  • Page 15: Introduction

    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.

  • Page 16

    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.

  • Page 47: Configuring Zones

    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: •...

  • Page 48: Zoning Through A Single Fibre Channel Managed Product

    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.

  • Page 49: Zoning Through A Multiswitch Fabric

    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. Zone 1 Zone 2 Zone 3 Interswitch Link Director Director Director Figure 3–2: Zoning through a multiswitch fabric embedded web server user guide 3–3...

  • Page 50: Controlling Access At The Switch

    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.

  • Page 51: Zoning Concepts

    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).

  • Page 52: Naming Conventions For Zones And Zone Sets

    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. •...

  • Page 53: Using Wwns

    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.

  • Page 54: Default Zone

    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.

  • Page 55: Active Zone Set

    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.

  • Page 56: Merging Zones

    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).

  • Page 57: Configuring, Adding, Or Deleting Zones

    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.

  • Page 58

    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).

  • Page 59: Modify Zone Tab View

    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.

  • Page 60: Configuring Zone Sets

    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.
