Thanks for your answer Bakunin, but the problem was bigger than what you and I thought.
We have an Etherchannel setup on our P5-590's, and here's the answer from IBM support:
Unforunately, Etherchannel (and other multiple adapter protocols,
like VIPA, Virtual IP Addressing) is not supported with NIM.
NIM requires, when performing a network boot for a client, that
-all- network traffic occur between only -two- adapters: The NIM
primary network adapter and the client's configured network adapter
(for boot purposes).
Etherchannel attempts to "load balance" network traffic by distributing
the network traffic for the system among the multiple adapters it has
in its configuration. This means that a BOOTP request can come in
one of the Etherchannel network adapters, but the response to the
client goes out another adapter, and is ignored by the client,
because the response packet was send by a different adapter than
the adapter that received it.
This behaviour prevents NIM from performing network boots of clients.
The only recourse is to either remove the Etherchannel configuration
from the NIM master system, or separate a -dedicated- network
adapter for use by NIM -only-, such that only NIM traffic can go out
and be received by this adapter.
There is also an unsupported method of getting Etherchannel and
NIM to cooperate. You can set the Etherchannel device to
"netif_backup", with one adapter acting as the 'primary' network
adapter for the system, and the other second adapter acting as a
"Backup Adapter", so that all network traffic goes in and out of
the 'primary' adapter, and the 'backup' adapter is only on standby,
to take over if the 'primary' adapter fails. This method is
unsupported, because the Etherchannel failover to the backup
adapter could happen in the middle of a NIM network boot of a
client, and will cause the network boot to fail.

Friend's,
I was playing around with NIM in my environment & had a quick question in mind which I didn't/couldn't find answer to, which is -- how to find the name of the NIM server sitting on the NIM client?
All leads to the answer would be much appreciated, many thanks!

NAME
bt-adapter - a bluetooth adapter manager
SYNOPSIS
bt-adapter [OPTION...]
Help Options:
-h, --help
Application Options:
-l, --list
-a, --adapter=<name|mac>
-i, --info
-d, --discover
--set <property> <value>
DESCRIPTION
This utility is used to manage Bluetooth adapters. You can list all available adapters, show information about adapter, change adapter
properties or discover remote devices.
OPTIONS
-h, --help
Show help
-l, --list
List all available adapters
-a, --adapter <name|mac>
Specify adapter to use by his Name or MAC address
(if this option does not defined - default adapter used)
-i, --info
Show information about adapter (returns all properties)
-d, --discover
Discover remote devices (with remote device name resolving)
--set <property> <value>
Change adapter properties (see ADAPTER PROPERTIES section for list
of available properties)
ADAPTER PROPERTIES
string Address [ro]
The Bluetooth adapter address (MAC).
string Name [rw]
The Bluetooth adapter friendly name.
uint32 Class [ro]
The Bluetooth class of device.
boolean Powered [rw]
Switch an adapter on or off. This will also set the
appropiate connectable state.
boolean Discoverable [rw]
Switch an adapter to discoverable or non-discoverable
to either make it visible or hide it.
If the DiscoverableTimeout is set to a non-zero
value then the system will set this value back to
false after the timer expired.
In case the adapter is switched off, setting this
value will fail.
boolean Pairable [rw]
Switch an adapter to pairable or non-pairable.
Note that this property only affects incoming pairing
requests.
uint32 PaireableTimeout [rw]
The pairable timeout in seconds. A value of zero
means that the timeout is disabled and it will stay in
pareable mode forever.
uint32 DiscoverableTimeout [rw]
The discoverable timeout in seconds. A value of zero
means that the timeout is disabled and it will stay in
discoverable/limited mode forever.
The default value for the discoverable timeout should
be 180 seconds (3 minutes).
boolean Discovering [ro]
Indicates that a device discovery procedure is active.
list UUIDs [ro]
List of 128-bit UUIDs that represents the available local
services.
