VIO SEA Error

Posted on 2014-02-06

I am attempting to create a Shared Ethernet Adapter on my VIO server (which will service my iSeries partitions).

When I attempt to create the SEA, I get the following error

Failed to configure SEA with return code 22 and SEA specific error code 9:
Opening real adapter ent18 failed with error 22.

We have successfully created a SEA on our VLAN2, but when we attempt to create this SEA for our VLAN 1...we are having issues.

Anyone have any ideas?

Thanks!

Could it be that there is already a protocol device en18 configured over ent18?
Or is ent18 already in use for another SEA?

If so this keeps the adapter from being opened by cfgsea (mkvdev).

Check (as padmin) with

lsdev | grep en18

If you see "Available" then check the settings:

lsdev -attr -dev en18

You will see the IP config, if any.

Decide whether you must keep this address or not. Depending on this decision either choose a different adapter or remove the device with

rmdev -dev en18

Then run "cfgdev" to reconfigure the en18 device as "Defined" and proceed with configuring the SEA.

Note: You can check which adapters are eligible for SEA with

lsdev -type ent4sea

and you can see your SEAs with

lsdev -type sea

We don't have any interfaces configured for our ent18 which is a Etherchannel:

lsdev -type ent4sea

 ent13           Available   4-Port Gigabit Ethernet PCI-Express Adapter (e414571614102004)

We are attempting to connect the SEA to ent18

Well,

the only instance where I saw such behaviour was under out-of-memory conditions, but this was error 12, not 22.

Anyway, how much memory does the VIOS partition have? IBM recommend assigning 2 GB per processor core.

SEA RC 9 means something like "Device not ready". Are you sure that this Etherchannel is in a good state? Are the underlying adapters "Available"?

I'd recommend removing the Etherchannel (lnagg) device and its adapters completely.

Then re-detect the physical adapters with "cfgdev". Are these still "Available"?

If so, recreate the lnagg and retry cfgsea.

If the physical adapters don't show up as "Available" or don't show up at all check the VIOS LPAR config on the HMC.

We tried all of the recommendations you suggested (multiple times). We are running 12 GB of memory on each of our VIO servers, so I think we should have plenty of memory.

Are physical adapters appear to be in OK shape....at least we don't see any issues with them and they are all showing link lights and appear to be in a good state. (everything shows available

>> We tried all ... <<

Did you remove/recreate the LNAGG including its physical adapters?

Is the virtual adapter (l-lan) to be bridged by the SEA allowed "Use this adapter for Ethernet Bridging"?

If both of the above is true all that I can still recommend is checking the error log ("errlog" as padmin). If there's also nothing I fear I can't help any further.

Perhaps you should open a ticket with IBM.

We deleted the ENT18 (LNAGG) completely and recreated the entire aggregate link (multiple times....

We had to delete all of the adapters that made up the aggregate and let them re-populate. Then, we were able to re-create the aggregate and then ultimately the SEA

Fine, that's exactly what I suggested. Glad to see it worked!

Thx for the points!
