2-174 SPARC Enterprise Mx000 Servers XSCF User’s Guide December 2010
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.
