Can you be more specific ? which Celerra model and OS? What tools? Which permissions ?

We have a Celerra NS120 , version 6.0.41-3, we are using it as our actual storage , but we need to assign permissions in some folders, for example into the Finance Folder only can access the personnel who belongs to Finance security group on Active Directory, on Credit Folder is the same (only Credit Security group can access). But when i try to put the permissions on any folder they are not heritage and what is worst it show me a screen advising me that i do not have privileges to assign permission on the folders, when i always have had the privileges to do it, and the files into this folders got unusable because once i do this, permissions on files and folder disapeared.

you manage permissions on Celerra just like you do on a regular windows file server.

check ownership, check inheritance .nothing special there.

That´s the way i exactly do , but they are not being taken for files and folders....

i already checked those but ask me to change auditing permission but it does not let me change them.

sounds like you may not have sufficient privileges to make any ACL changes. Do you have full rights ?
