An Oracle Solaris OS server is a server that provides operating system (OS) services to support diskless client systems. You can add support for an OS server or convert a stand-alone system to an OS server by using the smosservice command.
For each platform group and Oracle Solaris release that you want to support, you must add the particular OS service to the OS server. For example, if you want to support SPARC sun-4u systems running Oracle Solaris , you must add sun-4u/Oracle Solaris 10 OS services to the OS server. For each diskless client that you support, you must add the OS service for that client to the OS server. For example, you would need to add OS services to support SPARC sun-4m systems or x86 based systems that run Oracle Solaris 10 or the Solaris 9 release, because they are different platform groups.
You must have access to the appropriate Oracle Solaris software CD, DVD, or disk image to add OS services.
