問題

クラスタレベルのSnapshotポリシーが作成されると、リモートクラスタの同期先SVMに大量のSnapshotポリシーが作成されます（末尾が「-DR」）。

例：

ClusterA::> volume snapshot policy show
Vserver: mcc-8040-2n-A
             Number of Is
Policy Name        Schedules Enabled Comment
------------------------ --------- ------- ----------------------------------
default             3 true   Default policy with hourly, daily & weekly schedules.
   Schedule         Count    Prefix          SnapMirror Label
   ---------------------- -----    ---------------------- -------------------
   hourly            6    hourly          -
   daily            2    daily          daily
   weekly            2    weekly          weekly

default-1weekly         3 true   Default policy with 6 hourly, 2 daily & 1 weekly schedule.
   Schedule         Count    Prefix          SnapMirror Label
   ---------------------- -----    ---------------------- -------------------
