TABLE 3-8 Service-Related ALOM CMT Commands
ALOM CMT Command Description
help [command] Displays a list of all ALOM CMT commands with syntax and descriptions.
Specifying a command name as an option displays help for that command.
break [-y][-c][-D] Takes the host server from the OS to either kmdb or OpenBoot PROM
(equivalent to a Stop-A), depending on the mode Solaris software was
booted.
• -y skips the confirmation question
• -c executes a console command after the break command completes
• -D forces a core dump of the Solaris OS
clearfault UUID Manually clears host-detected faults. The UUID is the unique fault ID of
the fault to be cleared.
console [-f] Connects you to the host system. The -f option forces the console to have
read and write capabilities.
consolehistory [-b lines|-e
lines|-v] [-g lines]
[boot|run]
Displays the contents of the system’s console buffer. The following options
enable you to specify how the output is displayed:
• -g lines specifies the number of lines to display before pausing.
• -e lines displays n lines from the end of the buffer.
• -b lines displays n lines from beginning of buffer.
• -v displays entire buffer.
• boot|run specifies the log to display (run is the default log).
bootmode
[normal|reset_nvram|
bootscript=string]
Enables control of the firmware during system initialization with the
following options:
• normal is the default boot mode.
• reset_nvram resets OpenBoot PROM parameters to their default
values.
• bootscript=string enables the passing of a string to the boot
command.
powercycle [-f] Performs a poweroff followed by poweron. The -f option forces an
immediate poweroff, otherwise the command attempts a graceful
shutdown.
poweroff [-y][-f] Powers off the host server. The -y option enables you to skip the
confirmation question. The -f option forces an immediate shutdown.
poweron [-c] Powers on the host server. Using the -c option executes a console
command after completion of the poweron command.
