The value of tHsmdaSchedulerPlcyLvl7GrpId 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 tHsmdaSchedulerPlcyLvl7Rate.
Setting tHsmdaSchedulerPlcyLvl7GrpId to non-default value while
tHsmdaSchedulerPlcyLvl7Rate is non-default, results in the level being
added to the group and tHsmdaSchedulerPlcyLvl7Rate being set to
default.
Setting tHsmdaSchedulerPlcyLvl7GrpId to default value results in the
level being removed from any group and tHsmdaSchedulerPlcyLvl7WgtInGrp
being set to default.
