1 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.
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).
Introduction Viewing the User Interface When the EWS interface opens, the default display is the View page. Figure 1–1 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 — Configure — At the Configure page, the Ports (default), Director or Switch, Management, Zoning, and User Rights task selection tabs display. — 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.
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.
Introduction 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.
Introduction 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, Configuring the Product. 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.
Introduction 4. After a connection is made between the web browser and the product, the Enter Network Password dialog box displays as shown in Figure 1–2. Figure 1–2: Enter Network Password dialog box 5. Type the user name and password. 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.
2 Configuring the Product This chapter describes how to configure an HP product using the EWS interface. These procedures can be used to configure a product after installation and as changes are needed.
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 the Product Figure 2–1: 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. The port name should characterize the device to which the port is attached. 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.
Configuring the Product 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.

3 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.
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.
Configuring Zones Figure 3–2 illustrates how zones can consist of ports and/or devices installed on ports in three managed products in a multiswitch fabric.
Configuring Zones Controlling Access at the Switch A World Wide Name (WWN) 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. NOTE: This WWN Binding feature can be configured through the HP HAFM Product Manager but not through the EWS.
Configuring Zones 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.
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.
Configuring Zones 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.
Configuring Zones 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.
Configuring Zones • 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.
Configuring Zones • 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). Table 3–1: Merging Zones Fabric A Fabric B Result Not zoned Not zoned Fabrics join successfully. The new fabric remains not zoned.
Configuring Zones 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.
Configuring Zones • 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. 4.
Configuring Zones Figure 3–4: Modify Zone tab view 6. Add or delete zone members as follows: • Add member by attached node WWN — Choose the WWN of an attached device (node) from the Attached Node World Wide Name drop-down list and click the adjacent Add Member button. The device is added to the zone. (This option is valid for local devices only.) • Add member by WWN — Type the WWN of a device in the World Wide Name field and click the adjacent Add Member button. The device is added to the zone.
Configuring Zones • Add member by domain ID and port number — Type the domain ID (1 through 31) of the switch in the Domain ID field, type the switch port number to which a device is attached, and click the adjacent Add Member button. The device attached to that port is added to the zone. • Delete a member — To delete a zone member, click the Delete button adjacent to the configured zone member (WWN or domain ID and port number) at the bottom of the page. A confirmation dialog box displays.
Configuring Zones Figure 3–5: Zone Set tab view 3. Click Save and Activate Zoning Configuration. After the zone set name is validated, a confirmation dialog box displays. 4. Click OK to save and activate the new zone set. The message Your changes to the Zoning configuration have been successfully activated displays. Note the following: • Rename zone set — To rename a zone set, type the new name in the Zone Set Name field. Click Rename Zone Set. The new zone set name is validated and changed.
