parcreate(1M)

use_on_next_boot

speciﬁes whether the blade 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 CPU

selftest failure or a DIMM de-allocation failure happens during the blade

activation, then this ﬂag is used by the system ﬁrmware to determine whether

or not and how the blade should be integrated into the nPartition at boot time.

The valid failure_usage values for blades are:

ri reactivate with memory interleave. Speciﬁes to integrate the

blade as it would normally be integrated. This is the default.

deconfig reactivate the nPartition with the blade excluded from activation.

slm_value

speciﬁes the amount of the memory that will be conﬁgured as Socket Local

Memory (SLM) for the blade. The slm_value speciﬁed using

-a or -c option

takes precedence over the slm_value speciﬁed using the

-L option. The

slm_value speciﬁed by

-L

option is applied to all blades for which an

slm_value has not been speciﬁed with the

-a or -c options. If slm_value is

not speciﬁed, the OS speciﬁc default is applied. The size of SLM allocated is a

best attempt to meet the user requested value. In addition, depending on plat-

form architecture, some amount of ILM may be allocated even when 100%

SLM is requested. The slm_value can be expressed in two forms:

• 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 per-

centage is applied each time the nPartition boots, thus resulting in a

different value if the working memory in the blade is different. For exam-

ple, 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 nPartition, 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 allocated 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]

Speciﬁes I/O bays to be assigned to 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 format

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.
