由于此原因，无法向 OnCommand Unified Manager 添加新集群 到无效名称

适用于

• Active IQ Unified Manager 9.6+%
• OnCommand Unified Manager 9.5+

问题

• 在尝试向 Unified Manager （ UM ）添加新集群时，如果接受集群安全证书，则会显示以下错误：

  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.

• server_acq.log UM 服务器上的将包含以下错误：

  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 mlog/audit.log 集群上的文件（或 AUDIT-MLOG-TXT.GZASUP 中的部分）时，请求将显示拒绝的主机名
