This simple article provides the steps necessary to password reset a Sun StorEdge T3 array.

  1. Stop all the I/O to the host
  2. Connect a console cable from the master unit to a video terminal and power off all units (both trays in a partner group).
  3. Power up the master unit (leave alternate master off) and interrupt the boot process by hitting RETURN when you see the following message: 
    hit the RETURN key within X seconds to cancel...
    NOTE: If you leave the alternate master on, the T3 Operating System (OS) will continue to boot. Eventually, the OS will assume there is a problem with the master (that we interrupted), disable it, and make itself the master.
  4. At the T300-EP prompt, use the set passwd command to view (and memorize...) the password.
  5. Type reset to reboot, and immediately power on the alternate master (if present).
  6. If you choose, you can change the password after it boots with the passwd command.
