适用场景

  • ONTAP 9
  • 存储池

问题解答

  • 如果仅将一个节点分配给存储池的一个完整的未分区SSD备用磁盘、则在接管事件期间、您可以收到此警报、因为接管节点会重播正在重新启动的节点的事件。
Tue Feb 01 11:14:22 EST [ntap-clus-01: config_thread: callhome.spares.low:error]: Call home for SPARES_LOW
Tue Feb 01 11:15:00 CST [ntap-clus-01: monitor: monitor.globalStatus.critical:EMERGENCY]: This node has taken over ntap-clus-02. There are not enough spare disks.
 
  • 示例:
    • 节点A拥有唯一未分区的SSD备用磁盘。
    • 节点A接管节点B由于节点B没有存储池的任何备用磁盘、因此节点A会重放此消息。
    • 节点B完成升级、并执行交还。
    • 节点B接管节点A由于节点B仍不拥有任何备用磁盘、因此节点B会报告此消息。

 

  • 这是预期行为、不会影响系统。
 
 

追加信息

您只能将一个备用SSD用于存储池。如果存储池为HA对中两个节点所拥有的混合聚合提供了分配单元、则备用SSD可以归任一节点所有。但是、如果存储池仅为HA对中某个节点所拥有的混合聚合提供分配单元、则SSD备用磁盘必须属于同一节点。
