Cannot change root password in VNX cli ( command line interface) in VNX 5400

Question

As I putty to VNX cli ( believe accessing the VNX 5400 control station), and try to access root account ( # su - ), I am prompted to change password ( 'change your password immediately (password aged) '  ) as follows: Changing password for root,  (current) UNIX password: New UNIX password: Retype new UNIX password: su: incorrect password %%%%%%%%%%%%% For some reason, the new password is not accepted; if I provide an incorrect password for the (current) UNIX password, I am rejected right away. So, I think I have the correct current password; but the new password is  somehow not accepted ( although I have successfully changed the password in the past); Another thing is, in the VNX cli, the root directory ( / ) is 100% used up and out of disk space at the moment ( and I want to address this situation as a root user); I wonder if this situation has something to do the problem of changing the password.  Any help would be appreciated.

Hello fly99h, Have you tried the way in this link to reset your password? https://dell.to/34J8enF

Thank you for the post; I tried a few things, without much success.

Wonder which user has the greatest privilege ( can do/change everything).

According to the documentation, nasadmin is supposed to be a local user; but I have always logged on nasadmin user as global user in GUI; would there be any problem with this?);

From my notes in the past, when we had problem logging into the control station from VNX cli, the problem was supposedly resolved by changing passwords in 3 different places in VNX/Unisphere GUI ( Settings - Global users , Local users for File, and Local users for Block). But, as can be seen, there are currently no users specified in Local users for Block ( Does this make sense?). Also, at one point, I believe we received a new control station as a warranty replacement; does a new control station require special setup ( Are there ways to backup or restore control station settings?)?

And currently, I can do “su - nasadmin” in VNX cli, but it has limited privilege ( cannot act as root); also the password for nasadmin in VNX cli is different from nasadmin password for the GUI login ( wonder how that can be explained). Also wonder, when I attempt to login to GUI, if I can be locked out after so many incorrect passwords.

Which password is the one you want to use? GUI or CLI? Does the root account work from CLI?

Thanks for response. The root account does NOT work from cli ; I want to use root account ( root privilege) in cli so that I could address the issue of VNX cli's root dir ( / ) being out of space ( 100% used up); As I try 'su - ' in cli, it prompts me to change root password right away, but does not accept the new password for some reason ( although I believe I type the current root password correctly, and repeat the new password twice correctly).

Hello fly99h,

You will need to open a support ticket to get the password reset by a support technician. When you are unable to change it via the link I provided earlier, then it needs to be done by a support agent.
