blade_path

speciﬁes the blade resource path. It can be speciﬁed in short, medium, or long

format. For example, the blade located in enclosure 1, slot 3 is identiﬁed in

the short format as 1/3, in the medium format as

blade-1/3, or in the long

format as

enclosure1/blade3

-d io:iobay_path Deletes the speciﬁed I/O bay from the nPartition. To delete multiple I/O bays from

the nPartition, multiple

-d options should be used. If the I/O bay which is being

deleted is an active I/O bay then after the execution of the parmodify command the

user must reboot the nPartition for the change to take effect. For an nPartition run-

ning virtual partitions, individual virtual partitions have to be shut down and the

nPartition rebooted for the change to take effect. Deletion of inactive I/O bay does

not require a reboot of the nPartition.

iobay_path

speciﬁes the I/O bay resource path. It can be speciﬁed in short, medium, or

long format. For example, I/O bay 1 with enclosure 7 can be speciﬁed in the

short format as

7/1, in the medium format as

iobay-7/1, or in the long for-

mat as

enclosure7/iobay1

-m blade :blade_path :[blade_type]

:[use_on_next_boot]

:[failure_usage]

: [slm_value ]

Modiﬁes attributes of a blade already assigned to the nPartition. Please refer to the

explanation of the

-a blade option for details of the different ﬁelds in this option

argument.

-m io:iobay_path:[use_on_next_boot][

:failure_usage]

Modiﬁes attributes of an I/O bay already assigned to the nPartition. Please refer to

the explanation of the

-a io option for details of use_on_next_boot and failure_usage

ﬁelds in this option argument.

-B Speciﬁes to reboot the nPartition now. The default is not to boot. This option is

useful only if the

-a option or the -d option or a slm_value has been speciﬁed.

-G memory_granularity_type

:size

Speciﬁes the memory granularity (ILM or SLM) in megabytes (MB) for the nParti-

tion. The default memory granularity value would depend on the operating system

type speciﬁed by the user through

-O option.

-L slm_value Used with -a and -m options to specify the amount of the memory that will be used

as Socket Local Memory (SLM) per blade.

Use of the

-L option without either the -a or -m option results in no action being

taken.

However, any slm_value speciﬁed using the

-a or -m options overrides the

-L

option.

Please refer to the explanation of the

-a or -m option for details of the slm_value

formats.

The default memory settings would depend on the operating system type speciﬁed

by the user through the

-O option.

The default memory setting is also dependent on the boot mode of the nPartition.

System may choose to have a different default memory setting for the nPartition in

virtual partitions mode for ease of virtual partition conﬁguration. However, if user

has speciﬁed a value for memory setting, that will be applied independent of the

mode of operation.

-M type:max_value Speciﬁes maximum number of blades or virtual partitions allowed in an nPartition.

The nPartition will not be allowed to have more than the max_value for the type

speciﬁed. The valid values for types are case-insensitive blade and vpar.

By default, platform supported max values for blades per nPartition and virtual

partitions per nPartition are allowed. User speciﬁed value cannot be greater than

platform supported max values.

-N next_boot_mode Speciﬁes whether the nPartition has to be booted as a single partition (nPars mode)

capable of running only a single operating system (OS) instance or as one or more

virtual partitions (vPars mode) as deﬁned in the virtual partition database in the
