Description
The portCfgTrunkPort <port>, 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.
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.
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 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 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.
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.
