When using FSA to archive data from NetApp Filers running ONTAP 8.0.x, the placeholders become corrupt and cannot be used to retrieve the archived data.
The archived items can be retrieved successfully from ArchiveExplorer as the files are archived correctly in their original state.
EV 8.0 SP4 and previous versions, while archiving from NetApp Filers running ONTAP 8.0.x, would be affected by this issue.
The issue occurs at the stage where the archived item is post-processed and converted to a placeholder. The FSA Task sends instructions to add a hidden ReparsePoint stream to the file, which is deleted by ONTAP due to a change introduced in ONTAP 8.0. When the ReparsePoint stream is deleted the placeholder becomes corrupt.
Enabling Dtrace.exe shows following lines of trace highlighting the issue:
(EvNetAppPHSvr) <8084> EV:H Failed to read the associated Enterprise Vault XML stream, ErrorCode: 2, File: \\?\UNC\FileServerName.DomainName.local\ONTAP_ADMIN$\vol\vol1\Test\FileName.log:veritas.com-80D1BEC9-74E5-4a8c-B96C-B808945AC1BF
(EvNetAppPHSvr) <8084> EV:L WorkItem::IsAPlaceholder (Exit) |The system cannot find the file specified. [0x80070002] |
(EvNetAppPHSvr) <8084> EV:M File 'FileServerName.DomainName.local\ONTAP_ADMIN$\vol\vol1\Test\FileName.log' is not an Enterprise Vault placeholder and will be ignored

Due to the changes introduced in ONTAP 8.0, some methods used by EV to convert the archived file to a placeholder were modified to allow the correct creation of the ReparsePoint stream. These changes were introduced in EV 8.0 SP5 and are included in future builds and versions.
Recall fails for files archived on OnTap 8.0
