Working With Diskless Client Commands

By writing your own shell scripts and using the commands shown in the following table, you can easily set up and manage your diskless client environment.

Table 7-3 Diskless Client Commands

You can obtain help on these commands in two ways:

• Use the -h option when you type the command, subcommand, and required options. For example, to display the usage statement for smdiskless add type the following:

  % /usr/sadm/bin/smdiskless add -p my-password -u my-user-name -- -h

  
  

• View the smdiskless(1M) or smosservice(1M) man pages.

Required RBAC Rights for Diskless Client Management

You can use the smosservice and smdiskless commands as superuser. If you are using Role-Based Access Control (RBAC), you can use of either a subset or all of the diskless client commands, according to the RBAC rights to which they are assigned. The following table lists the RBAC rights that are required to use the diskless client commands.

Adding OS Services

A 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 standalone system to an OS server with the smosservice command.

For each platform group and 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 Sun4m systems running the Solaris 8 release, you must add Sun4m/Solaris 8 OS services to the OS server. You would also still need to add OS services to support SPARC Sun4c systems or x86 based systems that runs the Solaris 8 release, because they are different platform groups.

You must have access to the appropriate Solaris CD or disk image to add OS services.

Adding OS Services When the OS Server Has Been Patched

When adding OS services to an OS server, you might see error messages saying that you have inconsistent versions of the OS running on the server and the OS that you are trying to add. This message occurs when the installed version of the OS has packages that were previously patched and the OS services being added do not have those packages patched (because the patches have been integrated into the packages).

For example, you may have a server that is running the Solaris 7 release. You may also have additional OS services loaded on this server, including the Solaris 2.6 SPARC sun4m OS services that have been patched. If you try to add the Solaris 2.6 SPARC sun4c OS services from a CD-ROM to this server, you could get the following error message:

Error: inconsistent revision, installed package appears to have been 
patched resulting in it being different than the package on your media. 
You will need to backout all patches that patch this package before 
retrying the add OS service option.

Disk Space Requirements for OS Servers

Before you set up your diskless client environment, make sure you have the required disk space available for each diskless client directory.

In previous Solaris releases, you were prompted about diskless client support during the installation process. In the Solaris 9 release, you must manually allocate an /export file system either during installation or create it after installation. See the following table for specific disk space requirements.
