAs and targets will no longer be able to communicate and the traffic in the fabric will be disrupted. For best results, only add a switch configured with zoning to a fabric configured with same zoning configuration.

Command Line Interface

Zone Members

Zone members are Fibre Channel edge devices that are identified by their World Wide Port Name (WWPN). Any device that you want to include in a zone must be identified as a zone member. While internally the zone members are tracked by their WWPN, you can create a Zone Member Name that acts as an alias for the device. This makes it easier to identify the devices during configuration and operation. The following are examples of Fibre Channel devices that can be named as zone members:

???Servers

???Raid systems

???Disk drives

???Tape libraries

IMPORTANT: The World Wide Node Name (WWNN) of the Fibre Channel device cannot be used to create a zone member. WWNN-bases zoning is expressly prohibited in the FC-MI standard. Use World Wide Port Name (WWPN) to create a zone member.

Zones

Zones are logical entities that represent groupings of zone members. Each zone must assigned a unique zone name when it is defined.

Zone Sets

Zone sets are logical entities that represent groupings of zones. They define a zoning configuration. Each zone set is assigned a unique zone set name when it is defined. The MSA Fabric Switch 6 allows storing of multiple zone sets. However, only one of these zone sets can be active at a time. The other zone sets can be used as backup, trials, or other user-defined configurations.

Command Line Interface

Naming Rules for Zone Members, Zones, and Zone Sets

Zone member, zone, and zone set names must follow these rules:

???Names must be between 1 and 64 characters long

???Characters used in names must be 7 bit ASCII characters

???The first character of a name must be a letter (a-z) and can be either upper case or lower case

???Other characters of the name (any characters besides the first character) can be a letter (a-z, either upper or lower case), a number (0-9), or a symbol ( $ - ^ _).

???No spaces are allowed in the name

Zoning Limitations for Zone Members, Zones, and Zone Sets

There are zoning limitations for individual switches and fabrics. See Table C-3 for maximum limitations.

Table C-3: Switch and Fabric Zoning Limitations

Command Line Interface

Using the CLI to Configure Zoning

This section describes how to use the CLI to configure zone members, zones, and zone sets and apply the new or edited zone configurations to the switch.

To ensure uninterrupted operation of the MSA Fabric Switch 6, a three-stage process was developed for configuring zoning using CLI:

???Stage one: creating the pending table

???Stage two: verifying the zoning configuration in the pending table

???Stage three: writing the pending table to the active table

The zoning configuration procedures are detailed in the following paragraphs and use the following scenario.

Assume the following:

???Server1 needs to access Disk1 exclusively for Operating System boot (OS Boot).

???Server1 needs to access Raid1 for shared storage.

???Server1 needs to access Tape1 for backup.

???Server2 needs to access Disk2 exclusively for Operating System boot.

???Server2 needs to access Raid1 for shared storage.

???Server2 needs to access Tape1 for backup.

Before you begin to configure your zoning, you must first define the zone members, zones, and zone sets that you will need.

Table C-4 lists the zone members, zones, and zone sets being used in this example and indicates what members the zones and the zone sets contain.

Command Line Interface

Table C-4: Example Zoning Configuration

In this example, the Zone Set MIS_NT-CLSTR1_SAN1 contains two zones:

???Web_Zone contains the following Zone Members: Server1, Disk1, RAID1, and Tape1.

???Mail_Zone contains the following Zone Members: Server2, Disk2, RAID1, and Tape1.

Stage one: Creating the Pending Table

Before configuring the zoning, it is helpful to decide on the names you will use for your zone sets, zones, and zone members.

During the configuration, you first create the largest group (zone sets), then create the next largest group (zones), and last create the individual entities (zone members).

After you have created your zone members using their WWPN, you can assign more user-friendly names to your zone members.

Command Line Interface

The steps of stage one include:

???Viewing and clearing the pending table

???Creating the zone set

???Adding zones to the zone set

???Adding zone members to the zones

???Changing the names of the zone members (optional)

???Enabling the pending table zone set

Viewing and Clearing the Pending Table

Start by checking what has already been created:

1. View the pending table.

NOTE: You can also use abbreviated forms of CLI commands. For example, instead of using ???cmd> zone pending,??? you can use ???cmd> zn pn.??? For a list of the CLI abbreviations, type ???help.???

2.Clear the existing pending table. cmd> zone clear

Cleared pending zone configuration.

3.Display the pending table to verify that it was cleared. cmd> zone pending

Zone table is empty.

Command Line Interface

Creating the Zone Set

Create your zone set using the name you already defined (see Table C-4).

cmd> zone addzs MIS_NT_CLSTR1_SAN1 Zoneset [MIS_NT_CLSTR1_SAN1] added.

Laser Precautions and

Fibre Channel Cables

Laser Precautions

WARNING: To reduce the risk of injury from laser radiation or damage to the equipment, observe the following precautions:

???Allow only Compaq Authorized Service Technicians to repair the equipment.

???Do not open any panels, operate controls, make adjustments, or perform procedures to a laser device other than those specified herein.

???Do not stare into laser beam when panels are open.

SFP and Fibre Channel Cable Connector Cleaning Considerations

Optics are susceptible to anything that hinders light transmission. Consequently, manufacturers of both 2-Gb Small Form Factor Pluggable Transceiver modules (SFP) and Fibre Channel Cable Connectors provide dust covers to protect the optical areas and ensure optical signal integrity for initial system configuration. If the fiber optic interconnects are disengaged, the optical tips can be soiled by human touch, damaged from dropping, or simply collect dust debris when exposed to the open air for extended time periods. A contaminated optic tip may not be visible to the naked eye and could potentially degrade performance of your system.

Laser Precautions and Fibre Cables

To minimize the risk of optic contamination on your system, keep the following fibre optic handling guidelines in mind:

???Dust Covers: Dust Covers are provided with all optical components and should be kept in place when not used. Do not throw away the dust covers after initial installation. You may need them to protect optical interconnect areas if reconfiguration is required.

???When to Clean: The best rule of thumb for cleaning fiber optics is common sense. If you have handled fiber optic interconnects and think there may be contamination, clean it. If you need to use a fiber optic interconnect component that is found without the dust covers in place, clean it.

???How to Clean: First, wipe the optics with a lint-free tissue soaked in 100 percent Isopropyl alcohol. Next, wipe optics with a dry lint-free tissue and dry with compressed/canned air.

Fibre Channel Cable

The MSA Fabric Switch 6 is intended primarily for use with Shortwave SFPs and multi-mode Fibre Channel cables. While Longwave SFPs can be used with 9 um single-mode Fibre Channel cables, performance may not be optimal due to transmission latencies.

SW-SFPs and Multi-mode Fibre Channel cables are capable of supporting distances of 2 meters to 500 meters. These cables are for use with Shortwave SFPs only. However, three multi-mode Fibre Channel cable option kits are available from Compaq if longer lengths are desired. Each kit contains a multi-mode Fibre Channel cable with a connector attached to each end. The Modular SAN Array 1000 storage systems and associated host bus adapters ship standard with 2m and 5m Fibre Channel cables, respectively. Other available kits are:

???15-meter multi-mode Fibre Channel Cable option kit (part number 234457-B23)

???30-meter multi-mode Fibre Channel Cable option kit (part number 234457-B24)

???50-meter multi-mode Fibre Channel Cable option kit (part number 234457-B25)

To customize your system with multi-mode Fibre Channel cable at distances greater than 50 meters, contact an independent Fibre Channel cable supplier.

Laser Precautions and Fibre Cables

If you are using an existing 62.5-micron cable in your infrastructure, you must obtain a 62.5-micron jumper from an independent source. A 50-micron cable cannot be spliced with a 62.5-micron cable.

CAUTION: Make certain the Fibre Channel cables are installed and supported so that no excess weight is placed on the Fibre Channel connectors. This is necessary to prevent damage to the connector and cable and to prevent a cable bend radius less than 3 inches (7.62 cm) at the connector and along the cable length. Excess Fibre Channel cable should be coiled and tied out of the way, being careful not to coil the cable in a tight loop with a bend radius of less than 3 inches (7.62 cm).
