Hello,   Sounds like you don't have a contact on that array anymore.  You can try to open a T&M case and they can provide you with the response code you will need to reset the password.   You will need to be connected to the serial port of the active controller.  You enter "passwordrecovery" for the login. It will provide the firmware version and a challenge code.  Support will give you the reply.  This will allow  you to login and change the password.   Regards, Don   
Dear Sr.  I have a Dell Equallogic ps 6210 SAN storage and the priviuse system administrator left the company without giving any administrator password, is there a way that we can reset the admin password without affecting the data & the current configuration so that I can access the SAN through browser.
