命令：delete snapshot

说明：删除特定快照。删除唯一与快照关联的所有数据后，快照池中的相关空间即可用。同时会删除此快

照的所有计划。

语法：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

参数：

cleanup 可选。删除主卷的最后一个快照时，会自动将主卷转换为标准卷，并删除快照池。

delete-priority standard-snapshot|volume-copy-snapshot|replication-snapshot|replicating-snapshot|common-sync-point-snapshot|only-sync-point-snapshot|queued-snapshot 可选。可删除的快照的优先级。如果指定优先级低于快照的优先级，删除操作将被阻止。这么做的目标是为了防止意外删除高优先级的快照。此参数或 force 参数必须指定其一，但不能同时指定。

force 可选。覆盖优先级保护，强制删除指定的快照。此参数或 delete-priority 参数必须指定其一，但不能同时指定。

snapshots 要删除的快照的名称或序列号。

示例：

删除复制操作正在使用的快照 SS1：

# delete snapshot delete-priority replicating-snapshot SS1

通过指定较低优先级尝试删除 common-sync-point 快照 SS2：

# delete snapshot delete-priority standard-snapshot SS2

Error: Snapshot priority has not been met.

强制删除快照 SS2：

# delete snapshot force SS2

Info: Snapshot SS2 was deleted. (SS2)

删除三个标准快照：

# delete snapshot s1,s2,s3

Info: Snapshot s1 was deleted. (s1)

Info: Snapshot s2 was deleted. (s2)
