Chapter Introducing Zoning 1 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.
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. Configuration changes made to one switch are automatically replicated to all switches in the fabric.
Chapter Installing Zoning 2 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 commands, perform the following 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. 2.
2 Installing Zoning Installing Zoning from Web Tools To install using Web Tools, perform the following steps: 2-2 1. Launch your browser. 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.
Chapter Using Zoning 3 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.
3 Using Zoning Zone Enforcement Hardware Enforced Zones In a hardware enforced zone, all zone members are specified as either switch ports or WWN, but not both. Any number of ports or WWNs in 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.
Using Zoning Saved 3 This is the zone configuration that was last saved. It resides in flash memory and it is persistent. In Figure 3-1, the defined and effective configurations are saved to flash: Defined Effective Disabled Saved Disable Path Enable Path Config 1 Config 1 Config 2 Config 3 Config 4 Config 5 Defined Config 1 Config 2 Config 3 Config 4 Config 5 Effective Config 1 Save Path Figure 3-1 Enabling a Zone Configuration In Figure 3-2, Config 5 is defined (created).
3 Using Zoning In Figure 3-2, zone configurations are defined, enabled and saved to flash: Defined Enabled Enable Config1 Saved . . .then Save to Flash Config1 Config1 Config2 Config2 Config3 Config3 Config4 Config4 Config5 (new) Save directly to Flash Enforced Figure 3-2 • Saving a Zone Configuration Disabling it. This deletes the effective configuration and saves the defined to flash. There is no effective configuration in the flash at this point.
Using Zoning 3 Implementing Zoning Zoning can be implemented and administered from any switch in the fabric. When a change in the configuration is saved, enabled or disabled per the transactional model, it is automatically distributed to all switches in the fabric. For that reason, Zoning requires that all switches in the fabric have an active Zoning license. Zoning is a standard feature on the FC Switch 8B and FC 16B. Zoning is an optional feature on the FC Entry Switch 8B.
3 Using Zoning A zone is a group of devices that can communicate with each other. Zone membership can include ports, WWNs, or aliases, or any combination of these. A device can be included in more than one zone. To define a zone, specify the list of members to be included and assign a unique zone name; the zone name must be a unique alpha-numeric string beginning with an alpha character. The underscore character ( _ ) is allowed and zone names are case-sensitive.
3 Using Zoning The switch configuration file can also be uploaded to the host for archiving and it can be downloaded from the host to all switches in the fabric. Adding a Switch When a new FC Entry Switch 8B, FC Switch 8B, or FC 16B is added to the fabric, it automatically takes on the zone configuration information from the fabric. To add the new switch, attach the E_ports and the new switch is incorporated into the fabric and the enabled zone configuration.
3 Using Zoning In the simplest case, where both fabrics have identical zone configuration data and the same configuration enabled, the fabrics join to make one larger fabric with the same zone configuration enabled across the new fabric. If the fabrics have different zone configuration data, the two sets of zone configuration data are merged if possible. If not possible, the ISL is segmented.
Chapter Zoning and Partnering with QuickLoops 4 In addition to zoning fabrics, explained in Chapter 3, Using Zoning, Zoning can also be used to create QuickLoop partnerships and to zone QuickLoops. For JBODs, private hosts, and other private loop devices, QuickLoop allows arbitrated loops to be attached to a fabric. For example, the QuickLoop and Zoning combination can allow a private host to participate in a Storage Area Network (SAN).
4 Zoning and Partnering with QuickLoops In QuickLoop zoning, devices within a QuickLoop can be partitioned off within that QuickLoop to form QuickLoop zones; in other words, a QuickLoop Zone is a subset of a QuickLoop and can include only QuickLoop devices.
Zoning and Partnering with QuickLoops 4 QuickLoop zone members are designated by looplet (port number), or by Arbitrated Loop Physical Address (AL_PA). There are 126 unique AL_PAs per QuickLoop; therefore, a QuickLoop zone can contain no more than 126 devices. Configuring QuickLoop Zones To configure QuickLoop Zoning, perform the following: 1. Establish QuickLoop partnerships 2. Create a QuickLoop 3. Define QuickLoop zone 4. Define QuickLoop zone configuration 5.
4 Zoning and Partnering with QuickLoops To define a QuickLoop zone, specify the list of members to be included and assign a unique zone name. A QuickLoop zone name must be a unique alpha-numeric string beginning with an alpha character. The underscore character ( _ ) is allowed and zone names are case-sensitive. For example, Zone1 is not the same name as zone1. To create a QuickLoop zone, specify QuickLoop zone members by looplet, by AL_PA, or by combination of the two.
Chapter Detailed Zoning Examples 5 The following examples illustrate setting up a zone configuration. Note that changes have been saved periodically to facilitate switching from one configuration to another. In addition to the periodic saves, the cfgShow command has been issued to display current status to verify that changes have been processed. Set Up a Fabric Zone Configuration A configuration named “cfg1” is established by using the cfgCreate command.
