Solaris LDOM IP conflict
I have a Sun T4-1 running Solaris 11.4 with a static IP 192.168.0.183. On this machine is a Solaris 10 LDOM with a static IP of 192.168.0.78. 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 192.168.0.78 was already in use and so networking was disabled.

I discovered that if I ssh into 192.168.0.78, it comes up with the T4's primary domain. So I thought I'd jsut changed the Solaris 10 IP to 192.168.0.79. 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 192.168.0.78?

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

Code:
