Hi gull04,

You're not wrong. On SPARC I use adb to modify the hostid. On both x86 and SPARC I insert lines at the end of /etc/rc2.d/S20sysetup so that they execute every time the machine boots.

Following below is a copy of the S20sysetup file from my SPARC system.

Again, I've not tested this code on Solaris 11 but it works great on Solaris 10.

All this stuff makes a good knowledge base for future readers and also means that you can help out on any hostid and lmgrd questions too. There doesn't seem to be too much knowledge about on this.
