Chapter 2 Setting Up XSCF 2-179
TABLE 2-31 lists terms used in domain mode 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.
TABLE 2-31 Domain Mode Configuration Terms
Term Description
Initial hardware
diagnostic level
Sets a POST 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 Oracle Solaris OS, to detect the Oracle Solaris OS hang-up. When
detected the Oracle Solaris OS hang-up, XSCF generates an Oracle 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 Oracle 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 Oracle 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 Oracle Solaris OS in single-user mode in an Oracle 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
mode
Operational mode for CPU hardware that Oracle Solaris OS uses. The CPU operational
mode includes the following two types:
• SPARC64 VII enhanced mode
Operates using the enhanced functions of the SPARC64 VII+ and SPARC64 VII processors.
This mode is set to domains that consist only of SPARC64 VII+ and SPARC64 VII processors
and when the CPU operational mode is determined automatically by Oracle 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.
