Faulty SFPs FC Fast Write Web Tools External port with a faulty SFP will be disabled, then enabled once good SFP is inserted. However, port will still show as faulty even though it is healthy. To get the correct "healthy" indication, after enabling the port with the good SFP, remove and re-insert it and the port will then show as healthy. Note the following important information when using FC Fast Write: • Only World Wide Name (WWN) zone (including normal zone and FC Fast Write zone) is supported on FC Fast Write enabled port. • Only single device loop port is supported. • NPIV (example Access Gateway) port is not supported. • FCR backbone devices are not supported. That is FC Fast Write should not be enabled on backbone devices. • FCR edge to edge support is limited by all the target devices on given edge fabric that host talks to should be connected to a 400 MP Router or B-Series MP Router Blade in FC Fast Write mode. FC Fast Write should not be enabled on ports when testing the remote mirror application. • When a very high volume of traffic is being sent by host, FC Fast Write IOs may time out and frame may be dropped. • Within the context of FC Fast Write, L_Port is not supported in Fabric OS 5.3.0. When the regional language is set to anything other than English, Brazilian Portuguese, French, German, Italian, Japanese, Korean, Traditional Chinese, Simplified Chinese or Spanish, Web Tools may not finish loading when connecting to a switch running FOS 5.3.0, 5.3.0a or 5.3.0b. The Switch Explorer progress bar hangs while initializing switch details. This problem is overcome by changing the regional settings for the operating system to English and re-loading Web Tools. Additional Fabric OS 5.3.0 enhancements Additional Fabric OS 5.3.0 enhancements include: • Provides new Fabric OS commands to rename an alias, a zone and a zone configuration. • Detects and handles a corrupted zone configuration [under /etc/fabos/zone*] gracefully instead of rebooting. The switch also logs the error in RASLog. • Adds a new command that provides both the WWN and serial number of the switch. • Provides additional information on a faulty port in Fabric Watch to aid in troubleshooting. • Enables use of passive FTP to download firmware. • Enables the customer 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). Additional Web Tools 5.3.0 enhancements Additional Web Tools 5.3.0 enhancements include: • Provides individual error counters for FC ports from Port admin. • Provides SFP TX/RX power information in DB level from Port admin from Web Tools. • Provides the Clear Counter feature to reset all counters. • Provides ability to clear 400 MP Router or B-Series MP Router Blade GE port Error counters using portStatsClear CLI command. 16
