适用场景

  • 适用于VMware vSphere的SnapCenter插件(SCV) 4.x
  • 数据保护源 SVM 和目标 SVM 具有重复的数据 LIF IP 地址(VServer-DR/SVM-DR)
  • 数据存储区与 SMBC(SnapMirror 业务连续性)一起使用

问题描述

  • SCV 备份随机失败,因为它尝试连接目标 SVM 而不是源 SVM 来拍摄快照
  • SCV 慢跑日志显示错误:

[ERR] Failed to run a command New-NcSnapshotMulti
[DBG] ex.Message : Invalid input. Reason: Operation allowed only on Read_Write (RW) volumes. 
[DBG] ex.InnerException.Message : Invalid input. Reason: Operation allowed only on Read_Write (RW) volumes.

  • vmcontrol.log 表示在发生错误之前,NFS LIF 发现了与平常不同的 SVM

DEBUG <SCV> --- [359023572-29370] c.n.a.m.DatastoreStorageDetailsCache    : Storage footprint found for nfsLif <NFS_LIF> and exportPath <EXPORTPATH>:  ipAddress null vserverName <SVM> volumeName <VOLUMENAME> junctionPath <JUNCTIONPATH> isLocatedOnFGfalse
