  • Cloud Volumes ONTAP (CVO)
  • HA 对
  • Microsoft Azure
  • AIQUM

问题

  • AIQUM 发现新 Azure CVO HA 对失败,出现以下超时错误:

 

ERROR [default task-5317] c.n.o.n.e.EmsZapiManager (EmsZapiManager.java:858) - Failed ZAPI call ems-event-catalog-get-iter: netapp.manage.NaProtocolException: Unexpected HTTP response: 502 Bad Gateway

  • 数据 SVM 未通过 Azure DNS 的"dns check",在 MGWD.log 上出现以下错误:
[kern_mgwd:info:3710]: ERR: MGWD::NSLIBC: NSLIBC: __res_nsend(), ../../../../../../src/lib/libc/resolv/res_send.c:813, Vsid = 5 Timed out while connecting to DNS server: <DNS_SERVER_IP_1> via Source Address <DATA_SVM1_LIF_IP>. Error: Operation timed out

原因

使用 ONTAP CLI 手动删除 CVO 默认数据 SVM,导致 ONTAP 中的默认数据 SVM 负载平衡器规则被删除,以及在 CVO HA 集群上创建的其他 SMB 数据 SVM 不满足所有 Azure 要求。

解决方案

  1. 在 Azure 中部署 新的 CVO HA 对
  2. 如果需要, 请重命名 由 CVO HA 部署创建的默认数据 SVM(不要将其删除)
  3. 在 Azure 中为 CVO HA 对创建其他数据 SVM 
  4. 在 AIQUM 中发现  CVO HA 集群
