由于名称无效，无法向 OnCommand Unified Manager 添加新集群

适用于

• Active IQ Unified Manager 9.6+
• ActiveIQ Unified Manager 9.16P2
• OnCommand Unified Manager 9.5+

问题描述

• 尝试将新群集添加到 Unified Manager (UM) 时，并且在接受群集安全证书后，它显示下列错误：

  Unable to add cluster data source. This can occur if the clocks on the systems are not synchronized and the Unified Manager HTTPS certificate start date is later than the date on the cluster, or if the cluster has reached the maximum number of EMS notification destinations.

• UM 服务器上的server_acq.log将包含以下错误：

  2020-10-01 12:09:33,130 ERROR [default task-2] c.o.s.a.s.AcquisitionFacadeUtil (AcquisitionFacadeUtil.java:171) - failed to register EMS: : com.netapp.oci.netapp.client.interfaces.data.EmsZapiManagerException: Invalid name. The name must start and end either with an alphanumeric or _(underscore) and must be in the length of 2 to 64 characters. The allowed special characters are _(underscore) and -(hyphen). (errno=27103)

• 在查看集群上的 mlog/audit.log 文件（或 ASUP 中的 AUDIT-MLOG-TXT.GZ 部分）时，请求将显示被拒绝的主机名
