Introduction

Overview

The Embedded Web Server (EWS) is a web-based graphical user interface (GUI),

based on HTML, that enables the user to administer products, monitor products

and ports, and perform tasks to manage a simple Storage Area Network (SAN).

You can also use EWS to perform troubleshooting tasks and upgrade product

firmware.

With product firmware 04.00.00 (or later) installed, administrators or operators

with a browser-capable PC and an Internet connection can monitor and manage

the product through the EWS interface.

The EWS interface supports product configuration, statistics monitoring, and

basic operation. The EWS interface neither replaces nor offers all of the

management capability of the High Availability Fabric Manager (HAFM) and its

Product Manager applications (for example, the EWS interface does not support

all product maintenance functions).

In addition, EWS provides hyperlink access to other products in a fabric, which

means those products can also be managed.

Using EWS to Perform Tasks

Users can perform the following tasks using EWS:

■ Display the properties and operational status of the product, FRUs, and Fibre

Channel ports; display product operating parameters; and display fabric parameters.

■ Configure the director or edge switch, including:

— Fibre Channel port parameters, port types, and data transmission speeds.

— Product identification, date and time, operating domain parameters, fabric

parameters, and network addresses.

17Embedded Web Server User Guide

Introduction

— Parameters for product management through Simple Network

Management Protocol (SNMP), the Command Line Interface (CLI), the Open System Management Server (OSMS) feature, or the Fibre Connection (FICON) Management Server (FMS) feature.

Note: The Edge Switch 2/24 does not support out-of-band management through FMS.

However, the Edge Switch 2/24 does support transmission of FICON frames.

— Zones and zone sets.

— User rights (administrator and operator).

■ Monitor ports and port statistics, and display the event log and node list.

■ Perform product operations and maintenance tasks, including:

— Enable unit beaconing, set the product online or offline, and perform a

configuration reset.

— Enable port beaconing, perform port diagnostics, and reset ports.

— Retrieve dump files and retrieve product information files.

— Install optional feature keys.

— Configure product Internet Protocol (IP) addresses, names, and SNMP

settings.

— Install new versions of product firmware.

— Manage user access to features.

— Control product ports on an individual basis.

— Troubleshoot problems using event log and error status indicators.

Administrators and operators can access real-time information about the product and fabric.

The EWS interface can be opened from a standard web browser running Netscape

Navigator 4.6 or higher or Microsoft

® Internet Explorer 4.0 or higher. At the web

browser, the user enters the IP address of the product as the Internet uniform

resource locator (URL). When prompted at a login screen, the user enters a user

name and password.

Note: The default user name is Administrator and the default password is password.

The user name and password are case-sensitive.

18 Embedded Web Server User Guide

Viewing the User Interface

When the EWS interface opens, the default display is the View page. Figure 1

shows an example EWS view with labels for the various parts of the image. This

example shows the Configure > Switch > Identification screen for the

Edge Switch 2/24. For other products, the corresponding page looks very similar.

Introduction

Figure 1: Example Embedded Web Server page for Edge Switch 2/24

As shown in Figure 1, particular terms are used when describing the EWS

interface:

■ Navigation panel — at the left of the screen is a menu of the various primary

views available on the screen. The navigation panel options include:

— View — At the View page, the Director or Switch (default), Port

Properties, FRU Properties, Unit Properties, Operating Parameters, and Fabric task selection tabs display.

— Configure — At the Configure page, the Ports (default), Director or

Switch, Management, Zoning, and User Rights task selection tabs display.

19Embedded Web Server User Guide

Introduction

— Monitor — At the Monitor page, the Port List (default), Port Stats,

Log, and Node List task selection tabs display.

— Operations — At the Operations page, the Director or Switch (default),

Port, Maintenance, and Feature Installation task selection tabs display.

— Help — The Help option opens online user documentation that supports

the EWS interface. This manual supplements the online help that is included with the EWS interface.

■ Page — describes the entire screen except the navigation panel. When you

choose an item from the navigation panel, the corresponding page view displays. For example, choose Configure from the navigation panel to view the Configure page.

■ Ta b — describes a label for a viewing option on a page, such as the Switch

and Identification tabs shown in Figure 1. Task selection tabs display at the top of the page. The task selection tabs allow users to perform director- or switch-specific tasks.

■ Ta b vie w — describes the fields, buttons, and labels that display when you

click on a tab. The tab view contains the information you are trying to access and activities that you can complete.

■ Date and Time — specifies the time when the information shown on the page

view was last updated.

Benefits

The EWS interface provides the following benefits:

■ Enables a single product to be managed from a single point of access.

■ Allows an administrator to manage a product from any location (such as their

office, a raised floor area, or a conference room) within the company’s public/private networks.

■ Enables an administrator to view the most current information about a product

upon accessing the product.

(This easy access provides a single point of product administration that is not limited to the location of an application or special hardware.)

20 Embedded Web Server User Guide

Key Terms

Introduction

■ Protects the authorized rights of users to perform tasks through roles defined

as operators and administrators.

(This protection enables companies to decide who should perform everyday tasks, such as monitoring product status, and sensitive tasks, such as installing firmware updates. This flexible approach enables companies to define roles within their organization while providing a level of security against unauthorized access.)

■ Enables users to simply start a web browser, enter the network address of the

product, and log in to start using EWS.

(No additional installation is required. EWS is ready and available to perform administration tasks once the hardware is installed and connected to the Ethernet network.)

■ Allows users to utilize a familiar web browser-based graphical user interface

that uses standard web browser applications for access.

■ Allows users to obtain assistance in performing tasks through online help.

This section provides key terms that will help you perform tasks, especially tasks

such as zoning.

Fabric

Entity that interconnects N_Ports and is capable of routing (switching) Fibre

Channel frames using the destination ID information in the Fibre Channel frame

header accompanying the frames.

21Embedded Web Server User Guide

Introduction

Storage Area Network (SAN)

A high-performance data communications environment that interconnects

computing and storage resources so that the resources can be effectively shared

and consolidated.

Zone (Zoning)

A zone is a group of devices or zone members in a SAN that can communicate

and access each other. Communication is only allowed between devices in the

same zone. A device can be in multiple zones so that shared resources can be

accessed by many devices. Because SANs connect many types of devices that

may carry different protocols, separating an entire fabric into zones can control

access between specific devices. Zone (or zoning) is an efficient method of

managing, partitioning, and controlling access to SAN devices. Zoning maximizes

resources while maintaining data security and enabling heterogeneous systems

and products to operate in the same SAN.

Zone Member

Specification (definition) of a device that belongs to a zone. A zone member can

be identified by the port number of the device to which it is attached or by its

device or host bus adapter or World Wide Name (WWN). In multiswitch fabrics,

identification of end-devices and nodes by WWN is preferable.

Zone Set

A zone set is composed of one or more zones. When a zone set is activated, all

zones in the set are activated at the same time. Only one zone set can be active in

the fabric at one time, and that zone set is referred to as the active zone set.

Where to Start

Depending upon whether the Hewlett-Packard product you purchased has already

been installed, you may need to go to a specific chapter. If the product has not

been installed, you should start at Chapter 2.

If the product was installed, then many of the configuration tasks were probably

already completed. In that case, you may need to configure a zone. Configuring

(including adding, deleting, and changing) zones is described in Chapter 3.

If the products have been configured and you have a functioning SAN, then you

most likely will be interested in performing system administration tasks. Those

tasks are described in Chapter 4, Chapter 5, and Chapter 6.

If you need to perform troubleshooting, then you will want to review Chapter 5

and Chapter 6.

Starting EWS

Open the EWS interface as follows:

1. Ensure the workstation (or device you use to launch the web browser) and the Ethernet LAN segment containing the product, such as Edge Switch 2/24, are attached and connected through the Internet.

Introduction

Note: You must be able to make a connection between the web browser and the

product in order to login to the product.

2. Launch the web browser application (such as Netscape Navigator, version 4.6 or higher, or Microsoft Internet Explorer, version 4.0 or higher).

3. At the web browser, enter the IP address of the product as the Internet uniform resource locator (URL) such as http://10.1.1.11.

Note: If the product has not been installed, refer to the product’s installation and

service manual for the appropriate IP address, login ID, and password that is initially used when you install and configure the product.

23Embedded Web Server User Guide

Introduction

After a connection is made between the web browser and the product, the Enter Network Password dialog box displays as shown in Figure 1.

Figure 2: Enter Network Password dialog box

4. Type the user name and password. The EWS interface opens with the View page displayed, as shown in Figure 3.

Note: The default user name is available from the installation and service guide that

was shipped with the product. The user name and password are case-sensitive. Also, during installation, the default values may have been changed. If defaults have changed, contact your system administrator for the valid user names and passwords.

25Embedded Web Server User Guide

Configuring the Product

Factory Default Values

HP products on a SAN have preset, default configuration values that were set in the factory. The items that have factory-set default values are:

■ Passwords (customer and maintenance-level)

■ Internet Protocol (IP) address

■ Subnet mask

■ Gateway address

The specific default values associated with a particular HP product are documented in the installation and service manual for the product.

Configuring Ports

Perform procedures in this section to configure names and operating characteristics for Fibre Channel ports. To configure one or more ports:

1. If you are going to change the Speed parameter on an Director 2/64, set the product offline as follows:

a. Choose Operations from the navigation panel. The Operations page

displays.

b. Click the Online State tab, then click Set Offline. The following message

displays: Your operations changes have been successfully activated.

2. At the EWS screen, choose Configure from the navigation panel. The Configure page and the Ports tab view display (Figure 4).

Note: Because the Director 2/140 has many ports, the listing of ports is divided into

separate displays, which are accessed by clicking the hyperlinks 1-31, 32-63, 64-95, 96-127, and 132-143. (Ports 128 through 131 are internal ports and not available for external connections.) If you make any changes to a particular list of ports, click Activate before selecting another list of ports. If you do not click Activate, changes are not implemented on the director.

26 Embedded Web Server User Guide

Configuring the Product

Figure 4: Configure Ports tab view

a. For each port to be configured, type a port name of 24 alphanumeric

characters or less in the associated Name field.

Note: When naming ports, you may want to name each port based on the device

attached to the port. For example, if the port is attached to an e-mail server, you might name the port email1 server port 2. The important point is to relate the name of the port to the device that is attached to the port.

b. Click a check box in the Blocked column to block or unblock a port

(default is unblocked). A check mark in the box indicates a port is blocked. Blocking a port prevents the attached devices or HP products in the fabric from communicating. A blocked port continuously transmits the offline sequence (OLS).

c. Click the check box in the FA N column to enable or disable the fabric

address notification (FAN) feature (default is enabled). (The FAN column is available only on the Edge Switch 2/24.) A check mark in the box indicates FAN is enabled. When the feature is enabled, the port transmits a FAN frame after loop initialization to verify that Fibre Channel Arbitrated Loop (FC-AL) devices are still logged in. It is recommended this option be enabled for ports configured for loop operation.

27Embedded Web Server User Guide

Configuring the Product

Note: If a device is connected and logged in to the fabric when extended distance is

enabled or disabled on the corresponding port, the HP product sends OLS for 5 milliseconds to force the device to log in again and obtain the new BB_Credit value set for the port.

d. Click a check box in the 10-100 km column to define extended distance

buffering. (This column is not available on the Edge Switch 2/24.) A check mark in the box indicates extended distance buffering is enabled. You can enable extended distance for a port even if it is not an extended distance port. However, enabling extended distance buffering for a port disables the ability of the port to send broadcast traffic. When you choose this option, the port can support up to 60 buffer-to-buffer credits (BB_Credits) to handle link distances up to 100 km. This enables the port to process 2K frames from attached devices. If this option is not enabled, the port uses the BB_Credit value.

e. Choose from the drop-down list in the Ty pe column to configure the port

type. Available selections are:

— G_Port — Generic port.

— F_Port — Fabric port.

— E_Port — Expansion port.

— GX_Port — Generic mixed port. Use this selection to configure a

port as a generic loop port (GL_Port). The port automatically negotiates any connection type (Edge Switch 2/24 only).

— FX_Port — Fabric mixed port. Use this selection to configure a port

as a fabric loop port (FL_Port). The port automatically negotiates F_Port and FL_Port connections only (Edge Switch 2/24 only).

f. Choose from the drop-down list in the Speed column to configure the port

transmission rate. Available selections are:

— Negotiate — Auto-negotiate between 1.0625 and 2.125 gigabits per

second (Gbps) operation. This is valid only on products that are capable of 2 Gbs operation.

— 1 Gb/sec — 1.0625 Gbps operation.

— 2 Gb/sec — 2.125 Gbps operation.

b. At the Insistent Domain ID field, choose Enabled or Disabled. When

this parameter is enabled, the domain ID configured in the Preferred Domain ID field becomes the active domain identification when the fabric initializes. (The Insistent Domain ID is automatically enabled if the SANtegrity Binding feature is installed.)

Note: If Enterprise Fabric Mode (an optional SANtegrity Binding feature) is enabled,

then Insistent Domain ID must be enabled.

c. At the Rerouting Delay field, choose Enabled or Disabled. When this

parameter is enabled, traffic is delayed through the fabric by the specified error detect time out value (E_D_TOV). This delay ensures Fibre Channel frames are delivered to their destination in order, even if a change to the fabric topology creates a new (shorter) transmission path. This parameter is only applicable if the product is being configured in a multiswitch fabric.

Note: If Enterprise Fabric Mode (an optional SANtegrity Binding feature) is enabled,

then Rerouting Delay

Configuring Open Trunking

The Open Trunking page enables you to configure open trunking settings. Open Trunking is an optional software feature that is enabled using a feature key.

The purpose of Open Trunking is to make efficient use of redundant interswitch links (ISLs) between neighboring switches by means of load balancing. ISLs are fiber optic cables that connect ports between Fibre Channel switches and link these switches into a multiswitch fabric. Fibre Channel traffic flows through these ISLs from end devices (servers and storage devices) attached to ports on individual switches.

When the traffic on a particular port exceeds a specified threshold, the Open Trunking functionality routes some of the traffic to another ISL. This prevents traffic from becoming congested on an ISL. Open trunking provides automatic, dynamic, statistical traffic load balancing across ISLs in a fabric environment.

The Open Trunking feature monitors Fibre Channel data rates through multiple ISLs, dynamically applies a fibre shortest path first (FSPF) networking algorithm to calculate the optimum path between fabric elements, and balances the Fibre Channel traffic load accordingly. The objective is to make the most efficient possible use of redundant ISLs between neighboring switches, even if these ISLs have different bandwidths.

Configuring the Product

The Open Trunking feature monitors the average data rates of all traffic flows (from a transmit port to a destination domain), and periodically adjusts routing tables to reroute data flows from congested links to lightly loaded links and optimizes bandwidth use.

Load-balancing among the ISLs does not require user configuration, other than enabling open trunking and selecting optional or default settings for congestion thresholds (per port) and a response threshold for lack of BB_Credits. In particular, you do not need to manually configure ISLs into trunk groups of redundant links where data can be off-loaded.

Candidate links for rerouting flow are identified automatically and maintained by the FSPF protocol. All ISLs that lead to adjacent switches on the shortest path to the flow’s destination are considered. This means that even if a link is not on the shortest path to the destination, the flow may be rerouted to this link to relieve congestion. This also means that flow may be rerouted onto a link that goes to a different adjacent switch.

4. Choose Enabled or Disabled from the Unresolved Congestion Event Notification drop down list. If enabled, an unresolved congestion entry is made in the event log and, if SNMP is configured, an SNMP trap is generated. Unresolved congestion occurs when a flow cannot be rerouted to another link because it would exceed the other link's threshold.

5. Choose Enabled or Disabled from the Backpressure Event Notification drop down list. If enabled, a backpressure entry is made in the event log and, if SNMP is configured, an SNMP trap is generated. Backpressure occurs when the threshold of unavailable BB_Credits is exceeded for any link.

6. Specify a value for the Low BB Credit Threshold option, if desired.

Note: Earlier versions of this dialog box may display Credit Starvation Threshold

instead of the Low BB Credit Threshold.

The system monitors the percentage of time that the port experiences no transmit BB_credits on the link. The link cannot transmit without BB_credits. When the threshold is exceeded, the system reroutes flows away from the ISL that is experiencing this problem. This threshold is also used to prevent rerouting of traffic to an ISL that is experiencing a low BB_credit threshold condition. The enabled Default check box indicates that the default threshold value of 10% should be used rather than the value in the % entry field. This parameter must be a value in the range 1 to 99, if the Default box is not checked.

7. Specify a load-balancing threshold value in the Threshold % field for each port, if desired. Use this field to configure the value of the load-balancing threshold for each port. When this threshold is exceeded, the open trunking functionality offloads some of the traffic to another ISL. The threshold must be a value in the range 1 to 99, if the Default box is not checked.

Configuring Zones

Understanding Zoning

Designing zoning can be a complex task, especially for multiswitch fabrics. Consult with your managed product vendor’s professional services organization before configuring zoning.

This section is designed to help you understand the following concepts so that you can more efficiently use Embedded Web Server features to configure and manage zones across a multiswitch fabric:

■ Benefits of zoning.

■ How zoning works to control access to storage devices and servers across a

fabric.

■ Other methods of controlling access at the switch and at the server and device,

such as binding.

■ Merging zoned fabrics.

■ Basic terms and concepts of zoning that you must understand when

configuring zoning.

Controlling Access Across a Fabric

Embedded Web Server zoning features enable you to establish zoning across a fabric of devices attached to switches and directors by partitioning these devices into groups called zones. A zone consists of devices that can access each other through port-to-port connections. Devices in the same zone can recognize and communicate with each other; devices in different zones cannot.

System administrators create zones to increase security and prevent data loss or corruption by controlling access between devices (such as servers and data storage units), or between separate user groups (such as engineering or human resources).

55Embedded Web Server User Guide

Configuring Zones

Zoning allows an administrator to:

■ Establish barriers between devices that use different operating systems. For

example, it is often critical to separate servers and storage devices with different operating systems because accidental transfer of information from one to another can delete or corrupt data. Zoning prevents this by grouping devices that use the same operating systems into zones.

■ Create logical subsets of closed user groups. Administrators can authorize

access rights to specific zones for specific user groups, thereby protecting confidential data from unauthorized access.

■ Create groups of devices that are separate from devices in the rest of a fabric.

Zoning allows certain processes (such as maintenance or testing) to be performed on devices in one group without interrupting devices in other groups.

■ Allow temporary access between devices for specific purposes.

Administrators can remove zoning restrictions temporarily (for example, to perform nightly data backup), then restore zoning restrictions to perform normal processes.

Figure 18 illustrates three zones established on a single managed product with

four devices in each zone. Devices in each zone can communicate with and access devices only in their respective zones.

Controlling Access at the Switch

A port binding feature is available on switches and directors that allows you to bind a specific switch or director port to the WWN of an attached device for exclusive communication. This Port Binding feature is available through the Port Binding tab, which is under the Security tab of the Configure page view.

Controlling Access at the Server or Storage Device

Features available at the server or storage device can add methods, beyond zoning, to increase network security measures, differentiate between operating systems, and prevent data loss or corruption by controlling access between devices or between separate user groups (such as engineering or human resources).

Server-level access control is called persistent binding. Persistent binding uses configuration information stored on the server and is implemented through the server’s host bus adapter (HBA) driver. The process binds a server device name to a specific Fibre Channel storage volume or logical unit number (LUN), through a specific HBA and storage port WWN. In essence, this feature creates a reliable route across the fabric that sustains the small computer system interface (SCSI) connection between a server and storage device.

For persistent binding:

■ Each server HBA is explicitly bound to a storage volume or LUN, and access

is explicitly authorized (access is blocked by default).

■ The process is compatible with open system interconnection (OSI) standards.

The following are transparently supported:

— Different operating systems and applications.

— Different storage volume managers and file systems.

— Different fabric devices, including disk drives, tape drives, and tape

libraries.

■ If the server is rebooted, the server-to-storage connection is automatically

re-established.

■ The connection is bound to a storage port WWN. If the fiber-optic cable is

disconnected from the storage port, the server-to-storage connection is automatically re-established when the port cable is reconnected. The connection is also automatically re-established if the storage port is cabled through a different managed product port.

58 Embedded Web Server User Guide

Access can also be controlled at the storage device as an addition or enhancement to redundant array of independent disks (RAID) controller software. Data access is controlled within the storage device, and server HBA access to each LUN is explicitly limited (access is blocked by default). Storage-level access control:

■ Provides control at the storage port and LUN level, and does not require

■ Is typically proprietary and protects only a specific vendor’s storage devices.

Before establishing persistent binding or access control features at the storage device, consult with your managed-product vendor’s professional services organization.

Zoning Concepts

Zoning is configured by authorizing or restricting access to name server information associated with device ports that attach to product ports. A zone member is specified by the number of the product port to which a device is attached, or by the 8-byte WWN assigned to the HBA or Fibre Channel interface installed in a device. A device port can belong to multiple zones.

Zoning concepts include:

Configuring Zones

Naming Conventions for Zones and Zone Sets

The following naming conventions apply to zones and zone sets:

■ All names must be unique and may not differ by case only. For example,

myzone and MyZone are both valid individually, but they are not unique.

■ The first character of a zone set name must be a letter (A-Z, a-z).

■ A zone set name cannot contain spaces.

■ Valid characters are a-z, A-Z, 0-9, ^, -, _, and $.

■ A zone set name can have a maximum of 64 characters.

Zones

A zone contains a set of members that can access each other. Refer to Tabl e 3 on page 64 for details on the number of members that you can configure in a zone and the number of zones that you can configure with the EWS Configure Zone functions.

A zone member can be a switch or director port or the WWN of the device. Ports and devices spread throughout multiple managed products in a multiswitch fabric may be grouped into the same zone. Members of a zone can see each other; members in different zones cannot. The number of members that you can configure for a zone varies according to the number of zones in the zone set, the length of the zone names, and other factors, but is essentially bounded by the available nonvolatile random-access memory (NVRAM) in the managed product.

Note: Port numbers cannot be used for zone members if the interoperability mode for

the switch or director is set to Open Fabric 1.0 mode. In this case, you must use node WWNs as zone members.

The type of zone members identified for a zone may be mixed and matched. For example, two members may be specified by a port number and the third member by the WWN of the device.

Using WWNs

To identify a zone member by WWN, use the 16-digit WWN of the device. For example:

10:00:08:00:88:40:C0:D4

60 Embedded Web Server User Guide

Configuring Zones

In EWS the WWN displays with the switch or director manufacturer’s name before the WWN. The WWN is assigned to the Fibre Channel interface or HBA installed in devices such as servers or storage devices. Although the device may also have a node WWN, this WWN is not used for zoning identification.

Note: Nicknames can be assigned to the WWN using the HAFM Product Manager.

This functionality is not available in EWS.

The advantage of identifying a zone member as the WWN of the attached device is that the identification will not change if fiber cable connections to ports are rearranged. This is especially important if you are using spare ports. You can simply move the fiber cable to a spare port from a failed port and still maintain the zoning configuration.

The disadvantage of identifying a zone member by the WWN is that removal and replacement of a device HBA or Fibre Channel interface (thereby changing the device WWN) disrupts zone operation and may incorrectly include or exclude a device from a zone.

Using Port Numbers

To identify a zone member by port number, use the domain identification number of the managed product and the port number on that managed product. For example:

Domain 1, Port 1

Note: Port numbers cannot be used for zone members if the interoperability mode for

the switch or director is set to Open Fabric 1.0 mode.

Port numbers can be 0 through n, with n representing the number of ports on the managed product minus one. When you define a zone member by a port number, any device attached through that port is included in the zone. A port number that you assign as a zone member is automatically prefixed with the domain identification number of the managed product.

The advantage of identifying a zone member by port number is that if the HBA on an attached device fails, you don’t have to identify the member with the WWN of the replacement HBA.

61Embedded Web Server User Guide

Configuring Zones

Default Zone

A disadvantage of port zoning is that someone may rearrange cable connections to ports (because of port failures or other reasons) and inadvertently allow devices to communicate that should not have access to each other.

Note: If a managed product’s Domain ID changes, you must reconfigure all zones that

contained the managed product’s port as a zone member. We recommend assigning unique Preferred Domain IDs to each switch in the fabric. You can make these assignments using the EWS Configure page, Switch, Parameters tabs to change the Preferred Domain IDs.

A default zone consists of all devices that have not been configured as members of a zone in a currently-active zone set. The following are some important points to remember about zone sets:

■ You can enable or disable the default zone separately from the active zone set

by choosing the Zoning option from the Configure menu. Enabling the default zone allows all devices and ports not configured as members of the active zone set to communicate. If the default zone is disabled, these ports and devices cannot communicate.

■ When no zone set is activated, then all devices are considered to be in the

default zone.

■ If a zone set is active, then all connected devices that are not included as

members of a zone in the active zone set are included in the default zone.

Zone Sets

A zone set is a group of zones that you can activate or deactivate as a single entity across all managed products in either a single switch or a multiswitch fabric. Only one zone set can be active at one time. Devices that are members of zones in the zone set can only communicate with members of zones in the same zone set. However, devices can be included as members of more than one zone set. By activating a zone set, you are making all zones in the set active.

Refer to Tabl e 3 on page 64 for details on the number of zones and zone members that you can configure in a zone set and the number of zone sets that you can configure.

62 Embedded Web Server User Guide

The following are some important points to remember about zone sets:

■ If no zone set is active, and the default zone is disabled, then no devices can

communicate.

■ If you activate a zone set when there is already an active zone set, that set will

replace the currently-active zone set.

■ If you deactivate the current active zone set, then all devices connected in the

fabric become members of the default zone.

Active Zone Set

An active zone set is a zone set that is currently active on a single-switch fabric or across all managed products in a multiswitch fabric. At any time, you can disable zoning by deactivating the active zone set and enabling the default zone, or you can enable zoning by activating a zone set. When a zone set is active, all zones that are members of that zone set are active. Only one zone set can be active for the fabric at one time. If no zones are active, then all devices are considered to be in the default zone.

Merging Zoned Fabrics

Managed products are linked through Interswitch Links (ISLs) to form multiswitch fabrics. In a multiswitch fabric, the active zoning configuration applies to the entire fabric. Any change to the configuration applies to all switches in the fabric.

When fabrics join through an ISL, adjacent managed products exchange active zone configurations and determine if the configurations are compatible and can merge. Zoning configurations are compatible if the active zone names in each fabric are unique. If there are identical zone names in each fabric, then the zones must have identical members for the fabrics to join.

If the configurations can merge, the fabrics join. The resulting configuration will be a single zone set containing zone definitions from each fabric.

Configuring Zones

If configurations cannot merge, the expansion ports (E_Ports) on each product become segmented. Segmented E_Ports cannot carry traffic from attached devices (class 2 or 3 traffic), but can carry management and control traffic (class F traffic) between managed products.

63Embedded Web Server User Guide

Configuring Zones

Rules for Merging Zoned Fabrics

Certain rules are enforced to ensure that zoning is consistent across the fabric.

Tabl e 3 on page 64 summarizes rules for joining two fabrics through an ISL. The

following terms are used in the table:

■ Not zoned — No zone set is active in the fabric and the default zone is

enabled. In other words, all devices in the fabric are visible to all other devices in the fabric.

■ Zoned — A zone set is active in the fabric and/or the default zone is disabled.

In this case, devices can discover other devices that are members of the same zone.

■ Zoning configuration — Combination of the active zone set definition and the

default zone state (enabled or disabled).

each fabric are unique. The resulting active zone set is a union of the zones from each fabric. Once you have merged the two zoned fabrics, click the

Save active zone set as button in the Zoning view to save the active zone

set. If there is a zone name conflict (the

same zone name in each fabric) then the zones must have identical members for the fabrics to join.

If the two zones have the same name but contain different members, then the E_Ports will segment and the fabrics will not join.

64 Embedded Web Server User Guide

Note: If merging zones will result in segmented E_Ports and the fabrics will not join,

you can join the fabrics by deactivating the active zone set on one of the fabrics (default zone is enabled). This eliminates any conflicts because the fabrics will then join using only the active zone set. After the fabrics join, you can make adjustments to zoning configurations as you desire.

Configuring, Adding, or Deleting Zones

Perform this procedure to configure, change, add, or delete zones. A zone is a group of devices that can access each other through port-to-port connections. Devices in the same zone can recognize and communicate with each other; devices in different zones cannot.

Caution: If, in your business practices, zoning tasks are performed using both

the Command Line Interface (CLI) and EWS, you risk potential conflicts in the configuration and functionality could be lost.

To configure zones:

Configuring Zones

1. Choose Configure from the navigation panel.

2. At the Configure page, choose the Zoning tab and the Zones tab. The Zones tab view displays as shown in Figure 20.

3. To configure a zone, first add the zone name to the product configuration. The following naming conventions apply to zones and zone sets:

■ All names must be unique and may not differ by case only. For example,

zone-1 and Zone-1 are both valid individually, but are not considered unique.

■ The first character of a zone set name must be a letter

(A through Z or a through z).

■ A zone set name cannot contain spaces.

■ Valid characters are alphanumerics and the caret ( ^ ),

hyphen ( - ), underscore ( _ ), or dollar ( $ ) symbols.

■ A zone set name can have a maximum of 64 characters.

Note: A product can have a maximum of 1024 zones.

Monitoring Products

The Monitor page is used to access information about the product including port and node information as well as critical information about performance. Key tasks you can perform to troubleshoot problems from the Monitor page are:

■ Monitoring Ports on page 91

■ Accessing Port Statistics on page 94

■ Reviewing the Event Log on page 98

■ Viewing Node List on page 100.

Monitoring Ports

You can obtain information about ports from the Port List and Port Stats tab views.

Port List

Choose Monitor on the navigation panel. The Port List tab view displays (Figure 30). The Port List tab view provides the following information including information on the port state:

■ Port # — The number of the port.

■ Name — Displays the port name as configured through the Configure Ports

tab.

91Embedded Web Server User Guide

Monitoring Products

■ Block Configuration — Indicates the blocked or unblocked configuration of

the port:

— Blocked — Devices communicating with the port are prevented from

logging into the product or communicating with other devices attached to product ports.

— Unblocked — Devices communicating with the port can log in to the

product and communicate with devices attached to any other unblocked port in the same zone.

■ State — See “Port Operational States” in the next section for an explanation

of the states.

■ Type — The type of port. The valid options vary by product.

Figure 30: Port List tab view

Port Operational States

The State column of the Port List tab view displays one of the following operational states:

■ Beaconing — The port is beaconing, which means that the beaconing light

is flashing on the physical hardware. (A port in a failed state cannot beacon.)

■ Inactive — The switch port is in an inactive state. Reasons for this state

display in the Reason field of the Port Properties page. (See “Viewing Port

Properties” on page 75 for more information.)

92 Embedded Web Server User Guide

Monitoring Products

Note: Note that if port optics have also failed, the amber LED will be on.

■ Invalid Attachment — The switch port is in an invalid attachment

state.

■ Link Incident — A link incident occurred on one of the ports.

■ Link Reset — The switch and the attached device are performing a link

reset operation to recover the link connection. Ordinarily, this is a transient state.

■ No Light — No signal (light) is being received on the switch port. This is a

normal condition when there is no cable plugged into the port or when the power of the device attached to the other end of the link is off.

■ Not installed — The port optics are not installed or the feature that

provides additional port function is not enabled.

■ Not Operational — The switch port is receiving the Fibre Channel not

operational sequence (NOS) indicating that the attached device is not operational.

■ Online — The attached device has successfully connected to the switch and

is ready to communicate or is in the process of communicating with other attached devices.

■ Offline — The switch port was configured as “blocked” and is

transmitting the Fibre Channel OLS to the attached device.

■ Port Failure — The switch port has failed and requires service. (A port

in the failed state cannot beacon.)

■ Segmented E_Port — The E_Port is segmented preventing the two

fabrics from joining (this only occurs when two switches are connected to each other).

■ Testing — Port is executing an internal loopback test.

Accessing Port Statistics

Choose Monitor on the navigation panel. Choose the Port Stats tab; the Port Stats tab view displays (Figure 31).

To display port statistics for a selected port, enter a port number in the Port Number field and choose Get Port Statistics. (You can also choose the Back or Fwd buttons to view the previous or next port.) The Port Statistics are divided into

Traffic Statistics, Error Statistics, Class Two Statistics, and Class Three Statistics. (You may need to scroll down to see all of the categories.)

The information shown that displays is current as of the time when the view displays. The information does not update automatically.

Figure 31: Port Statistics tab view

Troubleshooting Tip for Port Stats

As a general rule, you should clear all the counters by choosing Clear Port Stats or Clear All Port Stats after you have resolved a problem. When troubleshooting, keep track of the time interval when errors accumulate to judge the presence and severity of a problem. (There is a link recovery hierarchy implemented in Fibre Channel to handle some level of “expected anomalies.”) For troubleshooting purposes, you want to focus on errors that, as displayed in the Counter column, increment very quickly.

94 Embedded Web Server User Guide

Parts of Statistics Tables

The tables of statistics contain the following columns:

■ Statistics — Type of statistic being tracked.

■ # of Wraps — Number of times the Counter value wraps, for statistics that

grow rapidly. The maximum value that either the Counter or the #ofWraps can hold is 2 maximum value of 2

■ Counter — Number of instances of the tracked item recorded since system

, or 4,294,967,296. Each time the Counter field reaches the

initialization or the last time the counters were cleared.

Traffic Transmit and Receive Statistics

The Traffic Statistics include these transmit and receive values.

■ Frames Rx — Number of frames that the port has received.

■ Frames Tx — Number of frames that the port has transmitted.

■ Four byte words Rx — Number of words that the port has received.

■ Four byte words Tx — Number of words that the port has transmitted.

■ Offline sequences Rx — Number of offline sequences (OLS) received by this

port.

Monitoring Products

, the wrap count is incremented by 1.

■ Offline sequences Tx — Number of offline sequences (OLS) transmitted by

this port.

■ Link resets Rx — Number of link reset protocol frames received by this port

from the attached N_Port.

■ Link resets Tx — Number of link reset protocol frames transmitted by this

port to the attached N_Port.

■ Link utilization % Rx — Current link utilization for the port expressed as a

percentage. On 1 Gbps links, ports can transmit or receive data at 100 MB per second. On 2 Gbps links, ports can transmit or receive data at 200 MB per second. Link utilization is calculated over one-second intervals.

■ Link utilization % Tx — Current link utilization for the port expressed as a

percentage. On 1 Gpbs links, ports can transmit or receive data at 100 MB per second. On 2 Gbps links, ports can transmit or receive data at 200 MB per second. Link utilization is calculated over one-second intervals.

Error Statistics

Monitoring Products

The Error Statistics include these transmit and receive values:

■ Link failures — Number of link failures recorded because a not operational

sequence (NOS), protocol timeout, or port failure was detected.

■ Sync losses — Number of loss-of-synchronizations detected because an

attached device was reset or disconnected from the port.

■ Signal losses — Number of loss-of-signal errors detected because the

attached device was reset or disconnected from the port.

■ Primitive sequence errors — Number of primitive sequence protocol errors

received from an attached device, which indicates a Fibre Channel link-level protocol violation.

■ Discarded frames — A received frame could not be routed and was

discarded because the frame timed out due to an insufficient buffer-to-buffer credit, or the destination device was not logged into the product.

■ Invalid transmission words — Number of invalid transmission words from

an attached device. This indicates that a frame or primitive sequence arrived at the port corrupted.

■ CRC errors — A received frame failed a cyclic redundancy check (CRC)

validation, indicating the frame arrived at the port corrupted. Frame corruption may be caused by device disconnection, an optical transceiver failure at the device, a bad fiber cable, or a poor cable connection.

■ Delimiter errors — Number of times that the switch detected an

unrecognized start-of-frame (SOF), an unrecognized end-of-frame (EOF) delimiter, or an invalid class of service. This indicates that the frame arrived at the switch’s port corrupted. This corruption can be due to plugging/unplugging the link, bad optics at either end of the cable, bad cable, or dirty or poor connections. Moving the connection around or replacing cables can isolate the problem.

■ Address ID errors — A received frame had an unavailable or invalid Fibre

Channel destination address, or an invalid Fibre Channel source address. This typically indicates the destination device is unavailable.

■ Frames too short — A received frame exceeded the Fibre Channel frame

maximum size or was less than the Fibre Channel minimum size, indicating the frame arrived at the switch’s port corrupted. Frame corruption may be caused by device disconnection, an optical transceiver failure at the device, a bad fiber cable, or a poor cable connection.

Open Trunking Statistics

The Open Trunking Statistics include these transmit and receive values:

■ Flows rerouted to ISL — The number of Fibre Channel traffic flows that

were rerouted to this ISL from another ISL due to congestion. (This value increments only if the Open Trunking feature is installed.)

■ Flows rerouted from ISL — The number of Fibre Channel traffic flows that

were rerouted from this ISL to another ISL due to congestion. (This value increments only if the Open Trunking feature is installed.)

Reviewing the Event Log

Choose Monitor on the navigation panel. Choose the Log tab; the Log tab view displays (Figure 32). This log displays a record of significant events that have occurred on the product, such as degraded operation, FRU failures, and port problems. The event log is an important tool you can use to monitor and troubleshoot the products in the SAN. Information contained in the event log may also be used by customer support and service personnel to help resolve problems.

The event log displays the date and time of the event, a unique error event code, event severity level, and additional event data in hexadecimal format.

Figure 32: Log tab view

Severity Levels

Severity levels are:

■ Informational

■ Minor

■ Major

■ Severe (not operational)

Error Event Code Categories

Error Event Codes define event categories; the categories and events vary by product. Below is a list of event codes:

■ 1xx-system events

■ 2xx-power supply events

■ 3xx-fan events

■ 4xx-control processor card events

■ 5xx-port or universal port module card events

Monitoring Products

■ 6xx-serial crossbar assembly (SBAR) events

■ 8xx-thermal incident events

For detailed information on event codes and isolating problems from events and record event data, see the product installation and service manual.

Note: In addition to the event log, another method to obtain operation information

about the status of the product is from the Fabric tab view. See Chapter 4 for more information.

There are two options available that you can use to clear either event logs or the system error light. These options are described below.
