FOS Migration Considerations This section contains important details to consider before migrating to or from this FOS release. TSBs - Critical Issues to Consider Prior to Installing This FOS Release Technical Support Bulletins (TSBs) are produced to provide detailed information about high priority defects or issues present in FOS releases. The following sections specify all current TSBs that have been identified as being a risk to or resolved with this specific version of Fabric OS.
TSB Summary TSB 2011-108-A Upon upgrading a Fabric switch to v6.4.1. or 6.4.1a, F_Port trunking used to connect any Access Gateways will not be allowed if the Fabric switch does not have a SAO (Server Application Optimization) license installed. This will eventually result in connectivity loss between the AG and switch if attached via F_Port trunks.
If Bottleneck detection feature is currently enabled on the switch running FOS v6.3.x, you must disable it before upgrading to FOS v6.4; otherwise, frame drops may occur due to increased Hot Code Load (HCL) time. 7800 platform and FX8-24 blade must be power cycled after upgrading from FOS v6.3 to FOS v6.4. This is necessary to load the new FPGA image that enables IPv6 capability for FCIP links to 7800 and FX8-24 blade. This step is mandatory even if IPv6 will not be used on the FCIP ports.
supported on version 12.1.5 or later. With JRE 1.7.0 update 51, users could see some browser warning messages that can be ignored. WebTools is supported with Google Chrome browser with FOS v6.4.3f. When launching WebTools on a computer without Internet access, it could take upto 5 minutes to complete because the certicate revocation check performed for the WebTools application takes time to timeout. Users can turn off the certification revocation check on the Java control panel as a workaround.
Supported Products and FOS Interoperability Brocade 7800, DCX and DCX-4S with FCOE10-24 or FX8-24 blades v6.3 and later Brocade DCX and DCX-4S with FC8-64 blade v6.4 Brocade DCX, 300, 5100, 5300 v6.1.0e and later 5 VA-40FC v6.2.1_vfc, v6.2.2, v6.3.1, v6.4 Brocade DCX-4S v6.2.0 and later Brocade DCX with FS8-18 blade(s), Brocade Encryption Switch v6.1.1_enc and later Brocade DCX/DCX-4S/48000 with FA4-18 blade(s), Brocade 7600 v5.2.x or later (DCX requires v6.0.x or later, DCX-4S requires 6.2.

FOS Feature Compatibility in Native Connectivity Modes Some FOS features are not fully supported when operating in the native connectivity modes for deployment with M-EOS based products. All Brocade models that are supported by Fabric OS v6.4 support both interopmodes 2 and 3 with the exception of the Brocade 4100 and 8000 and DCX/DCX-4S with one or more FCOE10-24 blades.
FOS Features (supported in interopmode 0) IM = Interopmode FCIP (VE_Ports) IPFC (IP over FC) M-EOS ALPA 0x13 configuration VE to VEX Port Integrated Routing9 Domain Offset Support 239 Domain Support (available on Mi10k only) Masterless F_PORT Trunking (AG connect to FOS switches only) FC10-6-to-FC10-6 ISL RASLOG Events on duplicate WWNs Virtual Fabrics Logical Fabric using LISLs (XISLs in Base Fabric) Port Fencing Bottleneck Detection Lossless DLS FOS v6.
Other Important Notes and Recommendations Management Server Platform Capability support changes in FOS v6.4 FOS v6.4 no longer automatically enables the Management Server (MS) Platform capability when a switch attempts to join a fabric that has these services enabled. This prevents a FOS v6.4 switch from joining such a fabric, and ISL will be disabled with a RAS log message. To allow a FOS v6.
Differences between the Brocade 7800/FX8-24 platforms and previous generation 7500/FR4-18i platforms include: o On the 7800, the GbE port does not directly correlate to a VE port o On the FX8-24, GbE ports 0-9 or 10GbE port 1 (xge1) correspond to VE ports 12-21, and 10 GbE port 0 (xge0) corresponds to VE ports 22-31 o The CLI syntax for the 7800/FX8-24 varies from the 7500/FR4-18i. Please refer to the Brocade Fabric OS Command Reference document for FOS v6.
When operating in Converged Mode, tagged traffic on the native VLAN of the switch interface is processed normally. The host should be configured not to send VLAN tagged traffic on the switch’s native VLAN. When operating in Converged Mode, tagged frames coming with a VLAN tag equal to the configured native VLAN are dropped. The Converged Network Adapter (CNA) may lose connectivity to the Brocade 8000/FCOE10-24 if the CNA interface is toggled repeatedly over time.
An FCOE10-24 blade installed in the highest numbered slot of a DCX or DCX-4S chassis does not send out FIP unsolicited advertisements. Therefore, it does not support FCoE functionality when installed in this slot. The Brocade 8000 and FCOE10-24 can handle 169 small FCoE frames in bursts. If you are using the Brocade 8000 or FCOE10-24, and you delete a large number of v-ports with HCM, some of the v-ports may not appear to be deleted.
o Maximum of 6 Encryption nodes per Windows/Linux TKLM server. o Maximum of 10 Encryption nodes per AIX TKLM server. o Maximum of 16 tape sessions per Encryption node. o Minimum of 180 second timeout for tape hosts. Disk Encryption Rekey: Configupload/download does not retain the auto rekey value. The first auto rekey after configdownload will occur based on the previously configured key life. The newly configured key life value (as part of configdownload) will be used after the first auto rekey.
For dual LKM configuration on the Brocade Encryption Switch (BES) or a DCX/DCX-4S with FS8-18 blades as the primary and secondary key vaults, these LKM appliances must be clustered (linked). Failure to cluster will result in key creation failure. Otherwise, register only one LKM on the BES/FS818 Encryption Group. Please refer to the Encryption Admin Guide for configuration information. The RKM Appliance A1.6, SW v2.7 is supported.
When disk and tape CTCs are hosted on the same encryption engine, re-keying cannot be done while tape backup or restore operations are running. Re-keying operations must be scheduled at a time that does not conflict with normal tape I/O operations. The LUNs should not be configured with auto rekey option when single EE has disk and tape CTCs.
Users who want to utilize Access Gateway’s Device-based mapping feature in the ESX environments are encouraged to refer to the SAN TechNote GA-TN-276-00 for best implementation practices. Please follow these instructions to access this technote: o Log in to http://my.brocade.com o Go to Documentation > Tech Notes. o Look for the Tech Note on Access Gateway Device-Based Mapping in VMware ESX Server.
Integrated Routing and TopTalkers (Fabric Mode) are not concurrently supported. To use Integrated Routing, be sure to disable Fabric Mode TopTalkers prior to configuring EX_Ports first. Native Connectivity FOS-based platforms operating in interopmodes 2 or 3 should never be deployed in a fabric without at least one M-series switch. FOS switches in interopmode 3 (McDATA Open Fabric Mode) do not support configuration of zoning without an M-series switch in the fabric.
10G Interoperability 10G interop between FC10-6 and McDATA blades is not supported due to a HW limitation, however the FC10-6 is supported in a chassis running in Interopmode 2 or 3 (FC10-6 to FC10-6 connections only). An FC10-6 blade will not synchronize with a McDATA 10G blade. However, the inability to synchronize will not negatively impact the system. Port Fencing The state changes counter used by Fabric Watch in FOS v6.
flow control mode that uses IDLE primitives does not support Brocade frame-based Trunking for devices such as Time Division Multiplexor (TDM.) In order to overcome this limitation and provide support for frame-based Trunking with Extended Fabrics, Fabric OS v6.2.0 and later has been enhanced to support interoperability with these distance extension devices. Fabric OS v6.3.1 allows Extended Fabrics E_Ports to operate in VC_RDY mode using either ARB or IDLE primitives as fill words.
The portCfgFillWord command, applicable to 8G-capable ports, has been enhanced with FOS v6.3.1 and v6.4 to provide two new configuration options (Modes 2 and 3). The available settings include: Mode Link Init/Fill Word Mode 0 – IDLE/IDLE Mode 1 – ARBF/ARBF Mode 2 – IDLE/ARBF Mode 3 – If ARBF/ARBF fails use IDLE/ARBF Although this setting only affects devices logged in at 8G, changing the mode is disruptive regardless of the speed the port is operating at.
Enables serdes tuning mode and sets new serdes values on FC8-16 blades in slot 2 and 7 and on peer ports in the CR4S-8 blade. – reset Clears serdes tuning mode and resets the old serdes values on the FC8-16 blades in slot 2 and 7 and on peer ports in CR4S-8 blade. – show Displays whether the serdes tuning mode is enabled or disabled. – help Displays the serdestunemode command usage.

Closed with Code Change in Fabric OS v6.4.0a Defect ID: DEFECT000298730 Technical Severity: High Summary: A LUN sized > 2TB cannot be configured for encryption with the -newLUN option Symptom: There is a potential for hosts to overwrite encryption metadata for encrypted LUNs where Read Capacity (16) is used to determine max LUN LBA (LUNs greater than 2TB in size). Workaround: Do not configure LUNs for encryption, using the -newLUN option if the LUN size is greater than 2TB.
Closed with Code Change in Fabric OS v6.4.0a Defect ID: DEFECT000281212 Technical Severity: Medium Summary: In AG mode, N-Port failover results in F-Ports with attached hosts getting stuck as G_Port Symptom: F-Ports get stuck as G-Ports after AG N-Port failover.
Closed with Code Change in Fabric OS v6.4.0a Defect ID: DEFECT000290784 Technical Severity: Medium Summary: Abort in Read emulation if Attention status received between status and status accept Symptom: IFCCs during Tape Read processing. Workaround: Disable FICON Emulation Feature: FCIP Function: FCIP I/O Probability: Medium Found in Release: FOS6.3.
Closed with Code Change in Fabric OS v6.4.0a Defect ID: DEFECT000299335 Technical Severity: Medium Summary: FICON emulation, core hangs during error recovery Symptom: After an FCIP link failure, an FFDC will occur and some traffic across remaining FCIP links will continue to be disrupted. Feature: FCIP Function: Emulation Probability: High Found in Release: FOS6.4.0 Defect ID: DEFECT000300065 Technical Severity: Medium Summary: Data Encryption, Manual HA failback command on FOS v6.4.
Appendix: Additional Considerations for FICON Environments This appendix includes supplemental information for users deploying FOS-based platforms in FICON environments. The DCX-4S is only supported for FICON in Brocade Native Mode (interopmode 0) and therefore is not supported for interoperability with M-EOS platforms. Multiple 10 Gb/sec ISLs and FCIP links can load-share between cascaded FICON directors/switches but do not load balance in a FICON configuration.
Area Manageability Comments It is suggested that Port Fencing be used to avoid taking ports down for normal fabric events. The recommended fencing criteria and settings are: Criteria Value ITW (Invalid Transmission Words) 25 CRC (Cyclical Redundancy Check) 3 Protocol Errors 2 State Change 7 Note: In a FICON environment, the time base polling interval MUST be set to one minute for granular control and response. By default, Port Fencing time base is set to one hour.
Interoperability Within a fabric, current major releases will work with previous major releases on the same platform. When cascading switches, it is recommended to keep all switches in the fabric at the same code level. Although not expressly prohibited, having two switches in the same fabric that differ by more than one major FOS release level is not recommended. For example, a switch at FOS v6.4.2a connected to another switch at v6.4.0c is OK. Connecting a switch running FOS v6.4.
