What do you mean by configuring zones using SMC ? AFAIK, SMC can't let you do that... but perhaps am I too much CLI addict and haven't checked for all new features... What you should do first is to check if your /etc/security/tsol/tnzonecfg is well setted and if your zones are well declared regarding their label. You should find lines such as : <name_of_zone>:<hex_label>:1:: One for each of your zones. If you do not have such lines, add them. You can know the hex labels with the command atohexlabel (i.e. atohexlabel "CNF NEED TO KNOW") Then, check for your zones. Have they booted ? (zoneadm list -cvi will tell you that) Haven't you forget to complete their installation at first boot ? (zlogin -C <your_zone_name>, then <return>. If your zones have not been configured yet, you will have the CLI config menu. Otherwise, you will have your zone login prompt...) Let us know how you progress, HTH, Bruno.
