MDM 会记录类似于以下内容的崩溃。
21/05 14:35:26.924724 Panic in file /data/build2/workspace/ScaleIO-Common-Job@2/src/net/net_rpc.c, line 520, function netRpc_SendResponse, PID 30351.Panic Expression !(pMsg->msgSnd.rpcReq.context == 0) .
情况说明
来自迁移源或目标保护域 （PD） 的一个或多个 SDS 与系统断开连接。
影响
无法启动 vTree 迁移。
MDM 进程重新启动，可能触发 MDM 主要角色切换
根本原因
启动 vTree 迁移时，MDM 会检查源和目标 PD 中的所有 SDS 是否均已连接。
由于软件问题，此检查未完成。
按照设计，当无法完成作时，MDM 进程会自行终止。
解决方法
在 vTree 迁移启动之前，手动确认源和目标 PD 中的所有 SDS 均已连接。
受影响的版本
低于 3.0.1.1 的 PowerFlex OS 版本
已修复问题的版本
PowerFlex OS 3.0.1.1
