Slightly different procedures are required for removing active cells and inactive cells. See the following information for details ("Guidelines for Removing an Active Cell" and "Guidelines for Removing an Inactive Cell"). If at least one of the cells you plan to remove is currently active, then follow the guidelines for removing active cells. • Guidelines for Removing an Active Cell Specify the -B option to parmodify when removing an active cell from an 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 after you issue the parmodify command to remove active cell(s) from the nPartition. (This is covered in the step that follows.) • Guidelines for 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 nPartition to which the cell is assigned. 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 shutdown 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. # 4. As needed, perform a reboot for reconfig of the nPartition being modified (HP-UX: shutdown -R; Windows: shutdown /r; Linux: shutdown -r time; OpenVMS: @SYS$SYSTEM:SHUTDOWN with an automatic system reboot). 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 "Reboot for Reconfig Guidelines for Removing Cells" (page 182) 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 shutdown for reconfig state after you perform the reboot for reconfig. To make the inactive nPartition active, use the BO (boot) command at the service processor Command menu. Procedure 6-9 Removing Cells from an nPartition (Partition Manager) You can remove cells from an nPartition by using Partition Manager. When using Partition Manager Version 1.0, select an nPartition, and use the Partition→Modify Partition action, Add/Remove Cells tab. When using Partition Manager Version 2.0, select an nPartition, and use the nPartition→Modify nPartition action, Add/Remove Cells tab. 184 Creating and Configuring nPartitions

Slightly different procedures are required for removing active cells and inactive cells. See

the following information for details (

“Guidelines for Removing an Active Cell”

and

“Guidelines for Removing an Inactive Cell”

If at least one of the cells you plan to remove is currently active, then follow the guidelines

for removing active cells.

•

Guidelines for Removing an Active Cell

Specify the

-B

option to

parmodify

when

removing an active cell from an 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 after you issue the

parmodify

command to

remove active cell(s) from the nPartition. (This is covered in the step that follows.)

•

Guidelines for 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 nPartition to which the cell is assigned.

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 shutdown 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.

As needed, perform a reboot for reconfig of the nPartition being modified (HP-UX:

shutdown

-R

; Windows:

shutdown /r

; Linux:

shutdown -r

time

; OpenVMS:

@SYS$SYSTEM:SHUTDOWN

with an automatic system reboot).

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

“Reboot for Reconfig Guidelines for Removing Cells” (page 182)

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 shutdown for reconfig state after you perform

the reboot for reconfig. To make the inactive nPartition active, use the

(boot) command

at the service processor Command menu.

Procedure 6-9 Removing Cells from an nPartition (Partition Manager)

You can remove cells from an nPartition by using Partition Manager.

When using Partition Manager Version 1.0, select an nPartition, and use the

Partition

→

Modify

Partition

action,

Add/Remove Cells

tab.

When using Partition Manager Version 2.0, select an nPartition, and use the

nPartition

→

Modify

nPartition

action,

Add/Remove Cells

tab.
