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.

18 Embedded Web Server User Guide

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.

— 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.

Introduction

— Zones and zone sets. — User rights (administrator and operator). — Port binding, switch binding, fabric binding, and Enterprise Fabric

Management.er 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, turn off the system error light, 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.

19Embedded Web Server User Guide

Introduction

— 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.

20 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.

22 Embedded Web Server User Guide

Benefits

Introduction

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.)

■ 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.

Introduction

Key Terms

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.

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.

24 Embedded Web Server User Guide

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 “Configuring the Product” on page 29.

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 “Configuring

Zones” on page 81

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 “Viewing Product and Fabric Data” on page 99, “Monitoring Products” on page 117, and “Operating and Managing Products and

Parts” on page 135.

If you need to perform troubleshooting, then you will want to review “Monitoring

Products” on page 117 and “Operating and Managing Products and Parts” on

page 135.

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 a 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.

Configuring the Product

31Embedded Web Server User Guide

Configuring the Product

Figure 4: Configure Ports tab view

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.

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

characters or less in the associated Name field.

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 FA N 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.

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.

32 Embedded Web Server User Guide

Configuring the Product

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.

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.

e. Choose from the drop-down list in the Typ e 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 (Gb/s) operation. This is valid only on products that are capable of 2 Gbs operation.

— 1 Gb/sec — 1.0625 Gb/s operation. — 2 Gb/sec — 2.125 Gb/s operation.

3. Click Activate to save and activate the changes. The following message displays: Your changes to the port configuration have been successfully activated.

3. Click the Switch or Director tab, as appropriate. Click the Parameters tab to display the Parameters tab view (Figure 7).

Figure 7: Configure product Parameters tab view

a. At the Preferred Domain ID field, type a value of 1 through 31. The

domain ID uniquely identifies each product in a fabric.

Note: If the product is attached to a fabric element, the product and element must

have unique domain IDs. If the values are not unique, the E_Port connection to the element cannot carry traffic and the product cannot communicate with the fabric.

38 Embedded Web Server User Guide

Configuring the Product

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) or Fabric

Binding 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

must be enabled.

d. At the Domain RSCN field, choose Enabled or Disabled. When this

parameter is enabled, messages can be sent between end devices in a fabric to provide additional connection information to host bus adapters (HBA) and storage devices. Consult with your HBA and storage device vendor to determine if enabling Domain RSCNs will cause problems with your HBA or storage products.

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

then Domain RSCN must be enabled.

e. At the Suppress RSCN on Zone Set Activations field, choose Enabled

or Disabled. When this parameter is enabled, RSCN messages are prohibited from being sent to ports on the switch following any change to the fabric's active zone set. Consult with your HBA and storage device vendor to determine if enabling this parameter will cause problems with your HBA or storage products.

available for the Edge Switch 2/24.) Configure the product to support buffer-to-buffer credit (BB_Credit) from 1 through 60. This is the value used for all ports, except those configured for extended distance buffering (10—100 km). The default value is 16. For a description of the buffer-to-buffer credit, refer to industry specification, Fibre Channel Physical and Signaling Interface.

b. At the R_A_TOV field, type a value between 10 through 1200 tenths of

a second (1 through 120 seconds). (The R_A_TOV value must be greater than the E_D_TOV value.)

Note: If the product is attached to a fabric element, the product and element must be

set to the same R_A_TOV value. If the values are not identical, the E_Port connection to the element fails and the product cannot communicate with the fabric.

c. At the E_D_TOV field, type a value between 2 through 600 tenths of a

second (0.2 through 60 seconds). (The E_D_TOV value must be less than the R_A_TOV value.)

Note: If the product is attached to a fabric element, the product and fabric element

must be set to the same E_D_TOV value. If the values are not identical, the E_Port connection to the element fails and the product cannot communicate with the fabric.

d. Choose from the Switch Priority drop-down list to set the product

priority. Available selections are Default, Principal, and Never Principal. The default setting is Default.

This value designates the fabric’s principal switch. The principal switch is assigned a priority of 1 and controls the allocation and distribution of domain IDs for all fabric elements (including itself).

Principal is the highest priority setting, Default is the next highest, and Never Principal is the lowest priority setting. The setting Never Principal means the switch is incapable of becoming a principal switch.

If all switches are set to Principal or Default, the switch with the highest priority and the lowest World Wide Name (WWN) becomes the principal switch.

At least one switch in a fabric must be set as Principal or Default. If all switches are set to Never Principal, all interswitch links (ISLs) will segment, causing a failure of connectivity.

e. Choose from the Interop Mode drop-down list to set the product

operating mode. This option does not display if the operation mode is S/390. (S/390 mode is not supported with the Edge Switch 2/24.)

Note: The operation mode parameter in the EWS interface is equivalent to the

management style parameter in the HAFM interface. The S/390 mode used for the EWS interface is equivalent to the FICON management style in the HAFM.

This setting only affects the mode used to manage the product; it does not affect port operation. Available selections are:

Configuring Switch Binding

Switch Binding functionality enables you to identify the devices with which the switch or director can communicate. Switch Binding is available only if the SANtegrity Binding feature is installed.

The Switch Binding tab view allows you to enable the product to communicate only with devices that are listed on the Switch Binding Membership List (SBML). Switch Binding restricts connections to only the devices listed on the SBML and allows no other devices to communicate with the switch. When an unauthorized WWN attempts to log in, it is denied a connection and an event is posted to the event log. This provides security in environments that include a large number of devices by ensuring that only the specified set of devices are able to attach to a switch or director.

You can use the Switch Binding tab to enable Switch Binding and to create and change the SBML.

Note: Switch Binding can also be enabled by enabling the Enterprise Fabric Mode.

For more information, see “Switch Binding and the Enterprise Fabric Mode” on page 72.

Enable, Disable, and Online State Functions

For Switch Binding to function, specific operating parameters and optional features must be enabled. Also, there are specific requirements for disabling these parameters and features:

■ Switch Binding can be enabled or disabled whether the product is offline or

online.

■ Enabling Enterprise Fabric Mode automatically enables Switch Binding.

■ You cannot disable Switch Binding if Enterprise Fabric Mode is enabled.

However, if Enterprise Fabric Mode is disabled, you can disable Switch Binding.

■ If Enterprise Fabric Mode is enabled and the director or switch is online, you

cannot disable Switch Binding.

■ If Enterprise Fabric Mode is enabled and the director or switch is offline, you

can disable Switch Binding, but this also disables Enterprise Fabric Mode.

58 Embedded Web Server User Guide

■ WWNs can be added to the SBML without regard to whether Switch Binding

is enabled or disabled.

■ If the director or switch is online and Switch Binding is not enabled, all nodes

and switches attached to the director or switch are automatically added to the SBML.

Configuring Fabric Binding

Fabric Binding functionality, provided by the SANtegrity Binding feature, allows you to bind the switch or director to specified fabrics so that it can communicate only with those fabrics. With Fabric Binding enabled, the product can communicate only with fabrics that are included in the Fabric Binding Membership List (FBML).

Using Fabric Binding, you can allow specific switches to attach to specific fabrics in the SAN. This provides security from accidental fabric merges and potential fabric disruption when fabrics become segmented because they cannot merge.

The Fabric Binding tab allows the user to modify Fabric Binding configuration, to save and activate any changes that have been made to Fabric Binding configuration, and to deactivate Fabric Binding. Fabric Binding is available only if the SANtegrity Binding feature is installed.

Fabric Binding Membership Terminology

The following terms apply to FBMLs and their members, as they are configured using the EWS interface. Two types of FBMLs are configured using the Fabric Binding tab.

Configuring the Product

■ Active FBML — When fabric binding is active, the active FBML is the list of

fabric members with which the product is allowed to communicate. If fabric binding is disabled, this list is empty.

■ Pending FBML — A list shown on the Fabric Binding tab, used to configure

an FBML before it is made active on the product. Changes to the pending FBML are not implemented in the fabric until they are saved and activated.

The following terms apply to the switches or directors that are part of the FBMLs:

■ Local — The switch or director product that you are configuring. This is a

required FBML member.

■ Attached — A switch or director that is currently in a fabric with the local

product. Any switch or director that is attached is a required FBML member.

■ Unattached — A switch or director that is not currently in a fabric with the

local product. These switches and directors are unattached if they have been added manually to the pending FBML, or if the ISL between the local product and the switch or director was removed.

Enable, Disable, and Online State Functions

In order for Fabric Binding to function, specific operating parameters and optional features must be enabled. Also, there are specific requirements for disabling these parameters and features when the director or switch is offline or online. Be aware of the following:

■ Because switches are bound to a fabric by WWN and domain ID, the Insistent

Domain ID function is automatically enabled if Fabric Binding is enabled. You cannot disable Insistent Domain ID while Fabric Binding is active and the switch is online. (For information about configuring the domain ID of the product, see “Configuring Operating Parameters” on page 38.)

■ If Fabric Binding is enabled and the switch is online, you cannot disable

Insistent Domain ID.

■ If Fabric Binding is enabled and the director or switch is offline, you can

disable Insistent Domain ID, but this will disable Fabric Binding.

■ You cannot disable Fabric Binding if Enterprise Fabric Mode is enabled.

However, if Enterprise Fabric Mode is disabled, Fabric Binding can be enabled or disabled.

Fabric Binding and the Enterprise Fabric Mode

Fabric Binding is a SANtegrity Binding feature that prohibits switches and directors from communicating with switches or directors that are not part of the fabric. Refer to “Configuring Fabric Binding” on page 63 for details on configuring Fabric Binding.

When the Enterprise Fabric Mode is enabled, Fabric Binding is enabled automatically. The fabric members that are currently attached to the product are added automatically to the active Fabric Binding Membership List (active FBML), a list of switches and directors that are allowed to communicate with the product. Therefore, when Enterprise Fabric Mode is enabled, the fabric members that are currently attached to the product participate in Fabric Binding. To add other fabrics to the active FBML, see “Configuring the Pending FBML” on page 67.

Switch Binding and the Enterprise Fabric Mode

Switch Binding is a SANtegrity Binding feature that enables switches or directors to communicate only with devices that are listed on the Switch Binding Membership List (SBML). When the Enterprise Fabric Mode is enabled, Switch Binding is also enabled. You need to configure the SBML, which specifies the devices with which the switch or director can communicate. Refer to “Configuring Fabric Binding” on page 63 for details on configuring Switch Binding.

Rerouting Delay and the Enterprise Fabric Mode

Rerouting Delay ensures that frames are delivered through the fabric to their destination in the correct order, even if the path changes. If traffic to a particular destination is going to be rerouted over a shorter path, the rerouting delay function prevents new traffic from being released before the existing traffic arrives at its destination.

If a change to the fabric topology creates a new path (for example, a new switch is added to the fabric), frames may be routed over this new path if its hop count is less than a previous path with a minimum hop count. This situation could result in frames being delivered to a destination out of order because frames sent over a new, shorter path may arrive before frames sent previously using the older, longer path.

72 Embedded Web Server User Guide

If Rerouting Delay is enabled, traffic ceases in the fabric for the time specified in the E_D_TOV field of the Configure Fabric Parameters dialog box (for more information, see “Configuring Fabric Parameters” on page 41). This delay enables frames sent using the old path to arrive at their destination before frames begin traversing the new path.

If Enterprise Fabric Mode is enabled, Rerouting Delay is automatically enabled and cannot be disabled unless the director or switch is offline. In this case, disabling Rerouting Delay also disables Enterprise Fabric Mode. For information about configuring and enabling Rerouting Delay, see “Configuring Operating

Parameters” on page 38.

Domain RSCNs and the Enterprise Fabric Mode

Domain register for state change notifications (domain RSCNs) are sent between end devices in a fabric to provide additional connection information to host bus adapters (HBA) and storage devices. As an example, this information might be that a logical path has been broken because of a physical event, such as a fiber optic cable being disconnected from a port.

If Enterprise Fabric Mode is enabled, Domain RSCNs are automatically enabled and cannot be disabled unless the director or switch is offline. In this case, disabling Domain RSCNs also disables Enterprise Fabric Mode. For information about enabling Domain RSCNs, see “Configuring Operating Parameters” on page 38.

Configuring the Product

Insistent Domain Identification (ID) and the Enterprise Fabric Mode

If enabled, Insistent Domain ID specifies that the preferred domain ID configured for the product will be the product’s active domain identification when the fabric initializes. For information about configuring the preferred domain ID, see “Configuring Operating Parameters” on page 38.

A static and unique domain ID is required by the Fabric Binding feature because the feature's FBML identifies switches by WWN and domain ID. If a duplicate preferred domain ID is used, then made insistent, warnings display when directors and switches are added to an FBML.

If Fabric Binding or Enterprise Fabric Mode is enabled, Insistent Domain ID is automatically enabled and cannot be disabled unless the director or switch is offline. In this case, disabling Insistent Domain ID disables Enterprise Fabric Mode and Fabric Binding. For information about configuring the domain ID and Insistent Domain ID, see “Configuring Operating Parameters” on page 38.

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.

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.

This parameter 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).

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.

82 Embedded Web Server User Guide

Configuring Zones

■ 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 21 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.

This Port Binding feature is available through the Port Binding tab, which is under the Security tab of the Configure page view.

84 Embedded Web Server User Guide

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.

Configuring Zones

■ 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.

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

configuration at the server.

■ 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:

■ Zones

■ Default Zone

■ Zone Sets

■ Active Zone Set

Storage-level access control may not be available for many legacy devices.

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 Table 3 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

86 Embedded Web Server User Guide

Configuring Zones

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

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.

87Embedded Web Server User Guide

Configuring Zones

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.

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.

Default Zone

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.

88 Embedded Web Server User Guide

Zone Sets

Configuring Zones

■ 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.

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.

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.

89Embedded Web Server User Guide

Configuring Zones

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.

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.

Rules for Merging Zoned Fabrics

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

Table 3 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).

Fabrics can merge if the zone names in 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 button in 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.

Configuring Zones

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:

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 23.

Figure 23: Configuring zones

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.

92 Embedded Web Server User Guide

Configuring Zones

■ 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.

4. Type the zone name and click Add New Zone. After the name is validated, the new zone name (Zone-1) and an associated Delete button display at the bottom of the page. Note the following:

■ Save and activate the zone — Changes to a zone or zoning configuration

are not saved and activated on the product until saved as part of a zone set. See “Configuring Zone Sets” on page 96 for information about performing this function.
