spconfig command to save the logical domain configuration in XSCF.
In either of the following cases, the logical domain configuration of a physical
partition returns to the factory-default state at the next start time. Furthermore, the
OpenBoot PROM environment variables of the control domain are initialized for any
guest domains included in the logical domain configuration.
The firmware XCP 2044 or later (for the SPARC M10-4) or the firmware XCP 2050
■
or later (for the SPARC M10-4S) and the setpciboxdio command are used to
change the enable/disable setting for the direct I/O function of the PCI expansion
unit.
The firmware XCP 2044 or later (for the SPARC M10-4) or the firmware XCP 2050
■
or later (for the SPARC M10-4S) is used to perform the following: installation/
removal/replacement of the PCI expansion unit for the PCI slot of the SPARC M10
chassis for which the direct I/O function of the PCI expansion unit has been
enabled with the setpciboxdio command.
Save the logical domain configuration information from Oracle Solaris to XML in
advance.
Execute the ldm list-constraints -x command to save it to XML, and execute the ldm
init-system -i command to restore it from XML. Also, keep a note of the setting
information for the OpenBoot PROM environment variables of the control domain in
advance to set them again. To display the information, execute the printenv
command at the ok prompt. For detailed procedures, see "1.7.3 How to save/restore
the logical domain configuration information and the OpenBoot PROM environment
variable" in the PCI Expansion Unit for Fujitsu M10/SPARC M10 Systems Service Manual.
The following table outlines the required work for saving/restoring each type of
information before executing the setpciboxdio command to change the enable/disable
setting for the direct I/O function of the PCI expansion unit.

When performing the installation/removal/replacement of the PCI expansion unit for
the PCI slot of the SPARC M10 chassis for which the direct I/O function of the PCI
expansion unit has been enabled by executing the setpciboxdio command, the
following table indicates whether specific information must be saved/restored in each
of the different cases.
Note - When maintaining the PCI expansion unit by using the PHP function, since the direct
I/O function is disabled, the information does not need to be saved/restored.
