Solaris LDOM IP conflict

I have a Sun T4-1 running Solaris 11.4 with a static IP On this machine is a Solaris 10 LDOM with a static IP of The other day I had to stop the LDOM to do a memory reconfigure. When I rebooted it I got an error that the IP was already in use and so networking was disabled.

I discovered that if I ssh into, it comes up with the T4's primary domain. So I thought I'd jsut changed the Solaris 10 IP to But when I rebooted the LDOM, it complained that that IP was in conflict too! So somehow the primary domain has hijacked the Solaris 10's IP. So somehow my networking has gotten all bollixed up. The question is how to get the primary domain to give up

Here's some info from the primary domain but darned if I can figure out what needs to be changed:

You might considering flushing your ARP cache(s), or simply waiting until the ARP entries to timeout.

Current situation is :

Your T4 box has 3 IP addresses on three interface, from one which is VNIC net1 net0 vnic0
In one point in time, these addresses have been configured...

If you wish to remove the mentioned address found in this output :
vnic1             ip         ok           --         --
   vnic1/v4address static    ok           --

Execute the following on the hypervisor via SP or connected to any other address but 78 via ssh :
ipadm delete-addr vnic1/v4address

The system is complaining for duplicate address since you have one defined on VNIC in hypervisor and same inside LDOM.

Hope that helps

Thanks! The ipadm command worked! I now have networking again at on the LDOM. But now I have a new problem. When I start the LDOM console, it won't let me in. (But I can successfully ssh to the LDOM and also open a vncviewer to it).

Is this non-running service anything important?

Thanks. I didn't even know about that. That will be good to know for next time. In the end I went with the ipadm method.

I fixed the "no write access problem" by grepping for proceses named "telnet" and then killing them. Then I tried the "telnet localhost 5000" again and it worked fine. I next ran "svcs -xv" again and this time the "OCM process in maintenane mode" wasn't listed there anymore. So that seems to have fixed itself. Go figure.
