Unassigning (Removing) Cells from an nPartition

HP System Partitions Guide: Administration for nPartitions, rev 5.1

• Removing an Inactive Cell

When removing an inactive cell from an nPartition you do not need to

specify the -B option to parmodify and do not need to perform a

reboot for reconﬁg of the cell’s nPartition.

When you use parmodify to remove an inactive cell, the cell is

immediately unassigned from its nPartition.

If you specify the -B option when removing an inactive cell from an

inactive nPartition, then the cell is immediately removed and the

modiﬁed nPartition is booted past its inactive ready for reconﬁg state

and becomes an active nPartition.

For example, the following command removes cell 2 from partition 0.

Because cell 2 is inactive, it is immediately unassigned.

# parmodify -p0 -d2

Command succeeded.

Step 3. As needed, perform a reboot for reconﬁg (shutdown -R) of the nPartition

being modiﬁed.

You must perform a reboot for reconﬁg if you have removed an active cell

or have speciﬁed the -B option when modifying an active nPartition.

See the Reboot for Reconﬁg Guidelines for Removing Cells on page 274

for details on when to perform a reboot for reconﬁg.

This reboot for reconﬁg enables the cell removal to complete and the

Complex Proﬁle to be unlocked.

If you have removed an active cell and you did not specify the -B option

to parmodify, then the nPartition will remain inactive in the

ready for reconﬁg state after you perform the reboot for reconﬁg. To

make the inactive nPartition active, use the service processor Command

menu’s BO (boot) command.
