Access Gateway trunking

PWWN The entire Trunk Area trunk group share the same Port WWN
within the trunk group. The PWWN is the same across the F_Port
trunk that will have 0x2f or 0x25 as the first byte of the PWWN.
The TA is part of the PWWN in the format listed in Table 7 on
page 26.
Downgrade You can have trunking on, but you must disable the trunk ports
before performing a firmware downgrade.
Note: Removing a Trunk Area on ports running traffic is disruptive.
Use caution before assigning a Trunk Area if you need to
downgrade to a firmware earlier than Fabric OS v6.1.0.
Upgrade No limitations on upgrade to Fabric Os v6.1.0 if the F_Port is
present on switch. Upgrading is not disruptive.
HA Sync If you plug in a standby-CP with a firmware version earlier than
Fabric OS v6.1.0 and a Trunk Area is present on the switch, the CP
blades will become out of sync.
Port Types Only F_Port trunk ports are allowed on a Trunk Area port for Fabric
OS v6.1.0. All other port types that include F/FL/E/EX are
persistently disabled in Fabric OS v6.1.0.
Default Area Port X is a port that has its Default Area the same as its Trunk
Area. The only time you can remove port X from the trunk group is
if the entire trunk group has the Trunk Area disabled.
portCfgTrunkPort <port>, 0 portCfgTrunkPort <port>, 0 will fail if a Trunk Area is enabled on a
port. The port must be Trunk Area disabled first.
switchCfgTrunk 0 switchCfgTrunk 0 will fail if a port has TA enabled. All ports on a
switch must be TA disabled first.
Port Swap When you assign a Trunk Area to a trunk group, the Trunk Area
cannot be port swapped; if a port is swapped, then you cannot
assign a Trunk Area to that port.
Trunk Master No more than one trunk master in a trunk group. The second
trunk master will be persistently disabled with reason "Area has
been acquired”.
Fast Write When you assign a Trunk Area to a trunk group, the trunk group
cannot have fast write enabled on those ports; if a port is fast
write enabled, the port cannot be assigned a Trunk Area.
FICON 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.
FC8-48 and FC4-48C blades F_Port masterless trunking is supported on ports 16-43 on the
FC8-48 blade. On the FC8-48 and FC4-48C blades F_Port
trunking supported only on ports 0 - 15.
FC4-32 blade If an FC4-32 (Electron) blade has the Trunk Area enabled on ports
16 - 31 and the blade is swapped with an FC4-48C and FC8-48
blade, the Trunk Area ports will be persistently disabled. You can
run the porttrunkarea command to assign a Trunk Area on those
ports.
Trunking You must first enable Trunking on the port before the port can
have a Trunk Area assigned to it.
