Data Domain：检测到 NVRAM 故障 |错误或故障情况

Summary: NVRAM 及其备用电池组 （BBU） 是 Data Domain 数据无损体系结构的关键组件。Data Domain作系统 （DDOS） 监视这些组件。如果发生硬件故障，DDOS 将生成警报，必须立即解决该警报以维护系统完整性。

Symptoms

⚠️ 重要提示：请勿更换 NVRAM 卡或 BBU，除非 DDOS 已发布指示故障的警报。不建议主动更换。

适用对象：

  • 所有 Data Domain 系统
  • 所有 DDOS 软件版本

可能的警报：

  • NVRAM-00001: File system is disabled due to a problem with the NVRAM subsystem
  • NVRAM-00002: Battery at low charge and not charging
  • NVRAM-00003: Excessive PCI or memory errors
  • NVRAM-00201: Hardware fault detected with NVRAM card
  • NVRAM-00202: Hardware fault detected with NVRAM remote battery
  • NVRAM-00204: Invalid condition detected with NVRAM battery

Cause

DDOS 持续监视 NVRAM 子系统。当检测到 NVRAM 卡或 BBU 中出现故障时，它会发布警报。
警报通常包括诊断详细信息，但如果更换组件无法解决问题，则可能需要进一步调查。

Resolution

解决警报通常涉及更换 NVRAM 卡或 BBU（如果未集成）。执行以下步骤：

  1. 生成支持包
  2. 向您的支持提供商提出服务请求。

有用的 CLI 命令：

  • # alerts show current        # Check for active NVRAM or battery alerts
# system show nvram          # Review card errors and battery status
# system show hardware       # Confirm NVRAM card presence

 

注意：电池电量低于 100% 是正常的。DDOS 通过定期放电和充电来管理电池运行状况。
