環境

  • ONTAP 9
  • SnapMirror Synchronous(SM-S)およびSnapMirrorの非同期ファンアウト構成

問題

  • SnapMirror Asynchronous and SnapMirror Synchronous(SM-S)ファンアウト構成:
Async-SRC                Async-DST
cluster1:node1/src1 cluster1    :node2/dst1
cluster1:node2/src2 cluster1    :node1/dst2
 
同期- SRC                 同期- DST
cluster1:node1/src1 Cluster2    :node1/dst1
cluster1:node2/src2 Cluster2    :node2/dst2
  • Sync SnapMirror関係(Sync-DST)のデスティネーション側でsms.fanout.comm.snap.deletedメッセージが報告されている。
例:
11/6/2024 19:23:45 node1 ALERT sms.fanout.comm.snap.deleted: SnapMirror Synchronous operation 'Update' for relationship 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' has cleaned up some of the old base Snapshot copies between the synchronous source and synchronous destination, which could result in no common Snapshot copy existing between the synchronous and asynchronous destinations.
 
  • 非同期DSTと同期DSTのSnapMirror共通Snapshotの数を比較すると、一部のSnapMirror 共通Snapshotは同期DSTにしか存在しません。
  • ASUPによれば、Async SnapMirror関係のステータスはBroken-offと表示されます。

注:
ファンアウト関係はないが、 逆の関係または  削除されたファンアウト関係でソースボリュームに古いSnapshot Snapshot Snapshotがある場合があります。
