症状

SRA 命令“discoverDevices”失败。有关详细信息的常规错误检查日志。

找不到复制会话故障切换快照 ID。

原因

当 PowerStore 设备上有超过 100 个复制会话时，会出现此问题。

解决方案

修复

此问题的解决方法是在 PowerStore 存储复制适配器 （SRA） 版本 2.2 的下一个版本中。
 

解决方法

将每个 PowerStore 设备的复制会话数限制为 100 个。

其他信息

从 SRM 日志中识别问题


默认情况下，REST API 调用将返回一百个对象。日志显示返回了第一个 100 默认发现，并带有 HTTPS 响应代码：206（找到分页的数据）。100-134 的范围随 HTTPS 响应代码一起返回：400.分页请求缺少标题“DELL-VISIBILITY=Internal”。这会导致发现设备故障。
