Topic Port Fencing Port Mirroring Web Tools and Zoning Licenses Description • 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 only disabled upon detection of a second set of errors, i.e. 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, and 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. Proper behavior of Port Mirroring functionality requires that the entire frame path must contain either only 8Gb ASICs or only 4Gb ASICs. If a frame path contains a mix of 8Gb and 4Gb ASICs, this functionality will not work as intended. With the release of Fabric OS 6.1.x, the WebTools and Zoning licenses are now included in the base firmware. If a licenseshow command is executed, it shows the WebTools and Zoning licenses as Unknown license1 and Unknown license2. This does not indicate any problem, and 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 the selection of passwords with consecutive, 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. • Logs a RASLog message when a 2.x switch joins the fabric. • HA failover and user notification occurs on the 4/256 SAN Director when there is a failed Ethernet chip (oscillator chip). 14
