HP-UX Virtual Partitions Administrator Guide (includes A.05.09) (5900-2188, March 2012)

where
nPar_num is the nPartition number
cell is the cell to be modified. this can be either the global format (cell_number) or
hardware format (cabinet/slot)
type is the cell type. base is the only valid value and is the default.
use is the use-on-next-boot value. this is either a y or n. The default is y. Use y if the cell
is to be an active member of the nPartition or n if the cell is to be an inactive member
fail is the cell failure usage. the only valid value is ri (reactivate with interleave) and is
the default
clm is the amount of memory that will be configured as cell local memory for the cell.
this value can either be an absolute (the default) or percentage value. The absolute
value is a number, which represents the amount of memory in gigabytes; the
percentage value is any number followed by the character %.
Example
• To configure 1 GB of memory as CLM on cell 6 of nPartition 0, the command is
# parmodify -p0 -m 6::::1
For the parmodify change to take effect, you need to reboot the nPartition. This can be done
by MON> reboot.
Configuring CLM Notes
IMPORTANT: The HP-UX operating system does not support a 100% CLM configuration in an
nPartition. Some memory must be configured as ILM to support HP-UX (whether in a vPars
environment or not).
• It is possible that a server’s NVRAM (non-volatile RAM) values for ILM and CLM can change
due to a firmware update or a previous systems administrator. Verify the NVRAM values.
• Any memory that is not configured as CLM remains ILM.
• You need to be sure to leave enough ILM memory for your virtual partitions to boot, as specified
in your vPars database. Also, on PA-RISC not all memory can be configured as CLM in an
nPartition. You need to allow ILM memory for the vPars Monitor to boot and for all the OS
kernels to boot; excluding the first granule, a portion of which is used by the vPars Monitor,
there must be at least one entire granule that exists below the 2 GB limit for each virtual
partition. These granules below the 2 GB limit are used by the kernel of each virtual partition.
• nPartition configuration rules limit the minimum amount of configured CLM memory for a cell.
If you have any CLM on a cell, it must be at least 512 MB.
• When performing parmodify commands within a vPars environment, you will see only the
cells that are within the nPartition running vPars. If you wish to add cells from outside the
nPartition, you will need to be in standalone (PA-RISC) or nPars (Integrity) mode to see the
other cells.
