• 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 NTP server fails (DR scenario), there is a backup that switches can access. • Logs a RASLog message when a 2.x switch joins the fabric. • High availability failover and user notification occur on the 4/256 SAN Director when there is a failed Ethernet chip (Oscillator chip). • Advanced Zoning with WebTools licenses are no longer necessary, starting with Fabric OS 6.1.x. These features are automatically enabled on all products running Fabric OS 6.1.x or later. 8-Gb Link Init and fill words This section describes the portCfgfillWord command that was added beginning with Fabric OS 6.1.2. Overview The FC Physical Interfaces (FC-PI) standard defines the requirements for a physical layer. It considers all aspects of transmit, receive, and cable-plant performance requirements for optical and electrical links. The FC-PI standard has been modified to support new physical-layer variants that operate at higher data rates than those specified in FC-PI-2. The standard enables interoperability of transmitter devices, receiver devices, interconnects, and components from different manufacturers. New variants include support for an 800 MB/s data rate. The previous implementation by Brocade was to use IDLE for Link Init and as fill words, which works for 1-Gb, 2-Gb, 4-Gb, and most 8-Gb devices. However, some of the new 8-Gb devices have problems with the IDLE/IDLE sequence at 8 Gb. 8-Gb switches, HBAs, and smaller mid-range 8-Gb storage devices are using the IDLE/IDLE sequences without any problems. Some of the new 8-Gb devices require that the ARB (FF)/ARB (FF) sequence have successful Link Initialization. Brocade has developed an implementation of ARB (FF)/ARB (FF) for initialization and fill words. The portcfgfillword command, first introduced in Fabric OS 6.1.2, configures the ARB(FF)/ARB(FF) implementation. portCfgFillWord command The portCfgFillWord command configures the fill word for a single 8-Gb FC port. • Description: Use the portCfgFillWord 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. The configuration is stored in nonvolatile memory and is persistent across switch reboots and power cycles. • Notes: Use the portCfgShow command to display user-configured fill-word settings. The execution of this command is subject to any Administrative Domain restrictions. • Syntax: portcfgfillword [slotnumber/]portnumber, mode • Operands • slotnumber-For blade systems only, specifies the slot number of the port to be configured, followed by a slash (/). • portnumber-Specifies the number of the port to be configured, relative to its slot for blade systems. Use the switchShow command to display a list of valid ports. HP StorageWorks Fabric OS 6.1.2a release notes 19
