Symptoms
Avamar SQL 备份可能会失败,并显示类似于以下内容的错误:
avsql Error <40258>: sqlconnectimpl_smo::get_installed_instance_list Microsoft.SqlServer.Management.Smo.SmoException: SQL Server WMI provider is not available on SQLMACHINE. ---> System.Management.ManagementException: Invalid namespace
Cause
备份代理 (avagent) 服务使用 NT 域用户帐户运行,即使该帐户在 SQL Server Management Studio 中分配了 sysadmin 角色也是如此。
默认情况下,avagent 服务使用默认本地 SYSTEM 帐户运行。
Resolution
将 avagent 服务帐户更改回本地 SYSTEM,然后重新启动服务以使更改生效。确保在 SQL Server Management Studio 中为“NT Authority\SYSTEM”帐户分配了 sysadmin 角色。
如果上述解决方法不可行,请向戴尔支持部门提出新的服务请求,并参考此知识库文章。
