Table 87 F_Port masterless trunking considerations (continued) Category Description portCfgTrunkPort , 0 switchCfgTrunk 0 The portCfgTrunkPort , 0 command will fail if a Trunk Area is enabled on a port. The port Trunk Area must be disabled first. The switchCfgTrunk 0 command will fail if a port has TA enabled. All ports on a switch must be TA-disabled first. Port swap Trunk master Fastwrite FICON When you assign a Trunk Area to a trunk group, the Trunk Area cannot be port swapped; if a port is swapped, you cannot assign a Trunk Area to that port. No more than one trunk master in a trunk group. The second trunk master will be persistently disabled with reason "Area has been acquired". When you assign a Trunk Area to a trunk group, the trunk group cannot have Fastwrite enabled on those ports; if a port is Fastwrite-enabled, the port cannot be assigned a Trunk Area. FICON is not supported on F_Port trunk ports. However, FICON can still run on ports that are not F_Port trunked within the same switch. HP StorageWorks SAN Director 48 Port 4Gb FC Blade HP StorageWorks 4/256 SAN Director 16 Port 4Gb Blade Access Gateway mode Trunking PID format F_Port masterless trunking is supported only on ports 0-15 on the HP StorageWorks SAN Director 48 Port 4Gb FC Blade. If an HP StorageWorks 4/256 SAN Director 16 Port 4Gb Blade (Electron) has the Trunk Area enabled on ports 16-31 and the blade is swapped with an HP StorageWorks SAN Director 48 Port 8Gb FC blade, the Trunk Area ports will be persistently disabled. You can run the portTrunkArea command to assign a Trunk Area on those ports. Does not support F_Port trunking. It supports only N_Port trunking in AG mode. You must first enable Trunking on the port before the port can have a Trunk Area assigned to it. F_Port masterless trunking is supported only in the CORE PID format. Long distance Long distance is not allowed on F_Port trunks, which means a Trunk Area is not allowed on long-distance ports; you cannot enable long distance on ports that have a Trunk Area assigned to them. Port mirroring configdownload Port mirroring is not supported on Trunk Area ports or on the PID of an F_Port trunk port. If you enter the configDownload command for a port configuration that is not compatible with F_Port trunking, and the port is Trunk Area-enabled, the port will be persistently disabled. ICL Port AD Note: Configurations that are not compatible with F_Port trunking are long distance, port mirroring, non-CORE_PID, and Fastwrite. F_Port trunks are not allowed on Inter-Chassis Link (ICL) Ports. The portTrunkArea command does not allow it. You cannot create a Trunk Area on ports with different Admin Domains. You cannot create a Trunk Area in AD255. Fabric OS 6.2 administrator guide 447
