VIOS SEA Creation

UNIX AIX

Hi Guys,

I'm getting the below error while trying to create a SEA adapter in VIOS

$ mkvdev -sea ent0 -vadapter ent2 -default ent2 -defaultid 1

Not sure what this means.. Can someone throw some light in this :frowning:

Depending on which AIX version you are using the following link may or may not apply to your problem:

IBM IZ03360: HDISK CANNOT BE CONFIGURED; FAILS WITH 0514-040 APPLIES TO AIX 5300-07 - United States

I hope this helps.

Its fixed bakunin. Actually its not allowing us to configure the same interface used for SEA to configure IP for the VIO server.. Created one more virtual Ethernet and used it for assigning IP.

Thanks :slight_smile:

IBM use to recommend creating another virtual network adapter, which it sounds like you did, for the IP address. When we setup our first Power 5 box, we put the network configuration on the SEA. At that time, IBM told us that every packet was getting inspected by the SEA and, therefore, slowing down all the network traffic.

Last time I talked to an IBM VIO server engineer, they told me that they now recommend that the network configuration be placed back on the SEA instead of an extra network adapter. We saw performance gains when we moved off it, so we are in no rush to move it back to the SEA.

I'm not saying you should move it over to your SEA or leave it where it is, I'm just passing on information I got from IBM.

I think you may need to set ctl_chan,

for example: mkvdev -sea ent0 -vadapter ent2 -default ent2 -defaultid XX -attr ctl_chan=ent3 ha_mode=auto
