nPartition Administrator's Guide, Second Edition

3. Modify the nPartition core cell choices using the parmodify -p# -r#... command.
You can modify the core cell choices for the local nPartition or any remote nPartition in the
server complex.
Use the following command: parmodify -p# -r# -r#...
Specify the nPartition number (-p#) and the cell ID (-r#) for all cells you wish to designate
as core cell choices.
# parmodify -p0 -r2 -r0
Command succeeded.
#
The order in which you list the cells is the order in which the nPartition core cell choices are
established; the first cell listed is the first preferred core cell (choice 1), and the subsequent
cells are lower-priority core cell choices (choices 2 through 4, if specified).
