问题

cluster peer health show该命令显示session_reachableData Ping集群对等关系中一个或多个节点对的状态。在以下示例中、本地节点 NetApp -02 报告session_reachableData Ping IT 与远程节点 DRNetApp -01 之间的状态。

NETAPP01::> cluster peer health show
Node     Cluster-Name          Node-Name

       Ping-Status         RDB-Health Cluster-Health Availability
---------- --------------------------- --------- --------------- ------------
NETAPP01-01
      DRNETAPP01           DRNETAPP01-01
       Data: interface_reachable
       ICMP: interface_reachable  true    true       true
                     DRNETAPP01-02
       Data: interface_reachable
       ICMP: interface_reachable  true    true       true
NETAPP01-02
      DRNETAPP01           DRNETAPP01-01
       Data: session_reachable
       ICMP: interface_reachable  true    true       true
                     DRNETAPP01-02
       Data: interface_reachable
       ICMP: interface_reachable  true    true       true
4 entries were displayed.

session_reachable Data Ping 一个或多个节点对的状态将导致集群对等关系报告Partial可用性,如cluster peer show命令中所示。
NETAPP01::> cluster peer show
Peer Cluster Name      Cluster Serial Number  Availability   Authentication
------------------------- ---------------------  --------------  --------------
DRNETAPP          0-00-000000       Partial      ok

Partial集群对等关系的可用性可能会阻止管理软件中的某些操作,如 OnCommand System Manager 或 7- 模式过渡工具( 7MTT )。

session_reachableData Ping在大多数情况下、问题将是间歇性的、 SnapMirror 将继续运行; 但是session_reachable,在集群会话管理器 (CSM) 连接失败、集群对等连接中断或 SnapMirror 中止时,状态可能也会出现,例如,可以通过event log show命令查看以下日志:
