use_on_next_boot specifies whether the cell will participate in a reboot. The valid
values for use_on_next_boot are:
y participate in reboot. This is the default. However if the slot is missing or
the cell does not exist or the cell is powered off then it defaults to
n
n
do not participate in reboot.
failure_usage field is used by system firmware when a partition is booted. If a CPU
selftest failure or a DIMM de-allocation 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
value for cells is:
ri reactivate with memory interleave. Specifies to integrate the cell as it would
normally be integrated. This is the default.
clm_value specifies the amount of the memory that will be configured as local (non-
interleaved) memory for the cell. The command issues 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, maximum interleaved memory(no clm) is assumed for
cells. 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 4GB memory, then
the percentage will be rounded to 25%, 50%, 75% or 100%. The specified percen-
tage 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
8GB memory and the user specifies 4GB CLM. When the partition boots 4GB of
that cell’s memory will be used as CLM. Later the user shuts down the partition,
adds another 8GB memory to that cell. When the partition is booted again, the
cell now has 16GB of memory, so 8GB (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 0.5GB. For example:
2.5GB will not be rounded up. However 2.3GB will be rounded up to 2.5GB. For
example, a cell in a partition has 8GB memory and the user specifies 50% CLM.
When the partition boots 4GB of that cell’s memory will be used as CLM. Later
the user shuts down the partition, adds another 8GB memory to that cell. When
the partition is booted again, the cell now has 16GB of memory, but the CLM is
still 4GB.
-m cell:[celltype]:[use_on_next_boot]
:[failure_usage][:clm_value]
Modify attributes of cell(s) already assigned to the target partition. Please refer to the
explanation of the
-a option for details of the different fields in this option argument.
Note:
• The use_on_next_boot field of the last cell containing core IO cannot be modified to
n.
• If modifying the CLM value of a cell in any partition other than the local partition,
it is preferable to use the -u option.
-d cell Delete the specified cell(s) from the partition. If the cell which is being deleted is an
active cell then after the execution of the parmodify command the user must shut-
down the partition using the shutdown -R command for the configuration change
to take effect. If the -B option is also specified then the partition will boot up to the
command prompt. If the -B option is not specified then the partition will have to be
booted manually from the service processor. Deletion of inactive cells does not require
a shutdown of the partition.
A cell can be specified either in the local (cabinet#/slot#) or global (cell#) format. For
example, the cell located in cabinet 0, slot 1 is identified in the local format as 0/1 or in
the global format as 1.
