How to find pair VIOS?

UNIX AIX
1

Hi,

I have the scenario, that there 3 VIOS in a Frame in this 2 are in dual VIOS

My question is how to find which VIOS are in dual?

Also, any vios command to identify the pair member (hostname) of a dual VIOS

Regards,
Siva

One way would be to look from the perspective of a client.

On the HMC look at a client definition of it's virtual interfaces. This will show which VIOS (pair) it connects to.

If I had an HMC I would show the command, but I do not. It will be very similar to what I used before from the IVM perspective (there is only one IVM).

The command: lssyscfg -r prof -F name,os_type,virtual_eth_adapters --header (probably still needs a -m managedSystem when used from an HMC will list the virtual ethernet adapters. From this you might be able to discover which two are the VIOS pair (common virtual_eth_adapters to support SEA failover).

Hope this helps you search!

Hi Michael,

Thanks for ur info. From the below output how to find out which 2 pairs.

Normal,vioserver,"64/0/3567//0/0/ETHERNET0,65/0/3568//0/0/ETHERNET0,12/0/266//1/0/ETHERNET0,13/0/265//2/0/ETHERNET0,14/0/567//1/0/ETHERNET0,62/0/3266//0/0/ETHERNET0,15/0/568//2/0/ETHERNET0,63/0/3265//0/0/ETHERNET0"

Well, as my command was originally from an IVM the name variable is not helping much here as your profile name is "Normal" in all situations.

It looks like you have two pairs of two - since there are 4 lines, and the profile name is identical (i.e., cannot have the same profile name twice in a single partition).

Looking at the first virtual Ethernet entry in each of the profiles the logical conclusion is the the first two are one pair, and the second two are the second pair.

What I also notice looking at the second pair - is that they are less consistent than the first pair.

An additional field/attribute(s) to print would be, from memory lpar_id, lpar_name .
These would help in the specification of the partition names and identify the pairs parition names and/or id number.
