The value of tHsmdaSchedulerPlcyLvl6GrpId 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 tHsmdaSchedulerPlcyLvl6Rate.
Setting tHsmdaSchedulerPlcyLvl6GrpId to non-default value while
tHsmdaSchedulerPlcyLvl6Rate is non-default, results in the level being
added to the group and tHsmdaSchedulerPlcyLvl6Rate being set to
default.
Setting tHsmdaSchedulerPlcyLvl6GrpId to default value results in the
level being removed from any group and tHsmdaSchedulerPlcyLvl6WgtInGrp
being set to default.
