Table 7-1 Hardware Management Task Summaries (continued) Task Summary "Enabling and Disabling Hyper-Threading on • CAUTION: Some operating systems do not support Hyper-Threading. Problems can Dual-Core Intel® occur when running an OS that does not support Hyper-Threading on an nPartition Itanium® 2 Processors" that has Hyper-Threading enabled. • NOTE: You must reset an nPartition when changing its Hyper-Threading status. Hyper-Threading will not be enabled or disabled until after the nPartition is reset. • EFI Shell: cpuconfig threads command. cpuconfig threads on to schedule Hyper-Threading to be enabled after the nPartition is reset. cpuconfig threads off to schedule Hyper-Threading to be disabled after the nPartition is reset. • HP-UX: setboot command. setboot -m on to schedule Hyper-Threading to be enabled after the nPartition is reset. setboot -m off to schedule Hyper-Threading to be disabled after the nPartition is reset. • Enhanced nPartition Commands: parmodify -pn -T [y|n] command to enable (-T y) or disable (-T n) Hyper-Threading for the specified nPartition (-pn, where n is the nPartition number) the next time the nPartition is reset. • Partition Manager: When performing the Create nPartition or Modify nPartition tasks, select or deselect the Enable Hyper-Threading check box on the Configure Memory tab to configure the Hyper-Threading status the next time an nPartition is reset. See "Enabling and Disabling Hyper-Threading on Dual-Core Intel® Itanium® 2 Processors" (page 218). "Configuring and Deconfiguring Memory (DIMMs)" • NOTE: DIMMs operate either in ranks of four or echelons of two, depending on the memory architecture of the server. When you deallocate a DIMM, all other DIMMs in the rank or echelon also will not be used the next time the nPartition boots. Each rank or echelon is numbered (0, 1, 2, and so on up to hexadecimal number F as needed). The DIMMs in the rank or echelon are lettered (A to D). For example, rank 0 includes DIMMs 0A, 0B, 0C, and 0D; echelon 1 has DIMMs 1A and 1B. After the DIMM configuration is changed the nPartition in which it resides must be rebooted to use the new configuration. • BCH Menu: Service Menu, DIMMDEALLOC command. DIMMDEALLOC cell dimm OFF deconfigures the specified DIMM (dimm) on the cell (cell) indicated. DIMMDEALLOC cell dimm ON configures the DIMM on the cell. Use DIMMDEALLOC cell to display the DIMM configuration for the specified cell. • EFI Shell: dimmconfig command. dimmconfig cell dimm OFF deconfigures the specified DIMM (dimm) on the cell (cell) indicated. dimmconfig cell dimm ON configures the DIMM on the cell. Use dimmconfig cell to display the DIMM configuration for the specified cell. See "Configuring and Deconfiguring Memory (DIMMs)" (page 220). "Complex Health Analysis of a Server" • Complex health analysis provides both an evaluation of the complex hardware and an evaluation its nPartition configurations. • Partition Manager: Use the Complex→Analyze Complex Health action. See "Complex Health Analysis of a Server" (page 222). 204 Managing Hardware Resources

Summary

Task

•

CAUTION:

Some operating systems do not support Hyper-Threading. Problems can

occur when running an OS that does not support Hyper-Threading on an nPartition

that has Hyper-Threading enabled.

•

NOTE:

You must reset an nPartition when changing its Hyper-Threading status.

Hyper-Threading will not be enabled or disabled until after the nPartition is reset.

•

EFI Shell:

cpuconfig threads

command.

cpuconfig threads on

to schedule Hyper-Threading to be enabled after the

nPartition is reset.

cpuconfig threads off

to schedule Hyper-Threading to be disabled after the

nPartition is reset.

•

HP-UX:

setboot

command.

setboot -m on

to schedule Hyper-Threading to be enabled after the nPartition is

reset.

setboot -m off

to schedule Hyper-Threading to be disabled after the nPartition

is reset.

•

Enhanced nPartition Commands:

parmodify -p

-T [y|n]

command to enable

(

-T y

) or disable (

-T n

) Hyper-Threading for the specified nPartition (

-p

, where

is the nPartition number) the next time the nPartition is reset.

•

Partition Manager: When performing the

Create nPartition

Modify nPartition

tasks,

select or deselect the

Enable Hyper-Threading

check box on the

Configure Memory

tab to configure the Hyper-Threading status the next time an nPartition is reset.

See

“Enabling and Disabling Hyper-Threading on Dual-Core Intel® Itanium® 2

Processors” (page 218)

“Enabling and Disabling

Hyper-Threading on

Dual-Core Intel®

Itanium® 2 Processors”

•

NOTE:

DIMMs operate either in ranks of four or echelons of two, depending on the

memory architecture of the server. When you deallocate a DIMM, all other DIMMs

in the rank or echelon also will not be used the next time the nPartition boots.

Each rank or echelon is numbered (0, 1, 2, and so on up to hexadecimal number F as

needed). The DIMMs in the rank or echelon are lettered (A to D). For example, rank

0 includes DIMMs 0A, 0B, 0C, and 0D; echelon 1 has DIMMs 1A and 1B.

After the DIMM configuration is changed the nPartition in which it resides must be

rebooted to use the new configuration.

•

BCH Menu: Service Menu,

DIMMDEALLOC

command.

DIMMDEALLOC

cell dimm

OFF

deconfigures the specified DIMM (

dimm

) on the cell

(

cell

) indicated.

DIMMDEALLOC

cell dimm

configures the DIMM on the cell.

Use

DIMMDEALLOC

cell

to display the DIMM configuration for the specified cell.

•

EFI Shell:

dimmconfig

command.

dimmconfig

cell dimm

OFF

deconfigures the specified DIMM (

dimm

) on the cell

(

cell

) indicated.

dimmconfig

cell dimm

configures the DIMM on the cell.

Use

dimmconfig

cell

to display the DIMM configuration for the specified cell.

See

“Configuring and Deconfiguring Memory (DIMMs)” (page 220)

“Configuring and

Deconfiguring Memory

(DIMMs)”

•

Complex health analysis provides both an evaluation of the complex hardware and

an evaluation its nPartition configurations.

•

Partition Manager: Use the

Complex

→

Analyze Complex Health

action.
