AIQ Unified Manager 无法删除由 Commvault 触发的快照
适用场景
- Commvault IntelliSnap 11
- Active IQ Unified Manager 9.x
- ONTAP 9
问题描述
- Commvault 会根据自己的数据库轮换快照，但某些快照不会被删除
- 没有模式，所有随机的，多个集群都会受到影响
- Commvault 中没有错误，因为 Commvault 会将快照的到期标志成功发送到 Commvault
- Unified Manager 将删除这些快照
- Unified Manager 在主日志中没有错误，但 zapioutbound 日志会显示失败的请求

在集群命令行界面上删除失败，如下所示：
[cluster]::> snapshot delete -vserver [vserver] -volume [vol] -snapshot [snapshot name]
