Virtual Switch in Solaris LDOM

Hi,

Our existing environment is having primary domain and 3 guest domains are running over it. See the attached image.

Now we want to add a new primary virtual switch and move LDOM3 to be connected with new primary switch.

So, I am not sure how to achieve this because. If I remove the existing virtual switch then all the LDOM can not be accessed. Can someone help in this matter.

Hi,

There is some excellent documentation on the Oracle site, I suspect that this article would be a good place to start.

I'm sure the picture is wrong.

You just need to add a vnet to a new ldom. You don't add vsw to ldoms.
Is your VSW an aggregation perhaps, created over an aggregated interface ?

If not, then you will not be redundant in case of NIC or switch failure.

Best regards

Hi,

Actually the figure is related to our UAT environment where we are not running any redundancy.

UAT LDOM are standalone and they are not as cluster.
So, I am wondering if I can just add a new virtual switch and then attach one of the LDOM to work with that switch.
If yes, how to achieve this?

Code:
ldm add-vnet vnet0 primary-vsw0 uatenv

You will now have net0 inside your ldom uatenv which is using primary-vsw.
Of course, you will still need to add disk devices.

In case of card/port failure or a switch failure, all the ldoms will lose network connectivity.

Hope that helps.
Best regards
Peasant.

Thanks for your reply.
Eventually I figured out the solution.

Here it is..
1. Add a new virtual switch
2. Plumb the interface
3. Assign IP and up the interface
4. Modify the existing vnet so that it can listen the new virtual switch
ldm set-vnet vswitch= primary-vsw1 vnet0 ldom03

vnet0 is interface for old switch.

Later after doing tests, I will again set vnet0 to old switch.

I hope it should work.

Thanks for your help.

I don't see a point in such setup not involving multiple network ports for bandwidth and failover.
Why would you have a server with multiple network ports and use one port for all your virtual machines ?

Aggregation is supported on vsw (vsw on top of aggr created interface).
With vlan tagging you could create multiple aggr interfaces with increased bandwidth and reliability hardware wise.

Also, a version of your operating system, ldom software and switch type would greatly help when initially asking help.
