问题描述

在计划备份作业期间,托管在 NetApp 存储上的 CIFS 共享间歇性地在在线和离线状态之间切换。这会导致备份失败,备份应用程序将装载路径报告为不可访问。从 Windows 资源管理器手动访问相同的共享(使用相同的备份用户帐户)通常可以同时工作。

CommVault 错误消息:

Device went offline
FailureReason: Mount path is inaccessible.
Check the following.
a. Is the mount path visible to the operating system on the MediaAgent machine?
b. Is the username/password correctly entered?
c. Does this user have read/write privileges to this mount path?
