Hello RZNelipak, First off what is the current version of firmware on your MD3200i? The reason that I ask this is “The password reset switch is not available if your system was shipped after September, 2015. The password reset switch functionality was disabled starting from controller firmware 08.20.09.60 and later versions.” Now when u use the password reset button it just rests the password & leaves all other configuration in place. Please let us know if you have any other questions.
Hello, I need to reset admin password on MD3200i. I know that I have two options to do this: 1. Serial Cable, 2. Reset button on RAID Controller. I don't have any PC with serial port so I need to go with option 2. My questions are: If I have two RAID controllers do I need to use reset button on both of them? Does this reset button do only password reset without touch any other configuration? I'm asking because it is a live data storage and I don't want to lose any configuration. Thank you.
