Password Reset Issues on Powervault MD3820f
Hey everyone, we recently moved our entire office to a new location. In this process we also had to shutdown our whole server infrastructure of which we knew would never ever come back up the way it had run before. Now we are facing a rather critical issue for our infrastructure. Our Powervault has an password configured, that seems to be different from the default one. (Althought i found a bunch of default passwords on google) I read the documentation and we actually have firmware version 08.20.09.60 in which the password reset was disabled. On top of that, one of our RAID-Controllers died (Boot-Loop, broken battery), which is another problem. Is there any way to reset the password or even factory reset the Powervault? We do not need any configuration or data back from it. Thanks in advance, kedakai

Hi Sam,
thanks for the quick reply.
Unfortunately, we don't seem to have the cable.
Is there any way we could get a cable that is compatible?
Kind Regards,
Kedakai

Hello Kedakai,
Do you have the Serial cable that came with your MD3800f? If you do have the cable, then you can reset the password on your MD3800i. You will need to start Hyperterminal/Tera Term and configure the serial connection settings with the following parameters:
Baud rate: 115200
Data bits: 8
Parity bit: None
Stop bit: 1
Flow control: None
Once you are connected you will need to hit Ctrl S and the password is supportDell. Once you are logged in you will be brought to a Prompt with 4 choices. Once there you can select Administrator password reset. Now you will need to do the password reset on each controller using the serial cable.
Please let us know if you have any other questions.

Hello Kedakai,
Here is the Dell part# VPNP6 for the serial/ password reset cable. You can find them sold by 3rd party vendors as well as Dell. It is good to have the serial cable as if you have any issue with your controllers we can use the serial cable to capture the bootup of the controller. If you still have an active warranty on your MD3820f then we can send you a replacement cable. if you don't then you will need to purchase one.
Please let us know if you have any other questions.

Did every thing as suggested but does not go past the part where I press CAPS S.
Just goes to next line and it stays there...
Any suggestions?

Hi, although the below document doesn't mention that resetting the admin password on the Dell PowerVault MD38xx usually requires rebooting the controller. I always recommend it's a good practice to perform such operations during a downtime to avoid any potential disruptions. Because yes the process does not affect the data on the storage array, but it may cause a temporary loss of connectivity to the hosts. There is such a possibility.
Quoted from page 13 Dell EMC PowerVault MD3800f and MD3820f Storage Arrays Owner's Manual "System Password Reset
The storage array password can be reset if it is forgotten. To reset the password, push and hold down the password reset switch for at
least 5 seconds. The password is deleted.
The RAID controller module allows you to change the password.
NOTE: The reset switch can be accessed by using a small object such as the tip of a pen.
NOTE: 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."
Hope that helps!

Yes, you can reset the lost admin password from the serial terminal. When you select “Reset Storage Array Administrator”, it will reset the admin password. Here are the steps:
Ctrl+S
and okay I can't share the password directly but you can try your mentioned one. (you can check this thread MD3000i Password Reset | DELL Technologies)Reset Storage Array Administrator
.This will reset the admin password. Remember, don't forget to saving a backup of your important data is a smart thing to do.

@Dell-ErmanO
Dear Erman
Can this cause data loss if I initialize the password for the admin user?
thanks

You can do it on both controllers individually..
