SAS112 CLI 如何刪除特定快照？

原因分析:
Web管理不能刪除特定快照時，可用此方法。
解決方案:
命令：delete snapshot

說明：刪除特定快照。刪除唯一與快照關聯的所有資料後，快照池中的相關空間即可用。同時會刪除此快

照的所有計劃。

文法：delete snapshot [cleanup] [delete-priority standard-snapshot|volume-copy-snapshot|replication-snapshot|replicating-snapshot|common-sync-point-snapshot|only-sync-point-snapshot|queued-snapshot] [force] snapshots

參數：

cleanup 可選。刪除主卷的最後一個快照時，會自動將主卷轉換為標準卷，並刪除快照池。

delete-priority standard-snapshot|volume-copy-snapshot|replication-snapshot|replicating-snapshot|common-sync-point-snapshot|only-sync-point-snapshot|queued-snapshot 可選。可刪除的快照的優先順序。如果指定優先順序低於快照的優先順序，刪除操作將被阻止。這麼做的目標是為了防止意外刪除高優先順序的快照。此參數或 force 參數必須指定其一，但不能同時指定。

force 可選。覆蓋優先順序保護，強制移除指定的快照。此參數或 delete-priority 參數必須指定其一，但不能同時指定。

snapshots 要刪除的快照的名稱或序號。

樣本：

刪除複製操作正在使用的快照 SS1：

# delete snapshot delete-priority replicating-snapshot SS1

Info: Snapshot SS1 was deleted. (SS1)

通過指定較低優先順序嘗試刪除 common-sync-point 快照 SS2：

# delete snapshot delete-priority standard-snapshot SS2

Error: Snapshot priority has not been met.

強制移除快照 SS2：

# delete snapshot force SS2

Info: Snapshot SS2 was deleted. (SS2)

刪除三個標準快照：

# delete snapshot s1,s2,s3

Info: Snapshot s1 was deleted. (s1)

Info: Snapshot s2 was deleted. (s2)

Info: Snapshot s3 was deleted. (s3)
