The value of tHsmdaSchedulerPlcyLvl2GrpId specifies the group this
HSMDA scheduler policy level belongs to. If the value is '0', this
level is not assigned to a scheduler policy group. This object may not
be set simultaneously with tHsmdaSchedulerPlcyLvl2Rate.
Setting tHsmdaSchedulerPlcyLvl2GrpId to non-default value while
tHsmdaSchedulerPlcyLvl2Rate is non-default, results in the level being
added to the group and tHsmdaSchedulerPlcyLvl2Rate being set to
default.
Setting tHsmdaSchedulerPlcyLvl2GrpId to default value results in the
level being removed from any group and tHsmdaSchedulerPlcyLvl2WgtInGrp
being set to default.
