Issue

After both MetroCluster sites fail at the same time, then only the secondary site is brought back online and a forced Switchover is performed, Oracle backups start failing with the following errors seen:

SnapCenter UI:

Running the ONTAP CLi command "File-Directory show" for the affected volumes returns the following error:

(vserver security file-directory show)

Error: show failed: The specified path "<Volume_Path>" cannot be used. Reason: No such file or directory.

When viewing the affected volumes in ONTAP System Manager, no files or directories are displayed, and the following error is displayed:

No such file or directory
