I found the problem...
I was configuring the controllers to act as a load balancing etherchannel controller. This normally would not be a problem, but I had each NIC connected to a different switch.
I removed the Etherchannel adapter and recreated a new one with a primary/backup failover configuration and it is working fine now.

I have a server with multiple network interfaces. 2 of these interfaces, lets say en2 and en6 make up an etherchannel interface, which let's say en8.
when I run the command
lsattr -El ent8
I can see the designated primary and backup interfaces as ent6 and ent2, in the given order. But... (10 Replies)

4 x 1Gbit port ethernet adapter is dedicated to vios. 8023ad etherchannel is created using those 4 ports. Etherchannel adapter is shared to lpars using SEA.

eshconfig
ESHCONFIG(8) BSD System Manager's Manual ESHCONFIG(8)
NAME
eshconfig -- configure Essential Communications' HIPPI network interface
SYNOPSIS
eshconfig [-estx] [-b bytes] [-c bytes] [-d filename] [-i usecs] [-m bytes] [-r bytes] [-u filename] [-w bytes] [interface]
DESCRIPTION
eshconfig is used to configure device-specific parameters and download new firmware to the Essential Communications RoadRunner-based HIPPI
network interface. The interface is very sensitive to the DMA performance characteristics of the host, and so requires careful tuning to
achieve reasonable performance. In addition, firmware is likely to change frequently, which necessitates a reasonably easy way to update
that firmware.
Available operands for eshconfig:
-b bytes
Adjust the burst size for read (by NIC of host memory) DMA.
-c bytes
Adjust the burst size for write (by NIC of host memory) DMA.
-d filename
Filename for file to download into NIC firmware. This must be a file in the standard Essential format, with :04 preceding every
line, and a tag line at the end indicating the characteristics of the firmware file.
-e Write data to EEPROM. Normally, setting tuning parameters will only persist until the system is rebooted. Setting this parameter
ensures that the changes will be written to EEPROM.
-i usecs
Interrupt delay in microseconds.
-m bytes
Minimum number of bytes to DMA in one direction (read or write) before allowing a DMA in the other direction. Tuning this prevents
one direction from dominating the flow of bytes, and artificially throttling the NIC.
-r bytes
Bytes before DMA starts for read (from host to NIC). This controls how soon the DMA is triggered; until this many bytes are
requested, the DMA will not begin.
-s Show statistics for the HIPPI NIC. Repeat the option to suppress non-zero statistics.
-t Show current tuning parameters on the host.
-u filename
Name of file to which the NIC firmware should be uploaded. Not currently supported.
-w bytes
Number of bytes required before write (from NIC to host) DMA is started. Until this many bytes are ready to be written, the DMA will
not start.
-x Reset the NIC. This is necessary for the HIPPI-FP support, as ifconfig(8) will no longer physically reset the NIC when the inter-
faces goes up and down.
Only the super-user may modify the configuration of a network interface.
DIAGNOSTICS
Messages indicating the specified interface does not exist or the user is not privileged and tried to alter an interface's configuration.

The eshconfig command first appeared in NetBSD 1.4.
