How to wipe contaminated files from filesystem
I think I know the answer, but let's play anyway ...
Lets say you have a directory of proprietary files that you want wiped from a filesystem.
I mean - OFF - overwrite all blocks associated with the files.
Any wipe tools or methods for Celerra NAS ( 5.6 ) ?
I remember hearing there might be some crude methods at the LUN level - but am looking for something more surgical.
Mount FS with CIFS and use BCWipe from Windows machine ?
Link to any EMC docs ?

Nothing special
But since the Celerra does a direct Block override ( unlike WAFL
) you can use any file based erasure program that doesn't mind network shares
There are several out there from freeware to DoD certified

P.S.: make sure any snapshots are also expired

true
what I meant is either delete offending snapshots (for the whole fs) or wait till they are refreshed before you claim that the erasure is fully done
