    signing individual ports to a logical switch. Each logical switch is managed as a completely inde- pendent layer 2 Fibre Channel switch, and can be deployed in independent fabrics known as logical fabrics. VF allows the user to create a special logical switch known as the base switch, which is used for connectivity to other base switches and also as a backbone fabric for FCR.

  • Page 6: Optionally Licensed Software

    The portBeacon CLI command has been added in Fabric OS 6.2.1. It allows individual ports to be identified by enabling a special LED function. The portBeacon command has the following characteristics: Function: Sets port beaconing mode on or off. Syntax: portbeacon - mode [slot]/port Description: Enables or disables port beaconing mode on a specified port.

    NOTE: The encryption switch and encryption blade are unique products compared to standard Fibre Channel switches. HP highly recommends that you read the Fabric OS Encryption Administrator's Guide before configuring these products in any fabric. Supported product models The following product models can be upgraded to Fabric OS 6.2.1: HP StorageWorks 4/8 SAN Switch and 4/16 SAN Switch (Brocade 200E) HP StorageWorks 4/32 SAN Switch (Brocade 4100) HP StorageWorks 4/32B SAN Switch (Brocade 5000)

    Important notes This section contains information that you should consider before you use this Fabric OS release. DCFM compatibility Fabric OS 6.2.1 is fully compatible with DCFM 10.1.x management software. DCFM is a comprehensive SAN management application that enables end-to-end management of HP B-series Data Center Fabrics.

    Fabric OS feature compatibility in native connectivity modes Some Fabric OS features are not fully supported when operating in the native connectivity modes for deployment with M-EOS-based products. All HP StorageWorks models supported by Fabric OS 6.2.1 support both interopmodes 2 and 3, with the exception of the 4/32 SAN Switch. NOTE: HP may not support all of these switches in this mode.

    NOTE: With the introduction of Fabric OS 6.1.1, certain features and functions were removed from Web Tools (resident in the firmware) and migrated to the Data Center Fabric Manager (DCFM) management application. This has been carried forward to Fabric OS 6.2.x. HP recommends that before upgrading to Fabric OS 6.2.x or later, if you are not running DCFM on your fabric, you review the Web Tools functionality moved to...

    tachometer. This situation leads to Fabric OS falsely reporting the fan/power supply as faulty, which could lead to unnecessary return of fan/power supply assemblies. This issue can be avoided by connecting the power cord to the fan/power supply and external power prior to seating it in the switch, then turning on the power switch immediately after insertion.

    the QoS model. If the switch is rebooted, 28 of 32 ports will come up in QoS mode; the last four ports will come up in buffer-limited mode. Workarounds include disabling long distance configur- ation for these ports or explicitly disabling QoS on other ports, freeing up buffers for the last four ports.

  • Page 25: Access Gateway

    Integrated Routing EX_Ports are supported only in the base switch on a switch with VF enabled. To test Integrated Routing functionality, first disable the VF feature (fosconfig --disable vf). Integrated Routing and Top Talkers cannot run concurrently in Fabric OS 6.2.x. To use Integrated Routing, be sure to disable Top Talkers before configuring EX_Ports.

    VF must be enabled on the chassis, and loop devices can be attached only to ports on a 48-port blade assigned to a non-default logical switch operating with the default 10-bit addressing mode. (Loop devices may not be in the default Logical Switch.) A maximum of 144 ports can be used for connectivity to loop devices in a single logical switch in a chassis.

    Description: Use this command to configure the fill word for an 8-Gb FC port. (It does not apply to a non-8-Gb FC port.) This command disables and re-enables the port; the port comes online with the new fill-word setting. The configuration is stored in nonvolatile memory and is persistent across switch reboots and power cycles.

    HP recommends using DCFM for managing the following environments: pure FOS based fabrics, mixed FOS and M-EOS fabrics where the FOS switch/director is the seed switch. EFCM is the recommended management software for M-EOS only fabrics when a FOS switch or director can not be used as the seed switch.

    If a port card is removed from a system with Virtual Fabrics enabled and replaced by a port card with fewer ports, the missing ports will not be able to be removed, which results in configuration change problems. To prevent this, the ports should be re- moved from the Logical Switch to which they are Serviceability assigned prior to the card being removed.
