Domain Mode Configuration Terms
TABLE 2-27
Term Description
Initial hardware Sets a POST diagnostic level.
diagnostic level
The following levels can be set:
• Maximum
• Standard
• None
Host watchdog Based on communication between XSCF and a domain, the host watchdog function checks
whether the domain is alive (heart beat or alive check). XSCF periodically monitors the
operational status of Solaris OS, to detect the Solaris OS hang-up. When detected the Solaris
OS hang-up, XSCF generates a Solaris OS panic on the relevant domain. To enable or disable
host watchdog, set the configuration file of scfd driver (scfd.conf) that installed in the
Solaris OS of the relevant domain. By enabling host watchdog (Alive Check function), XSCF
monitors the relevant domain.
Automatic boot The automatic boot function automatically boots the Solaris OS, such as to start a domain
and sets the auto-boot? OpenBoot PROM variable to either true or false.
If the automatic boot function is suppressed, it stops at an ok prompt, so that the user can
start the Solaris OS in single-user mode in a Solaris OS installation, for example.
Break signal "Break" means to forcibly interrupt data sending and restore the initial state. The signal used
for this purpose is called a break signal.
When a break signal is sent from a domain console, XSCF receives the signal and stops the
domain at an ok prompt.
Mode switch Switches on the operator panel. The mode switch has the following two modes:
• Locked: Normal operation mode
• Service: Maintenance mode.
CPU operational Operational mode for CPU hardware that Solaris OS uses. The CPU operational mode
mode includes the following two types:
• SPARC64 VII enhanced mode
Operates using the enhanced functions of the SPARC64 VII processor. This mode is set to
domains that consist only of SPARC64 VII processors and when the CPU operational mode
is determined automatically by Solaris OS.
• SPARC64 VI compatible mode
All the mounted CPUs operate with the functions equivalent to the SPARC64 VI processor.
This mode can be set for a domain of any CPU configuration.
Note – When the mode switch on the operator panel is set to Service, the automatic
boot and host watchdog functions are suppressed and the break signal is received,
regardless of the domain mode settings.
