Managing nPartitions
Unassigning (Removing) Cells from an nPartition
HP System Partitions Guide: Administration for nPartitions, rev 5.1 275
In order to remove cells that are not assigned to the local nPartition, the
cells must be inactive (their “Actual Usage” must be “inactive”). You can
list the local nPartition by issuing the parstatus -w command.
To remove an active cell from its nPartition, you must do so when logged
in to HP-UX running on the cell’s nPartition.
Step 2. Remove the cell from the nPartition to which it is assigned by using the
parmodify -p # -d # ... command.
Specify the partition number (-p # ) and each cell (-d # ) that you want to
remove from the nPartition.
If removing multiple cells from an nPartition, specify each cell with a
separate -d # option on the same command line (such as: parmodify -p1
-d0 -d2... to remove cells 0 and 2 from partition number 1).
Slightly different procedures are required for removing active cells and
inactive cells. See the following information for details (Removing an
Active Cell and Removing an Inactive Cell).
When you are removing multiple cells from the local nPartition, if at
least one of the cells you plan to remove is currently active, then you
should follow the guidelines for removing active cells.
• Removing an Active Cell
You should specify the -B option to parmodify when removing an
active cell from the local nPartition if you want the nPartition to
become active following its reboot for reconfig.
For example, the following command removes cell 4 from partition 0
and the -B option ensures that the nPartition will be active following
its reboot for reconfig.
# parmodify -p0 -d4 -B
Cell 4 is active.
Use shutdown -R to shutdown the system to ready for
reconfig state.
Command succeeded.
#
You must perform a reboot for reconfig (shutdown -R) after you
issue the parmodify command to remove active cell(s) from the
nPartition. (This is covered in Step 3 that follows.)
