When using the Oracle Solaris Automated Installer (introduced with Oracle Solaris 11) to deploy software on a server, the server's Host-to-ILOM interconnect feature (required for many Oracle Hardware Management Pack features) might be left in a disabled state after the Automated Installer performs a reboot during installation.
To determine if your server was set up by the Automated Installer, enter the following command:
# netadm list | grep ncp
ncp Automatic online <-- Automated Installer was used ncp DefaultFixed disabled
Workaround
If this happens, reboot the server a second time after the installation has completed.
