适用场景

  • ONTAP 9
  • NetApp ONTAP FlexGroup
  • NetApp 卷加密 (NetApp Volume Encryption, NVE)
  • NetApp 聚合加密( NAE )

问题解答

以下限制适用于 fg create , rekey/conversion 和 expand :

fg create

  • 只有当所有目标 aggrs 都属于相同的加密类型( NAE 或非 NAE )时,才允许执行加密卷创建操作,不允许混合。
  • NAE aggrs 不允许创建纯文本 FG 卷。
  • 可以在 NAE 聚合和非 NAE 混合上创建 NVE 卷。
  • 如果指定了 -encrypt true ,则所有成分卷的类型均为 NVE 。目标 aggrs 可以是 NAE 聚合和非 NAE 聚合的组合。
  • 不支持 -encrypt false 。
  • 如果未指定任何内容,则会在脱网 NAE aggrs 上创建 NAE 卷。

fg重新设置密钥/转换

  • 如果任何成分卷的类型为 NAE ,则不允许原位重新设置密钥 / 转换。必须通过 vol-move 将 NAE 类型的成分卷转换为 NVE REST 卷类型。只有这样,才允许重新设置密钥 / 进行转换。

fg展开

  • 只有当新的目标聚合为 NAE 时,才允许向现有 FG ( NAE aggr )添加更多成员。如果新的目标聚合不是 NAE ,则此操作将失败。
