Conﬁguring and enabling PRM on the command line

Conﬁguring PRM

Chapter 7 107

HIER Indicates the PRM group is a parent group in a

hierarchy and that it has no PRMID. The reserved

group names OTHERS and PRM_SYS cannot be parent

groups. Also, you cannot use PRMID 0 for a child

group. You can, however, use PRMID 1 for a child

group.

For information on hierarchical groups, see

“Hierarchical PRM groups” on page 38.

PSET Indicates the PRM group is a PSET PRM group. In this

case, SHARES is not used. Instead, use the CORES and

CORE_LIST ﬁelds to specify the cores assigned to the

PSET.

NOTE When you have PRM groups based on PSETs enabled:

• Do not modify the PSETs manually using the

psrset command

• Do not adjust CPU counts in virtual partitions

using the vparmodify command

• Do not adjust Instant Capacity (iCAP), Temporary

Instant Capacity (TiCAP), or Pay Per Use resources

using the icapmodify or ppuconfig commands

• Do not perform online cell operations, using

parolrad or any other interface, while PRM is

managing the system (For more information, see

the WARNINGS section in the prmconﬁg(1)

manpage.)

SHARES Speciﬁes the FSS PRM group’s CPU shares. Shares are

integer values ranging from one to MAXINT.

An FSS PRM group’s resource percentage is

determined by its number of shares relative to the sum

of the shares for its set of sibling groups. For more

information on shares, see “Resource allocation” on

page 34. If the total number of shares is 100, each

group’s shares represent the percent of CPU resources

that the group receives.
