add 2nd SEA in VIO ?

[cla...@gmail.com]

Hi,
I tried to add a 2nd SEA to VIO but failed. Anyone has done this
before ?

The server is AIX P5-550,

$ ioslevel
2.1.0.10-FP-20.1

currently 1 SEA (ent7) is created, physical interface is ent4, and
Virtual I/O Ethernet Adapter is ent6, and is running OK.

$ lsmap -net -all
SVEA Physloc
------ --------------------------------------------
ent6 U9133.55A.XXXXXX-V2-C2-T1

SEA ent7
Backing device ent4
Status Available
...

now because some LPARs need to have one interface in IPv4 and another
in IPv6 , so I'm trying to use the physical interface ent5 to create
another SEA to serve the LPARs, so I added a 2nd virtual ethernet
adapter in VIO profile with "trunk adapter(access external network)"
option ("IEEE 802.1Q compatible adapter" option is not chosen because
we are not using VLAN tagging) , but when I tried to activate VIO, it
gave me error saying " HSCL 151A virtual ethernet trunk adapter with
the same MAC address already exists. " , and can't activate VIO. If I
don't choose the "trunk adapter(access external network)" option for
the 2nd Virtual eth adapter, I could boot VIO, but mkvdev would gave
error:

$ mkvdev -sea ent5 -vadapter ent8 -default ent8 -defaultid 1
Method error (/usr/lib/methods/cfgsea):
Failed to configure SEA with return code 64 and SEA-specific error
code 14:
Detailed info: Virtual adapter ent8 is not trunk: it needs to be
allowed to access external networks

Command did not complete.

Is there some limitation in VIO that only one SEA can be created to
access external network ? I searched for "dual SEA", but result are
mostly related to dual VIO for SEA failover.

Another option might be use dual VIO? with the 2nd VIO serve the IPv6
interface ? but I'm not sure if could assign the 2nd physical
interface to the 2nd VIO .

Thanks.

When you added your second virtual ethernet adapter, did you put give
it a unique vlan (pvid) id ? i.e if the first vethernet was say vlan
100, the second (new sea) would be something like 101, or 200 etc..

Based on the error message, have you checked that ent8 has been
configured as a trunk adapter? You can check this on the HMC.

if I check ent8 to be trunk adapter, can't active VIO, because ent6 is
already configured as trunk adapter in HMC.

to Mark Taylor , I tried with VLAN id, it's the same error, if I
check "trunk adapter", still can't boot VIO.

Thanks.

Hello

The second SEA must have à priority lower ( for example 2) and the first SEA
the higher priority of trunk ( 1)

Good luck

thanks everyone for reply.
It’s OK now, in the “ add the 2nd Virtual Ethernet adapter”
windows, need set the Port virtual Lan ID to “2”, because “1” is used
by the 1st virtual Ethernet adapter, that’s why I get the error.
