Volume information missing in FPolicy request for NFS

Hi,

I have configured NetApp FPolicy on a NFS volume. The FPolicy server I have developed get requests from NetApp. I am filtering the following operations (NFS_REN, NFS_REN_DIR, NFS_DEL, NFS_DEL_DIR, NFS_SET_ATTR).

I am using Data ONTAP 9.1. In the respose that NetApp sends, there is no information on the volume in which the file is present.

Here is a sample response that I got for Rename of a file:

"...."<?xml.version="1.0"?><Header><NotfType>SCREEN_REQ</NotfType><ContentLen>1135</ContentLen><DataFormat>XML</DataFormat></Header>..

<?xml.version="1.0"?><FscreenReq><ReqId>401673</ReqId><ReqType>NFS_REN</ReqType><NotfInfo><NfsRenReq><CommonInfo><ProtCommonInfo>
<ClientIp>10.1.10.84</ClientIp><GenerationTime>1495492522475821</GenerationTime><UsrIdType>UNIX_ONLY</UsrIdType><UsrContext><UnixUid>502</UnixUid>
</UsrContext><FileOwner><UnixUid>502</UnixUid></FileOwner><AccessPath><Path><PathNameType>WIN_NAME</PathNameType><PathName>\Data\boot.log</PathName>
</Path><Path><PathNameType>UNIX_NAME</PathNameType><PathName>/Data/boot.log</PathName></Path></AccessPath><VolMsid>2155207719</VolMsid>
<FileSize>28028</FileSize><NumHardLnk>1</NumHardLnk><IsOfflineAttr>0</IsOfflineAttr><FileType>FILE</FileType><IsSparse>0</IsSparse><IsDense>0</IsDense>
</ProtCommonInfo><ProtVer><MajorNum>3</MajorNum><MinorNum>0</MinorNum></ProtVer><UserGids>20.702.12.61.79.80.81.98.701.33.100.204.395.398.399.</UserGids>
</CommonInfo><TargetAccessPath><Path><PathNameType>WIN_NAME</PathNameType><PathName>\Data\boot_renamed.log</PathName></Path><Path><PathNameType>UNIX_NAME
</PathNameType><PathName>/Data/boot_renamed.log</PathName></Path></TargetAccessPath></NfsRenReq></NotfInfo></FscreenReq>

Here we can see that the file boot.log got renamed to boot_renamed.log. But how can I find the volume where the file is located? Is there some way to request that information from NetApp's FPolicy engine?

Thanks for your help!

<VolMsid>2155207719</VolMsid>

volmsid is Master data set ID (msid) which is like a unique id for volume a bit like FSid what we have on 7mode system. there're some differences as well.

use the volume show command with msid to find it

thanks
