Topic Description Traffic Isolation over FCR • All switches and Fibre Channel Routers both in edge and backbone fabrics must be running Fabric OS 6.1.0 in order to support this feature. • It is essential to have "fail-over" policy enabled in all edge fabrics that are part of the Traffic Isolation Zones, in order for the proper functioning of Traffic Isolation over FCR. FICON CUP Cascading All switches must operate with Fabric OS 6.1.x or later to support this feature. Port Fencing • Port Fencing is only supported on E_Port and F_Port classes. Port Fencing is available with the optional Fabric Watch license. • When the port fencing feature is enabled for ITW or CRC errors, the first set of errors detected on an active link that meet the custom high threshold level set by the user (or the default threshold level) is always ignored to account for expected link transition errors. The port is disabled only upon detection of a second set of errors, that is, the next time the user-set threshold level (or default threshold level) is reached. This prevents a port from being disabled due to normal link transition behaviors. • The default settings for Port Fencing reflect very low thresholds, which may cause fence ports to experience errors. HP recommends increasing these threshold values for use in production environments. Different platforms may require different threshold settings for optimum behavior. Port Mirroring Proper behavior of Port Mirroring functionality requires that the entire frame path must contain either only 8-Gb ASICs or only 4-Gb ASICs. If a frame path contains a mix of 8-Gb and 4-Gb ASICs, this functionality will not work as intended. Web Tools and Zoning Licenses With the release of Fabric OS 6.1.x, the Web Tools and Zoning licenses are now included in the base firmware. If a licenseshow command is executed, it shows the Web Tools and Zoning licenses as Unknown license1 and Unknown license2. This does not indicate a problem All the functionality provided by the licenses in the past firmware releases will be present with 6.1.x. Additional Fabric OS 6.1.x enhancements Additional Fabric OS 6.1.x enhancements include: • Provides new Fabric OS commands to rename an alias, a zone, and a zone configuration: • Zone -copy-Copies the zone object to a new zone object. • Zoneobjectrename-Renames the zone object. • Detects a corrupted zone configuration [under /etc/fabos/zone*] and handles it gracefully instead of rebooting. The switch also logs the error in RASLOG. • Adds a new command that provides both the WWN (world wide name) and serial number of the switch. Adds an -sn option to display the serial number. For example, wwn -sn returns both the WWN and serial number data. • Provides additional information on a faulty port in Fabric Watch to aid in troubleshooting. • Enables use of passive FTP to download firmware. • Enables the user to specify a quality password policy that prevents selecting passwords with con- secutive, identical characters. • Uses multiple NTP servers with the tsclockserver command for redundancy. For example, if one site NTP server fails (DR scenario), there is a backup that can be reached by the switches. 16
