Resettings 3ware's 3DM2 Password Revision as of Sunday, 27 December 2015 at 07:27 UTC

All settings are stored in /etc/3dm2/3dm2.conf. The default password
is “3ware”. It is encrypted as twOmwmsK8lKk2 like so:

ROpwd twOmwmsK8lKk2  
ADMINpwd twOmwmsK8lKk2

Once you set a user and admin password, it changes to another value. To
restore the password to “3ware”, first kill all running 3DM2 processes:

sudo pgrep 3dm2 | xargs kill -9

Then edit the file to restore the default values of ROpwd and
ADMINpwd. Now start 3DM2

sudo 3dm2

Bam.
