celltype specifies the type of the cell. The valid celltype value for cells is:
base This is the default if celltype is not specified.
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 nor-
mally 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. 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 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 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 allo-
cated 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 parti-
tion, 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 shutdown 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 exam-
ple, the cell located in cabinet 0, slot 1 is identified in the local format as 0/1 or in the global
format as 1.
-B Specifies to reboot the partition now. The default is not to boot. If this option is specified
and the partition to be modified is not the local partition, then the command proceeds only
if the specified partition is not active. Also this option is useful only if the -a option or the
-d option or a clm_value has been specified.
