nPartition Administrator's Guide

failure_usage field is used by system firmware when
a partition is booted. If a CPU selftest failure or a DIMM
deallocation occurs during the power-on self-test process,
then this flag is used by the system firmware to determine
whether or not and how the cell should be integrated into
the partition at boot time. The valid failure_usage
values for a cell are:
ri Reactivate with memory interleave. Specifies to
integrate the cell as it would normally be integrated.
This is the default for base cells.
float this is the default value for floating cells. If the
user specifies ri for a floating cell, the command
displays an error and exits.
deconf deconfigure.
ni no interleave.
clm_value specifies the amount of the memory that will
be configured as local (noninterleaved) memory for the
cell. The command will issue a warning if the specified
clm_value exceeds the total memory of the cell.
NOTE: On PA-RISC platforms, the amount of memory
allocated for CLM may not match the amount of CLM
requested due to some memory being reserved exclusively
by the operating system.
If no clm_value is specified, policy rules (specified
through -Z option) will be applied to the cell to determine
the amount of Interleaved memory and Local Memory for
the cell. The command will issue a warning if 100% CLM
is specified for all the cells in the partition. The clm_value
can be expressed in two forms:
As a percentage (ratio)
The percent number can be any number in the range 0 -
100 with a suffix of %. This number will be rounded up to
12.5%, 25%, 37.5%, 50%, 62.5%, 75%, 87% or 100%. If the
cell contains less than 4 GB memory, then the percentage
will be rounded to 25%, 50%, 75% or 100%. The specified
percentage is applied each time the partition boots, thus
resulting in a different value if the working memory in the
cell is different. For example, a cell in a partition has 8 GB
memory and the user specifies 50% CLM. When the
partition boots, 4 GB of that cell’s memory will be used as
CLM. Later the user shuts down the partition, adds another
8 GB memory to that cell. When the partition is booted
again, the cell now has 16 GB of memory, so 8 GB (50%) is
allocated as CLM.
As an absolute number (default)
This can also be optionally suffixed by GB. The clm_value
is interpreted as an absolute number of gigabytes of
memory. Numbers other than integers and halves are
rounded up to the nearest 0.5 GB. For example, 2.5 GB will
not be rounded up. However 2.3 GB will be rounded up
to 2.5 GB. For example, a cell in a partition has 8 GB
memory and the user specifies 4 GB CLM. When the
partition boots 4 GB of that cell’s memory will be used as
CLM. Later the user shuts down the partition, adds another
