Checking the Client OBP for WAN Boot Support

To perform a hands-off WAN boot installation, the client OpenBoot PROM (OBP) must support WAN boot. The following procedure describes how to determine if the client OBP supports WAN boot.

To Check the Client OBP for WAN Boot Support

1. Become superuser on the client.

2. Bring the system to run level 0 (PROM monitor level).

   # init 0

   The ok prompt is displayed.

3. At the ok prompt, check the OBP configuration variables for WAN boot support.

   ok printenv network-boot-arguments

   • If the variable network-boot-arguments is displayed in the output of the previous command, the OBP supports WAN boot installations. You do not need to update the OBP before you perform your WAN boot installation.

   • If the message Unknown option: network-boot-arguments is displayed in the output of the previous command, the OBP does not support WAN boot installations. You must perform one of the following tasks. See your system documentation for information about how to update the OBP.

     • Update the client OBP. See your system documentation for information about how to update the OBP.

     • Perform the WAN boot installation from the Solaris 9 Software CD in a local CD-ROM drive. For instructions about how to boot the client from a local CD-ROM drive, see Installing With Local CD Media.

Example 41–1 Verifying OBP Support for WAN Boot on the Client

The following command shows how to check the client OBP for WAN boot support.

ok printenv network-boot-arguments
network-boot-arguments= 

In this example, the output network-boot-arguments= indicates that the client OBP supports WAN boot.
