SnapCenter 备份因"可能需要添加存储系统"而失败、并具有多个LIF

适用场景

• 适用于 Microsoft Windows 4.1 的 SnapCenter 插件
• SVM具有多个SVM管理LIF

问题描述

• SnapCenter 备份失败、并显示以下错误。

Storage system(s) may need to be added, also ensure that the associated host is in a connected state.

• SMCore_<JABID>.log显示由于SmDiscoverResourcesResponse而返回错误。

示例：

DEBUG SMCore_<JOBID> PID=[<PID>] TID=[<TID>] Response Data: **************************** 
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><SmDiscoverResourcesResponse><Result><_message>Unable to get storage details for datastore <DATASTORE> with managed object reference <DATASTORE>. Storage system(s) may need to be added, also ensure that the associated host is in a connected state.</_message><_errorCode>-1</_errorCode></Result><TotalCount>0</TotalCount><DisplayCount>0</DisplayCount></SmDiscoverResourcesResponse>
DEBUG SMCore_<JOBID> PID=[<PID>] TID=[<TID>] Discover resource enumeration returns null or empty
 

• SnapDriveSALDebug.log为无法从SnapCenter 访问的SVM管理LIF显示"不知道此类主机"。

示例：

Verbose SAL PID=[<PID>] TID=[<TID>] ++NetworkResourceIdCache::ResolveWithDns
