If you just wish to reduce them, you should be able to use these:

# parstatus -C (gives you the picture of what you have)

To remove You can only remove an entire cell board as I understand it. Have a (good) look at the parmodify man page for some clues. Also you might wish to check this document.

and look at the chapter on Unassigning (Removing) cells from an nPartition.

Just to avoid confusion, HP9000 SuperDome can support hard partitions (nPartitions) on cell board boundaries or soft partitions (vPars for virtual partitions) within a hard partition. With hardpartitions, the OS must be shutdown to remove or add cells. With vPars, floater CPUs can be deallocated without shutting down the virtual partition, but memory is fixed. Are you using hard partitions?
