viii Zoning User’s Guide

Introducing Zoning

Zoning allows you to partition your Storage Area Network (SAN) into logical groupings of devices that can access each other. Using Zoning, you can arrange fabric-connected devices into logical groups, or zones, over the physical configuration of the fabric.

Zones can be configured dynamically. They can vary in size depending on the number of fabric connected devices, and devices can belong to more than one zone. Because zone members can access only other members of the same zone, a device not included in a zone is not available to members of that zone. This chapter discusses the following Zoning topics:

• Administering Security on pa ge 1-1

• Customizing Environment s on page 1-1

• Optimizing IT Resources on page 1-1

• Implementing Zoning on page 1-2

Chapter

Note: Zoning for interoperability is described in Merging Heterogeneous Fabrics Instructions,

which is available on the HP Surestore FC 1Gb/2Gb Switch 16B Documentation CD (A7340-11001) and the HP Surestore FC 1Gb/2Gb Entry Switch 8B and FC 1Gb/2Gb Switch 8B Documentation CD (A7346-11001).

Administering Security

Use zones to provide controlled access to fabric segments and to establish barriers between operating environments. For example, isolate systems with different uses or protect systems in a heterogeneous environment.

Customizing Environments

Use zones to create logical subsets of the fabric to accommodate closed user groups or to create functional areas within the fabric. For example, include selected devices within a zone for the exclusive use of zone members, or create separate test or maintenance areas within the fabric.

Optimizing IT Resources

Use zones to consolidate equipment, logically, for IT efficiency, or to facilitate time-sensitive functions. For example, create a temporary zone to back up non-member devices.

Zoning User’s Guide 1-1

Introducing Zoning

Figure 1-1 below illustrates three zones with some overlap. It also contains devices that are not assigned to a zone, and are thus not active in the fabric if Zoning is enabled.

No zone

Figure 1-1 Fabric with Three Zones

Implementing Zoning

Implementing Zoning simplifies the zoning process in the following ways:

• You can administer Zoning from any switch in the fabric. Co nfig uratio n changes made to one

switch are automatically replicated to all switches in the fabric.

• Zones can be configured dynamically. When configuring new zones:

• Data traffic on ports and devices is idle for a moment, then resumes according to the new

zoning configuration. With hardware WWN zoning and port zoning, Windows NT ports may need to be rebooted to access new devices. With HP-UX, a new disc scan may need to be performed if the zone is altered.

• Data traffic across interswitch links (ISLs) in cascaded switch configurations is not

affected.

• Zoning uses policy-based administration. Because Zoning u ses policy-based adm inistration —

separating zone specification from zone enforcement — you can manage multiple zone configurations and easily enable a specific co nfiguration when it is required. A fabric can store any number of zone configurations; however, only one configuration is active at a time. Because the configurations are pre-determined and stored, a new configuration can be easily enabled.

• Zoning can be configured and administered with either telnet commands or Web Tools.

For information on telnet commands, see the Fabric OS Reference Guide. For i nfo rmat ion on Web Tools, see the Web Tools User’s Guide.

Installing Zoning

A Zoning license can be installed with either:

• Installing Zoning with Telnet Commands on page 2-1

• Installing Zoning from Web Tools on page 2-2

Installing Zoning with Telnet Commands

To install using telnet com mand s, perfo rm th e follo wing steps:

1. Log onto the switch by telnet, see the user’s guide provided with the hardware for details, using an account that has administrative privileges.

Chapter

2. On the command line, enter

licenseAdd “key”

where “key” is the license key in double quotes.

Note: The license key must be entered exactly as given; it is case sensitive.

3. On the command line, enter

licenseShow

to be sure the license has been activated, for example:

admin> licenseShow 9S9RzSebeATAS0k:

2. Enter the switch name or IP address in the Location/Address field.

3. When the Fabric View appears, click on the appropriate switch icon.

4. When the Switch View appears, click the admin button.

5. When the Administration View appears, click the License Admin tab.

6. Enter the license key, and click Add License.

2-2 Zoning User’s Guide

Using Zoning

This chapter explains the concept of zoning and how to use Zoning to partition a fabric into logical groupings of devices.

Understanding Zoning

A zone is a group of fabric-connected devices arranged into a specified grouping. Any device connected to a fabric can be included in one or more zones. Devices within a zone possess an awareness of other devices within the same zone; they are not aware of devices outside of their zone.

Zone members (ports, WWNs, or aliases) are grouped into a zone; in turn, zones are grouped in a zone configuration (a collection of zones). Zones can overlap; that is, a device can belong to more than one zone. A fabric can consist of multiple zones.

A zone configuration can include both hard and soft zones (described below) and there can be any number of zone configurations resident on a switch; however onl y one configuration can be active, that is enabled, at a time. The number of zones allowable is limited only by memory usage.

Chapter

Zone Types

The following list describes the FC Entry Switch 8B, FC Switch 8B, and FC 16B zone types: Port Zone A zone containing members s pecified by switch ports (domain ID, port n umb er),

or aliases of switch ports, only.

WWN Zone A zone containing members specified by device World Wide Name (WWNs), or

aliases of WWNs, only. WWN zones are hardware enforced in the FC Entry Switch 8B, FC Switch 8B, and FC 16B products, and are s oftware enforced in the HP Brocade 2400 and 2800 switches and the FC 6164.

Mixed Zone A zone containing some members specified by WWN and some members

specified by switch port. Mixed zones are software enforced through the fabric name server only. This means that some hosts may need to be rebooted for zoning to take effect.

Zones can be hard (hardware enforced) or soft (advisory). In a hardware enforced zone, zone members can be specified by port number, or by WWN, but not both. A software enforced zone is created when a port member and WWN member are in the same zone.

Zoning User’s Guide 3-1

Using Zoning

Zone Enforcement

Hardware Enforced Zones

In a hardware enforced zone, all zone members are specified as either switch ports or WWN, but n ot both. Any number of ports or WWNs i n the fabric can be configured to the zone. When a zone member is specified by port number or WWN, the individual device port or WWN is included in the zone. If WWNs are used exclusively in a zone, new devices can be attached without regard to physical location. In hard zones, switch hardware ensures that there is no data transferred between unauthorized zone members. However, devices can transfer data between ports within the sa me zone. Consequ ently, hard zoning provides the highest level of security.

Software Enforced Zones

In a software enforced zone, at least one zon e memb er is s pecified b y WWN and

one member is specified as a port. In this way, you have a mixed zone that is software enforced. When a device logs in, it queries the name server for devices within the fabric. If zoning is in effect, only the devices in the same zone(s) are returned. Other devices are hidden from the name server query reply.

Software enforced zones are created when a combination of WWNs and ports are used. When using software enforced zones, the switch does not control data transfer and there is no guarantee of data being transferred from unauthorized zone members. Use software zoning where flexibility and security are ensured by the cooperating hosts.

When zoning is disabled, devices can communicate without regard to zone restrictions. When zoning is enabled, zoning is enforced throughout the fabric and devices can communicate only within their zones.

FC Entry Switch 8B, FC Switch 8B, and FC 16B products can maintain any number of zone configurations; however, only up to one zone configuration can be enabled, or enforced, at a time. Because multiple configurations reside in the switch, you can switch from one configuration to another as events dictate. For example, you can write a script to set up a pre-specified zone configuration to be enabled at certain times of the day; or , in the even t of a disaster , y ou can quickly enable a defined configuration to implement your disaster policy.

Zone configurations can be: Defined This is the complete set of all zone objects that have been defined in the

fabric. When zone objects are defined, the information initially re sides in RAM; it must be saved to ensure that it is saved to flash memory and is not lost during:

• new zone configuration

• power down

• reboot

• fastboot

• power cycles

Effective This is the zone configuration that is enabled (active). It resides in RAM; it

must be saved to ensure that it is not lost during power down. Any changes replicate to all switches in the fabric when the configuration is enabled or saved.
