parmodify2(1M)

For OA Based Partition Management Systems

parmodify2(1M)

• As a percentage (ratio). The percent number can be any number in the

range 0 - 100 with a sufﬁx of "%". This number will be rounded up to

12.5%, 25%, 37.5%, 50%, 62.5%, 75%, 87% or 100%. If the blade contains

less than 4 GB memory, then the percentage will be rounded to 25%, 50%,

75% or 100%. The speciﬁed percentage is applied each time the nPartition

boots, thus resulting in a different value if the working memory in the

blade is different. For example, a blade in an nPartition has 8 GB memory

and the user speciﬁes 50% SLM. When the nPartition boots, 4 GB of that

blade’s memory will be used as SLM. Later the user shuts down the nPar-

tition, adds another 8 GB memory to that blade. When the nPartition is

booted again, the blade now has 16 GB of memory, so 8 GB (50%) is allo-

cated as SLM.

• As an absolute number (default). This can also be optionally sufﬁxed by

"GB". The slm_value is interpreted as an absolute number of gigabytes of

memory. Numbers other than integers and halves are rounded up to the

nearest 0.5 GB. For example, 2.5 GB will not be rounded up. However 2.3

GB will be rounded up to 2.5 GB. For example, a blade in an nPartition

has 8 GB memory and the user speciﬁes 4 GB SLM. When the nPartition

boots 4 GB of that blade’s memory will be used as SLM. Later the user

shuts down the nPartition, adds another 8 GB memory to that blade.

When the nPartition is booted again, the blade now has 16 GB of memory,

but the SLM is still 4 GB.

-a io:iobay_path:[use_on_next_boot][

:failure_usage]

Assigns the speciﬁed I/O bay to the nPartition. To assign multiple I/O bays to the

nPartition, multiple

-a options should be used.

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

use_on_next_boot

speciﬁes whether the I/O bay will participate in a reboot. The valid values for

use_on_next_boot are:

y participate in reboot. This is the default.

n do not participate in reboot.

failure_usage

ﬁeld is used by system ﬁrmware when an nPartition is booted. If a failure

happens during the I/O bay activation, then this ﬂag is used by the system

ﬁrmware to determine whether or not and how the I/O bay should be

integrated into the nPartition at boot time. The valid failure_usage values for

I/O bay are:

ri speciﬁes to integrate the I/O bay as it would normally be

integrated. This is the default.

deconfig reactivate the nPartition with the I/O bay excluded from activa-

tion.

-c new_parspec_name

Creates a copy of an existing parspec. The source parspec can be speciﬁed by the -Z

or -p option. If -p option is speciﬁed, the current parspec of the nPartition

speciﬁed by -p is selected as source. The copy is given the speciﬁed

new_parspec_name name and is marked as an alternate parspec.

-d blade:blade_path Deletes the speciﬁed blade from the nPartition. To delete multiple blades from the

nPartition, multiple -d options should be used. If the blade which is being deleted

is an active blade then after the execution of the parmodify command, the user

must reboot the nPartition for the change to take effect. For an nPartition running

virtual partitions, individual virtual partitions have to be shut down and the nParti-

tion rebooted for the change to take effect. Deletion of inactive blades does not

require a reboot of the nPartition.
