the output I just pasted is from a problematic server which has 2 nics I was using a "TEST" server which has just one nic in the 10.10.20.x segment but to be realistic I requested access to one of the production server having the issue... since it was out customer who found the issue
this server is 10.10.10.23 - Production IP
10.10.20.11 - Backup IP
yes both ends have etherchannels I mean Power 701 (AIX-TSM) is using 2 adapters for etherchannel and yes I used smitty vlan to create VLAN 500 for backups
for VIO in the p260 - pureflex - which hosts the PRODuction LPARs is using etherchannel and vlans are create as well

fipvlan
FIPVLAN(8) Open-FCoE Tools FIPVLAN(8)
NAME
fipvlan - Fibre Channel over Ethernet VLAN Discovery
SYNOPSIS
fipvlan [-c|--create] [-s|--start] [-m|--mode fabric|vn2vn] interfaces
fipvlan -a|--auto [-c|--create] [-d|--debug] [-s|--start] [-m|--mode fabric|vn2vn] [-l|--link-retry count]
fipvlan -h|--help
fipvlan -v|--version
DESCRIPTION
The fipvlan command performs Fibre Channel over Ethernet (FCoE) Initialization Protocol (FIP) VLAN Discovery over Ethernet interfaces.
fipvlan can be used as a diagnostic tool to determine which VLANs have FCoE services available on a network, prior to configuring VLAN
interfaces and the Open-FCoE initiator. fipvlan can also be used to create VLAN interfaces as they are discovered, and to start the
Open-FCoE initiator. The --create and --start options are primarily intended to be used as part of an Open-FCoE boot solution. FCoE
instances started in this way cannot be destroyed or reset by fcoeadm.
fipvlan takes a list of network interface names to run the VLAN discovery protocol over, or the --auto option to use all available Ethernet
interfaces.
fipvlan will enable any interface which is found disabled. If no response is received on that interface it will be shutdown again when
fipvlan terminates.
OPTIONS
-a, --auto
Use all Ethernet interfaces currently available
-c, --create
Create network interfaces for discovered FCoE VLANs. If a VLAN device already exists for a discovered VLAN, a new VLAN device will not
be created.
-d, --debug
Enable debugging output
-s, --start
Start the Open-FCoE initiator on discovered FCoE VLANs
-m, --mode
fabric|vn2vn Specify whether VLAN discovery is performed in the default fabric mode, or in VN2VN mode.
-f, --suffix suffix
Append the specified string suffix to VLAN interface names.
-l, --link-retry count
Retry check for link up to count times. The link state is checked every 500 ms. The default number of retries is 20.
-h, --help
Display a help message with basic usage instructions
-v, --version
Display the fipvlan version string
VLAN NAMING CONVENTIONS
If a new VLAN device is created, it will have the name dev.vlan; where dev is the name of the Ethernet parent device and vlan is the
discovered VLAN ID number. An optional suffix may be appended to this with the the -f command line option.
EXAMPLES
Display all discoverable VLANs with FCoE services
fipvlan --auto
Discover FCoE VLANs on interface eth2, create VLAN devices and start the Open-FCoE initiator
fipvlan --create --start eth2
In this example if FCoE services were available on VLAN 101 of network interface eth2, then a VLAN interface eth2.101 would be created and
used as the parent device for the initiator.
