适用场景

  • ONTAP 9
  • 所有 FAS 系统
  • 所有 AFF 系统
  • 启用 auto-giveback 了和 auto-giveback-after-panic选项的系统

问题解答

  • auto-giveback 此选项包括用于防止发生重复接管和自动交还事件的代码
  • 默认值是在 60 分钟的时间范围内尝试两次自动交还
  • 60 分钟计数器从接管时刻开始,只有当配对 waiting-for-giveback 节点处于状态时,才会尝试交还。
  • 可以从 advanced 权限级别查看此设置
Cluster::*> set adv
Cluster::*> storage failover show -node <node name> -fields attempts,attempts-time
node         attempts attempts-time
------------------ -------- -------------
Node-01        2     60
  • -attempts 选项用于指定节点在设置的时间内尝试自动交还的次数
  • -attempts-time 选项用于指定 -attempts 参数设置的时间段
