■
The poweroff(8) and reset(8) commands may not be executed normally if all XSCF
have not been restarted due to an error in a XSCF in the SPARC M10-4S that is
composed of more than two cabinets.
To disconnect the power of a physical partition (PPAR), login to the control
domain of the PPAR and execute the shutdown(1M) command on Oracle Solaris.
Then, disconnect the power of the PPAR using the poweroff -f command on the
XSCF firmware. The reset(8) command cannot be used in this state.
The -c wait option, which is used to set the air-conditioning wait time for the
■
setpowerupdelay(8) command, is not supported at present.
Ask your sales representatives regarding the support information of the dynamic
■
reconfiguration of the system board (PSB).
The command options related to the dynamic reconfiguration are as follows.
-c configure of the addboard(8) command
■
-c disconnect of the deleteboard(8) command (when the PPAR is powered on)
■
-c unassign of the deleteboard(8) command (when the PPAR is powered on)
■
The -p option of the diagxbu(8) command is not supported at present.
■
The setpciboxdio(8) and showpciboxdio(8) commands are not supported at present.

If you power on all physical partitions (PPAR) in a system that has more than one
PPARs with the poweron(8) command, the startup time taken when specifying
power-on of PPAR is longer than the time taken for batch power-on by specifying
-a.

As for the ioreconfigure that can be specified by -m function of the setpparmode
(8) command, leave it as the default, false, and disable the I/O bus reconfiguration
function. If you enable the I/O bus reconfiguration function by specifying true to
the ioreconfigure, it may be necessary to reinstall Oracle Solaris.
