SLAG (Storage Level Access Guard) & ONTAP 9

Just a quick question I hope.  I am migrating an older ONTAP 8.2 (7-mode)  filer.  I believe it had SLAG enabled on a UNIX volume primarily to enable CIFS auditing.

This SLAG setup may have been present when the filer was initially at 7.x levels, but that is a guess and before my time.


I suspect that at ONTAP  9.x  SLAG is not required for auditing.  When I searched the CIFS and NFS Auditing guide for SLAG I found no references to SLAG.


So am I correct in believing that SLAG is nolonger required for UNIX (NFS) auditing because of the nfsv4  acls be available now ? 


I would ideally like to simplify the auditing and remove the SLAG if its not needed for enabling auditing anymore.

Thank you for contacting NetApp communities, yes you are right SLAG is no longer needed NFS auditing.


Please check the documentation for more information :-

Thanks for the response,  it confirms what I thought I was reading in the guides.   I have been unpicking an old filer and trying to

make sense of the configuration.


Just for clarity can you confirm in the new environment ONTAP 9.1 P1  the volume is : /vol/volname  security = UNIX

it is  exposed to clients via NFS exports And CIFS Shares.


So if I add suitable NFSv4 ACL to the volume.  I should get audit events  when the share is access from either

NFS or CIFS protocals.   Is that correct ?
