Hello, I'm not sure I'll be able to help you. I'm using ldoms on T5 running Solaris 11.2. According to blog [1], the /var/adm/messages in primary domain (ldom0) should give you some hint on what is going on.
I hope it will help you to get unstuck. regards sasha [1] https://blogs.oracle.com/vmserver/entry/device_validation_with_ldoms_2 On Wed, Apr 19, 2017 at 05:00:07PM +0100, Andrew Grillet wrote: > Hi, > > how _exactly_ does a guest domain connect to a virtual disk? > > I am asking this because I installed 6.1 onto my system which had > been running 6.0.
