Hi ! I need a way to disable SMBV1 on my vnx unified

Hello,

I am looking to disable SMBV1 on my array, because the vulnerability test ran by our security officer has detected that, SMBV1 is enabled on the box.

My Box is VNX5300, with version,

[nasadmin@PNCPCS1 ~]$ server_version ALL

server_2 : Product: EMC File Server       Version: T7.1.79.8

server_3 : Product: EMC File Server       Version: T7.1.79.8

I have already tried your commands, but no luck,

[nasadmin@PNCPCS1 ~]$ server_param ALL –f cifs –m smb1.disabled -v 1

server_2 :

Error 2100: usage: server_param { | ALL }

   -info

   -facility { | -all }

        { -list

        | -info { [-verbose] | -all }

        }

   -facility -modify -value

server_3 :

Error 2100: usage: server_param { | ALL }

   -info

   -facility { | -all }

        { -list

        | -info { [-verbose] | -all }

        }

   -facility -modify -value

[nasadmin@PNCPCS1 ~]$

Can you pls. advise me here ?
