NetApp adopts Microsoft’s Business-to-Customer (B2C) Identity Management
Effective December 3 - NetApp adopts Microsoft’s Business-to-Customer (B2C) identity management to simplify and provide secure access to NetApp resources. For accounts that did not pre-register (prior to Dec 3) access to your NetApp data may take up to 1 hour as your legacy NSS ID is synchronized to the new B2C identity.

适用场景

  • SnapCenter 服务器( SC ) 4.4 和 4.5
  • 适用于 Microsoft Exchange Server 的 SnapCenter 插件( SCE ) 4.4 和 4.5
  • Exchange DAG

问题解答

  • SC 首先会检索 DAG 节点,并使用命令检查每个节点是已启动还是已关闭 GetClusterMembersUsingWMI

<installation_path>\Program Files\NetApp\SnapCenter\SMCore\log\SMCoreService.log

DEBUG SMCore PID=[2908] TID=[24] Cluster node <node_name> state is eHostUp
DEBUG SMCore PID=[2908] TID=[24] Cluster node <node_name> state is eHostUp
DEBUG SMCore PID=[2908] TID=[24] Cluster node <node_name> state is eHostUp
DEBUG SMCore PID=[2908] TID=[24] Retrieving the cluster Nodes: [Completed]
DEBUG SMCore PID=[2908] TID=[24] GetClusterMembersUsingWMI - End

  • 然后,它会 按字母顺序列出节点,其中 DAG 所有者显示为第一个节点,而不管它是否为实际 DAG 所有者,请参见以下使用节点 A , B 和 C 的示例:

<installation_path>\Program Files\NetApp\SnapCenter\SMCore\log\SMCoreService.log

DEBUG SMCore PID=[2908] TID=[24] First Member Node: A; Member Nodes: A,B,C
DEBUG SMCore PID=[2908] TID=[24] It's a cluster scheduled request A.xxx.local, A is the owner of <DAG_name>
DEBUG SMCore PID=[2908] TID=[24] Cluster FQDN <DAG_FQDN>
 

追加信息

为 SC 提交 BURT 以获取正确的 DAG 所有者
