OK, I guess using this ...
set md:mirrored_root_flag=1 for Solaris Volume Manager (SVM) is not supported and could cause problems. I guess it's back to my first idea ... With 2 disks, setup three SDR's (State Database Replicas) Drive 0 = 1 SDR -> If this drive fails auto-magically boot DRIVE 1 Drive 1 = 2 SDR's -> If this drive fails Sysadmin intervention required Well that's OK, at least 50% of the time the system won't KACK. Thanks for the help. I am pleasantly surprised with the level of Sun Staff involvement to help things along. Much appreciated Richard and other Sun Staff!!
