The value of tHsmdaSchedulerPlcyLvl8GrpId 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 tHsmdaSchedulerPlcyLvl8Rate.
Setting tHsmdaSchedulerPlcyLvl8GrpId to non-default value while
tHsmdaSchedulerPlcyLvl8Rate is non-default, results in the level being
added to the group and tHsmdaSchedulerPlcyLvl8Rate being set to
default.
Setting tHsmdaSchedulerPlcyLvl8GrpId to default value results in the
level being removed from any group and tHsmdaSchedulerPlcyLvl8WgtInGrp
being set to default.
