问题描述

尝试列出资源组中的数据存储库时出现与Java相关的异常：

DEBUG VSC com.netapp.aegis.discovery.StorageDiscoveryManager [JobId:<JOB>] Retrieving Datastore by moref: Datastore:datastore-<NUM> DEBUG VSC com.netapp.aegis.discovery.StorageDiscoveryManager [JobId:<JOB>] Did not find the Datastore by Moref: Datastore:datastore-<NUM>, returning null

选择控制阀无法通过MOB参考查询找到它：

DEBUG VSC com.netapp.aegis.model.DatastoreStorageDetailsCache JobId + <JOB> count reduced to 0, removing from cache ERROR VSC com.netapp.aegis.sms.provider.DiscoverResourcesManager [JobId:<JOB>] Storage discovery failed, received error during operation: java.lang.NullPointerException.

VMware vCenter UI中显示错误消息

Run Resource Group operation failed for Resource Group AllAFFDatastores. (Error: Unable to discover resources on SCV: Storage discovery failed, received error during operation: java.lang.NullPointerException. Please refer to operation logs for more details.)

有关详细信息、请参见操作日志。
