  • Page 6 NOTE: Advanced Compression is supported only with FOS 6.3.0a and later. Adaptive Rate Limiting (ARL)—The DC SAN Director Multiprotocol Extension Blade and 1606 Extension SAN Switch allow an FCIP tunnel connection to dynamically change the rate at which the tunnel transmits data through the TCP connections. ARL uses the information from the TCP connections to determine and adjust the rate limit for the FCIP tunnel dynamically.

  • Page 7: Optionally Licensed Software

    CEE/FCoE features 802.1x defines a client/server-based authentication protocol for port access control. It prohibits unknown/unauthorized clients from connecting to an Ethernet network through publicly accessible ports. The authentication server component of the system authenticates each client device or host connected to an authentication-enabled network port. Until the client is authenticated, 802.1x allows only the authentication protocol traffic (EAPOL) on the connected port.
  • Page 8 only 8 links on an ICL port.) This license is available on the DC04 SAN Director and DC SAN Backbone Director platforms only. It replaces the original ICL license for the DC04 SAN Director and is new for the DC SAN Backbone Director. Adaptive Networking—Ensures high-priority connections and obtains the network resources neces- sary for optimum performance, even in congested environments.

  • Page 9: Temporary License Support

    IMPORTANT: Most 2408 FCoE Converged Network Switch units shipped with FOS 6.1.2_cee1 did not include this license and must have it installed before upgrading to FOS 6.3.0. Failure to do so will result in the disabling of FC ports after the upgrade. Contact HP Support to obtain this license key if your 2408 switch does not already have it installed.

  • Page 19: Important Notes

    Important notes This section contains information that you should consider before you use this FOS release. DCFM compatibility FOS 6.3.0b is fully compatible with DCFM 10.3.x management software. DCFM is a comprehensive SAN management application that enables end-to-end management of HP B-series data center fabrics. It is the next-generation product and the successor to existing B-series management products, including HP StorageWorks Fabric Manager (FM) and Enterprise Fabric Connectivity Manager (EFCM).

  • Page 20: Webtools Compatibility

    M-EOS-based platforms must operate with M-EOS 9.8.1 or later for McDATA Fabric Mode (in- teropmode 2), or M-EOS 9.9.0 or later for Open Fabric Mode (interopmode 3). WebTools compatibility FOS 6.3 is supported with JRE 1.6.0 Update 13. If the JRE 1.6.0 version is not Update 13, the DCFM server/client and B-series Element Manager (WebTools) crashes on launch.

  • Page 23: Firmware Upgrades And Downgrades

    Firmware upgrades and downgrades Upgrading to FOS 6.3.0b is allowed only from FOS 6.2.0a or later. The policy to support one-level migration only, which began with FOS 6.0.0, provides more reliable and robust migrations. By having fewer major changes in internal databases, configurations, and subsystems, the system can perform the upgrade more efficiently, ensuring a truly seamless and nondisruptive process for the fabric.
  • Page 24 NOTE: With the introduction of FOS 6.1.1, certain features and functions were removed from WebTools (resident in the firmware) and migrated to the DCFM management application. This has been carried forward to FOS 6.2.x and later. HP recommends that before upgrading to FOS 6.2.x or later, if you are not running DCFM on your fabric, you review the WebTools functionality moved to DCFM”...
  • Page 25 When additional circuits (and the network bandwidth provided by those circuits) are added to an already active tunnel, there is a short period where some frame loss can occur due to the process to refresh the internal FC frame routing tables in the switch. Therefore, additional circuits should be added only during low I/O periods using the FCIP tunnel being modified.
  • Page 26 The CLI syntax for the 1606 Extension SAN Switch/DC SAN Director Multiprotocol Extension Blade varies from the 7500/FR4-18i. See the Brocade Fabric OS Command Reference document for FOS 6.3 for details. Both ends of a tunnel must be identically configured for the Compression, FastWrite, and Tape Pipeline options.
  • Page 27 HP recommends that Spanning Tree Protocol and its variants be disabled on CEE interfaces that are connected to a server. The Fabric Provided MAC Address (FPMA) and Fibre Channel Identifier (FCID) assigned to a VN_Port cannot be associated with any front-end CEE port on which the FLOGI was received. LLDP neighbor information may be released before the timer expires when DCBX is enabled on a CEE interface.

  • Page 28: Virtual Fabrics

    Virtual Fabrics On VF-capable platforms, the VF feature (initially supported with FOS 6.2.0a) must be enabled in order to utilize the related capabilities, including logical switches and logical fabrics. When creating logical fabrics that include switches that are not VF-capable, it is possible to have two logical switches with different FIDs in the same fabric.
  • Page 29 NOTE: After upgrading to this firmware release, if users want to enable the Adaptive Networking QoS feature on 4-Gb platforms and on the Extended Fabrics E_Ports on both 4-Gb and 8-Gb platforms, they must do so explicitly through the available user interfaces. QoS is supported on switches in Access Gateway mode with FOS 6.3.0x.

  • Page 30: Integrated Routing

    Integrated routing To allow HCL on an 8/40 SAN Switch when using Integrated Routing, the edge switch connected to the 8/40 SAN Switch must be running FOS 6.1 or later. 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).
  • Page 31 FICON For the DC SAN Backbone Director, FICON CUP is not allowed with a 48-port blade in the Default Logical Switch. All ports on a 48–port blade must be assigned to a user-defined Logical Switch to use them in a FICON CUP enabled switch. If CUP is enabled in the DLS and any ports on a 48-port blade are assigned to the DLS, all ports on that blade will be persistently disabled.
  • Page 32 As a best practice for deploying Fabric OS switches and directors into a FICON environment, verify the Fabric OS version shipped with the most current Fabric OS recommendation. HP Manageability recommends that you update all Fabric OS switches and directors to the same Fabric OS levels for production.

  • Page 33: Port Mirroring

    Port Mirroring On the 8/80 SAN Switch, the Port Mirroring feature has a limitation where all port mirror resources must remain in the same ASIC port group. The resources are the configure mirror port, Source Device, and Destination Device or ISL, if the Destination Device is located on another switch. The ASIC port groups are 0-15, 16-31, 32-47, 48-63, and 64-79.
  • Page 34 trunking with Extended Fabrics, FOS 6.2.x and later has been enhanced to support interoperability with these distance extension devices. FOS 6.3.0 and later allows Extended Fabrics E_Ports to operate in VC_RDY mode using either ARB or IDLE primitives as fill words. This allows frame-based trunking to be supported on Extended Fabrics E_Ports even when IDLE primitives are configured for these ports when operating in native VC_RDY mode.
  • Page 35 portCfgFillWord command The portCfgFillWord command configures the fill word for a single 8-Gb FC port. Syntax: portcfgfillword [slotnumber/]portnumber, mode 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.

    Miscellaneous After changing domain offset followed by issuing an hafailover command on a DC SAN Backbone Director, DC04 SAN Director, or 4/256 SAN Director running FOS 6.3 in interopmode 2, the console log may generate continuous Unknown LSR type messages. You must either reboot the switch or issue another hafailover command to terminate the messages.

  • Page 39 An exception to this LUN configuration process: If the LUN was previously encrypted by the HP Encryption Switch or HP Encryption Blade, the LUN can be added to the CTC with the –encrypt and –lunstate =“encrypted” options. LUN configurations must be committed to take effect. No more than 25 LUNs can be added or modified in a single commit operation.
  • Page 40 of a security compromise. When disabling the encryption capabilities of the EE using the noted commands, the EE should not be hosting any CTCs. Ensure that all CTCs hosted on the HP Encryp- tion Switch or HP Encryption Blade are either removed or moved to a different EE in the HA Cluster or EG before disabling the encryption and security capabilities.
  • Page 41 In a DC SAN Director or DC04 SAN Director with FOS 6.3.0 and DC Switch encryption FC blades installed, you must set the quorum size to zero and disable the system card on the blade prior to downgrading to a FOS version earlier than 6.3.0. The System Card feature requires DCFM 10.3.0 or later.
  • Page 42 In an environment with a mixed firmware version (FOS 6.2.x + 6.3.0) Encryption Group, the I/O link state reported for FOS 6.2.x nodes is unreachable. During a rolling upgrade from FOS 6.2.0x to 6.3.0, you should see the I/O link status reported as Unreachable when the cryptocfg –show -loc command is invoked.
  • Page 43 NOTE: When configuring multipath LUNs, care should be taken to add LUN 0 on all of the paths, subject to the following considerations: • If LUN 0 presented by the back-end target is a controller LUN (not a disk LUN; that is, not visible in the discoverLUN output), add LUN 0 to the container as a clear text LUN.
