PowerFlex Manager — SO 节点更新在功能 update_clc_node_agent 中失败

情况说明

• 环境：高可用性 （HA） CloudLink Center 设备
• 问题：SO 资源组仅列出两个预期 CLC VM 中的一个。
• 症状：升级 SO 节点失败，理由是节点不在 PMM 中。

此情形表示升级失败的触发点。下面是一个示例，说明了在运行 update_clc_node_agent 功能：

运行状况良好的堆栈示例：

此外，升级作业日志还会捕获任务失败的确切时刻：

影响

无法升级 SO 节点。

日志指示 PowerFlex Manager无法继续执行update_clc_node_agent任务，因为它无法在两个 CLC 设备中识别正确的“主”。这显示在 deployment.logs 的错误行中：

ERROR [2024-12-19T13:35:51.093230] 19552: service_deployment.rb:5535:in `process_firmware_update': Encountered an error during firmware update: NoMethodError: undefined method `[]' for nil:NilClass

1. 尝试更新服务详细信息作 

   1. 在受影响的服务上启动“Update Service Details”作。

2. 在向导中验证资源清册摘要

   1. 在此过程中，向导应显示资源清册摘要，指示正在移除一个 CLC 设备，并正在添加另一个 CLC 设备。
   2. 这将确认当前 CLC 不是主 CLC，并且要添加的设备是正确的主
       

3. 完成更新服务详细信息流程

   1. 按照向导的指导完成Update Service Details作。

4. 继续升级

   1. 重试升级。它现在应该可以正常进行。
