Holger,
Exactly, you don't assign IP's to ent1 or ent0. A 'virtual' ent2 will be
created after your etherchannel configuration, at that time ent0 and ent1
will not show up using 'lsdev -Cc adapter'. You then go into TCPIP minimum
configuration and select ent2 as the adapter you want to configure an IP
address for. Here is what mine looks like:
root@lpar1] /-> lsdev -Cc adapter
sa0 Available 01-S1 Standard I/O Serial Port
sa1 Available 01-S2 Standard I/O Serial Port
fda0 Available 01-D1 Standard I/O Diskette Adapter
ssa0 Available 2V-08 IBM SSA 160 SerialRAID Adapter (14109100)
fcs0 Available 2b-08 FC Adapter
scsi0 Available 2s-08 Wide/Ultra-3 SCSI I/O Controller
ent0 Available 2v-08 Gigabit Ethernet-SX PCI Adapter (14100401)
scsi1 Available 3A-08 Wide/Fast-20 SCSI I/O Controller
fcs1 Available 3V-08 FC Adapter
ent1 Available 3p-08 Gigabit Ethernet-SX PCI Adapter (14100401)
scsi2 Available 3s-08 Wide/Ultra-3 SCSI I/O Controller
sa2 Available LPAR Virtual Serial Adapter
ent2 Available Etherchannel
As for 'Alternate etherchannel', I kept all that blank except for the
'mode', 'number of retries' and 'Retry timeout'.
The Alternate address will fill itself in after your finished with the
configuration.

Enable ALTERNATE ETHERCHANNEL address no

Thanks for the response.
I dont understand this sentence:
Without any configuration to en0 or en1, set up en2 as you normally would a
regular network adress.
Do you speak about IP or MAC-Adress? en0 and en1 wont have any ip, right?
What did you configure for
Enable ALTERNATE ETHERCHANNEL address no
+
ALTERNATE ETHERCHANNEL address []
+
I simply cant get any information... there is not even help in smitty.

I just finished up with a couple adapters running backup mode. The RedBook
(5L differences) is a little grey on this instruction.
For both adapters on the system:
Remove all en0 and en1 interfaces
ifconfig en0 down
ifconfig en0 detach
rmdev -dl en0
rmdev -dl ent0
rmdev -dl et0
cfgmgr -v
After cfgmgr check to see if the adapters are 'available' again, 'lsdev -Cc
adapter'.
I used 'smitty etherchannel' for the rest of the configuration. Choose ent0
and ent1 to make up your etherchannel (the redbook describes the fields on
page 364). This will show up as en2. Without any configuration to en0 or
en1, set up en2 as you normally would a regular network adress. 'smitty
tcpip' minimum configuration. I tested this yesterday and the failover works
perfectly. One adapter will will sit waiting for the other to fail and take
over after the times you set in the etherchannel setup. Mine came back after
about a minute.
HTH,
Darryl

Hello,
I would like to use the 5L features
- dead gateway detection
- virtual ip address
- network interface backup mode
to keep the impact on my systems from defects on nics, switches, routers as
small as possible. All system have 2 nics.
Did anybody write a concept about this he likes to share?
Where can I find more precise information about these features?
All I have is
- Redbook 5L differences guide
-
