OS Server and Diskless Client Support Information

---

Caution –

Attempts to add diskless client support using an OS client-server configuration where one system implements the new boot architecture, but the other system does not, can result in major incompatibilities. New boot (GRUB) was implemented on the x86 platform, starting with the Solaris 10 1/06 release and on the SPARC platform, starting with the Solaris 10 10/8 release. Note that adding diskless support on systems that are running a Solaris release that is more recent than that which is running on the OS server is also an unsupported configuration. To avoid potential problems, it is recommended that you install the latest Solaris release before adding diskless client support.

The Solaris releases and architecture types that are supported by the smosservice and smdiskless commands include the following:

• SPARC based servers: Supported in the Solaris 8, Solaris 9, and Solaris 10 releases

• SPARC based clients: Supported in the Solaris 8, Solaris 9, and Solaris 10 releases

• x86 based servers: Supported in the Solaris 9, and Solaris 10 releases

• x86 based clients: Supported in the Solaris 9, and Solaris 10 releases

The following table shows the x86 OS client-server configurations that are supported by the smosservice and smdiskless commands. This information applies to the Solaris 9 and the Oracle Solaris 10 FCS (3/05) release.

If you are running at least the Solaris 10 1/06 release, it is recommended that you install or upgrade to the same release before adding diskless client support.

The following table shows the SPARC OS client-server configurations that are supported by the smosservice and smdiskless commands. This information applies to the Solaris 8 and Solaris 9 releases, and the Oracle Solaris OS, up through the 10 5/08 OS.

If you are running at least the Solaris 10 10/08 release, it is recommended that you install or upgrade to the same release before adding diskless client support.
