Fujitsu M10 Installation Manual page 249

When installing a chassis that has been removed into another system, you need to
reinstall the key during the initial setup of the XSCF after the installation of the
chassis.
The physical partition number must match the BB-ID value of one of the SPARC
■
M10-4S units in the system.
Therefore, if there is a physical partition with the same number as that of the
BB-ID of the SPARC M10-4S to be removed, stop that physical partition before
removing the unit.
If the removed SPARC M10-4S unit will not be used in the system, it will not be
possible to use the corresponding physical partition. So reconfigure the physical
partition with a different physical partition number.
Notes on use of dynamic reconfiguration (DR) for the physical
partition
Note - When using the dynamic reconfiguration function for the physical partition (PPAR
DR), check the contents of "2.5 Dynamic Reconfiguration Conditions and Settings" in the
Fujitsu M10/SPARC M10 Systems Domain Configuration Guide beforehand.
The command with the -c unassign option specified cannot release a system board
■
(PSB) from a physical partition where the PPAR DR function is disabled, while the
physical partition is operating. Execute the setpparmode command beforehand to
set the PPAR DR setting to "on".
For details, see "A.1 Updating a System that Does Not Support Physical Partition
Dynamic Reconfiguration to One that Does Support It" in the Fujitsu M10/SPARC
M10 Systems Domain Configuration Guide.
To release a system board (PSB) from the physical partition, execute the
■
deleteboard command with the -c unassign option specified. After being released
from the physical partition by the command with the -c unassign option specified,
the system board (PSB) enters the system board pool.
When the system board (PSB) is targeted for release from the physical partition,
■
the free resources in the physical partition are used to move the logical domains
that use the resources of the system board (PSB).
According to the status of these free resources, you can specify the method of
securing the resources used to move the logical domains by specifying the -m
option of the deleteboard command.
The following shows the functions when the -m option of the deleteboard
command is specified.
- When -m unbind=none is specified
Obtains resources for the move from available resources. When the command
cannot secure the resources, it causes the release to fail.
- When -m unbind=resource is specified
Obtains resources for the move from available resources. If even those resources
are insufficient, it secures resources from each logical domain.
