Configuring WLM
Defining the PRM components (optional)

where
group Is the workload group name.
You cannot specify a PSET group in a disks statement.
volume Names a logical volume group. volume must begin with
/dev/v to be recognized.
shares Is an integer value greater than or equal to 0. shares
translates to a percentage of the disk bandwidth when
dividing it by the number of disk bandwidth shares
assigned to all the workload groups for the given
volume group.
If one FSS workload group has disk shares for a volume
group, then all FSS workload groups must have disk
shares for that volume group.
Here is an example disks statement:
disks = OTHERS : /dev/vg01 1,
finance : /dev/vg01 35,
sales : /dev/vg01 35,
marketing : /dev/vg01 29;
Specifying a group’s minimum CPU resources
(optional)
You can assign workload groups a minimum number of CPU shares. This
minimum is a hard lower limit (assuming the sum of the gmincpu values
is less than or equal to the total CPU resources); the group receives less
than this minimum only if it has no active SLOs and transient_groups
is set to 1. (However, if the group is associated with a process map, it
remains active and continues to receive the minimum shares even if it
has no active SLOs.) This hard limit is different from the mincpu value in
slo structures, which merely specifies the minimum CPU request the
SLO controller can make.
To specify the minimum number of CPU shares a group receives, use the
gmincpu keyword in the prm structure, according to the following syntax:
gmincpu = group : min [, ...];
where
group Is the workload group name.
