an nPartition that has been powered on, or if the user has set the

use_on_next_boot

attribute

of the blade to be false.

I/O Enclosures and I/O Bays

HP Superdome 2 I/O Expansion Enclosures (IOX enclosures) contain two bays, each of which

may be independently assigned to nPartitions. I/O bays are not directly attached to blades on

HP Superdome 2 servers - the I/O bays in an IOX have to be assigned to specific partitions, thus

allowing more flexibile I/O assignments. Therefore, in addition to blades, every nPartition can

have I/O explicitly assigned to it. The resource path format for specifying an I/O bay is

IO_enclosure#/iobay#

. I/O bays are assigned using the

-a

io:enclosure#/iobay#:[use_on_next_boot]

option of the

parcreate

and

parmodify

commands.

NOTE:

There are some I/O slots on the blade itself. These are two dual-port LAN on Motherboard

modules (LoMs), 3 mezzanine card slots, and the blade's iLO port. The mezzanine slots are

assigned the slot numbers 1, 2, and 3. The LoMs are assigned the slot numbers 4 and 5. The iLO

is assigned slot number 6.The mezzanine cards are not supported at the first release. If the I/O

on the blade is not sufficient for the nPartition, additional I/O may be assigned by using the IOX

expansion enclosure.

Finding the Resource Path of I/O

The resource path of your blade-based I/O components and I/O bay based I/O slots can be found

through the OA CLI or through EFI commands. Using the HP Superdome 2 OA, the command

parstatus

–

c {enclosure#/blade#}

–

V

. For example,

parstatus -c1/2 -V

command

reports the path of the LoMs on blade 2 in enclosure 1. Using EFI, the

info io

command returns

the results of all resources paths to all I/O. Following is a sample output of the

info io

command

for a dual ported LoM (enclosure 1, blade 2, I/O slot 5)

1/2/5 04/80 00/00 14E4/1650 103C/7105/00 Network Controller - Ethernet control

1/2/5 04/80 00/01 14E4/1650 103C/7105/00 Network Controller - Ethernet control

For the same LoMs the resource path listing using the

parstatus -c1/2

is shown below. LAN

on Motherboard NICs are numbered 4 and 5, as shown below:

nPartition Properties

This section describes the commonly used nPartition properties you work with when performing

nPartition administration tasks.

The following nPartitions details are covered here:

•

“Partition Names”

•

“Partition Numbers”

•

“Hyperthreading”

•

“Socket Local Memory”

Partition Names

Specifies the name of the nPartition. The

parcreate

—

P name

command is used to create an

nPartition with a

name

associated to it. An nPartition name must have at least one of the following

non-numeric characters: a-z, A-Z, dash (-), under-score (_), or period (.). No other non-numeric

character is allowed in an nPartition name. An nPartition name with the same format as the

default name can only be specified if the specified name matches the nPar number. If name is
