Management Server Registered Node ID (RNID), Link Incident Record Registration
(LIRR), and Query Security Attributes (QSA) Extended Link Service
Requests (ELSs) are not supported on F_Port trunks.
Trunk area The port must be disabled before assigning a Trunk Area on the
Edge switch to the port or removing a Trunk Area from a trunk
group.
You cannot assign a Trunk Area to ports if the standby CP is
running a firmware version earlier than Fabric OS v6.2.0.
PWWN The entire Trunk Area trunk group shares 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 9 on
page 59.
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 v7.0.0 if the F_Port is
present on the 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. All other
port types that include F/FL/E/EX are persistently disabled.
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.
