To start the host console, you must specify the PDomain number to which you want to connect. On a SPARC M8-8 or SPARC M7-8 server with two PDomains, the PDomain numbers are either 0 or 1. On a SPARC M8-8 or SPARC M7-8 server with one PDomain, the PDomain number is always 0. The SPARC M7-16 server has one host console for each of the four possible PDomains.
This task uses PDomain_0, HOST0, and DCU_0 as examples. This task also assumes that the host is already running. You must have the console role (c) to complete this task.
Check the system health property. If it indicates that the system requires service, check the health details. You might need to address some or all of the faults. The following output has been edited for clarity. The output shows that there are two open problems. As indicated, run the show /System/Open_Problems command to view details about the faults.
-> show /System

This output has been edited for clarity. If the power_state property is Off, you can start the host console, but the PDomain prompt is not displayed. If the power_state property is Off, the host is not running. If the status value is OpenBoot Primary Boot Loader or OpenBoot Running, the host is running, but it is at the ok prompt. Finally, if the value is Solaris running, the host is running, and it is at the Oracle Solaris prompt.

If the host has no DCUs assigned to it, you cannot start the host, nor can you start the host console. This message is displayed if you try to start the host console:
Set dcus_assigned for /HOST0 before starting console.
If no DCUs are assigned, see Assign a DCU to a Host.

-f|force – Enables you to take control of the console from any current user and to force that user into view mode. You must have the console role (c) to use this option. If you use this option, other users will receive warnings that their connections have been forced into read-only mode. Each time a console session that used the -f|force option exits, read-write status is restored to the next user in line with the first user’s read-write status being restored last.
-script – Bypasses the prompt for a yes or no confirmation.
