I know you've figured it out now, but thought i'd post my notes anyway incase they are useful
lscfg shows the hardware addresses of all hardware
lscfg -pvl ent1 will give more detail for an individual device (e.g. ent1)
on my box:
# lscfg -pvl ent1
ent1 U788C.001.AAC1535-P1-T2 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
2-Port 10/100/1000 Base-TX PCI-X Adapter:
Network Address.............001125C5E831
ROM Level.\(alterable\).......DV0210
Hardware Location Code......U788C.001.AAC1535-P1-T2
PLATFORM SPECIFIC
Name: ethernet
Node: ethernet@1,1
Device Type: network
Physical Location: U788C.001.AAC1535-P1-T2
Is an 'Internal Port'
whereas ent2
# lscfg -pvl ent2
ent2 U788C.001.AAC1535-P1-C13-C1-T1 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
2-Port 10/100/1000 Base-TX PCI-X Adapter:
Part Number.................03N5298
FRU Number..................03N5298
EC Level....................H13845$
Brand.......................H0
Manufacture ID..............YL1021
Network Address.............001A64A8D516
ROM Level.\(alterable\).......DV0210
Hardware Location Code......U788C.001.AAC1535-P1-C13-C1-T1
PLATFORM SPECIFIC
Name: ethernet
Node: ethernet@1
Device Type: network
Physical Location: U788C.001.AAC1535-P1-C13-C1-T1
is on an PCI I/O card
For a physical address e.g.
U788C.001.AAC1535-P1-C13-C1-T1
U788C.001.AAC1535 - this part identifies the 'system unit/draw'. If your system is made up of several draws then look on the front and match the ID to this section of the address.
Now go round the back of the server
P1 This is the PCI bus number. You may only have one.
C13 - Card Slot C13 - They should be numbered on the back of the server
C1-T1 - this is port 1 of 2 that are on the card.
Your internal ports won't have the Card Slot numbers, just the T number, representing the port. This should be marked on the back of your server
e.g. U788C.001.AAC1535-P1-T2 means unit U788C.001.AAC1535 PCI bus P1 port T2 and I would expect to see T2 printed on the back of the server.
Hope that makes sense, haven't had time to proof read this!
