检查升级就绪情况

您可以使用 sfupgradecheck 命令确认集群是否已做好升级准备。此命令可验证待定节点、磁盘空间和集群故障等信息。如果您的管理节点位于非公开站点，则升级就绪检查需要元数据 JSON 文件才能成功运行。

1. 运行 sfupgradecheck 命令。
   sfupgradecheck -u <cluster-user-name> -p <cluster-password> MVIP

   请参见以下输入命令示例：

   sfupgradecheck -u admin -p admin 10.117.78.244

   示例输出如下。在此结果中，未显示任何错误，您可以进行升级。

     在此示例中，节点 1 的磁盘空间不足。您可以从此错误消息列出的知识库文章中查看更多信息。
   • HealthTools 已过时。请查看此错误消息，并注意升级检查失败。
     示例输出如下：

     sfupgradecheck failed: HealthTools is out of date: installed version: 2018.02.01.200 latest version: 2018.03.05.901.
     The latest version of the HealthTools can be downloaded from: https://mysupport.netapp.com/NOW/cgi-bin/software/ 
     Or rerun with the -n option

     如果出现这种情况，必须按照输出中所述的步骤进行操作。
   • 管理节点位于非公开站点上。请查看此消息，并注意升级检查失败。
     示例输出如下：

     sfupgradecheck failed: Unable to verify latest available version of healthtools.

     1. 如果出现这种情况，请获取 metadata.json 文件并将其保存在非管理节点计算机上，然后运行以下命令：sfupgradecheck -l --metadata=<path-to-metadata-json>

        有关详细信息，请参见适用于非公开站点的其他升级信息。

        在非公开站点上升级 Element 软件

     2. 运行以下命令以验证 HealthTools 是否为最新：sfupgradecheck -u <cluster-user-name> -p <cluster-password> MVIP
