Hello, please have a look, this may help:

So, I wonder if the procedure posted here is half baked and the link to the PDF procedure is no longer available...

This is what I did to reset the "Admin" password on a SC9000:

1. format a usb drive as FAT

2. create the unlock.phy file on the USB drive: unlock Admin

3. On the controller iDRAC open the console

4. Insert the USB drive on the "NON" leader controller

5. Wait for the recognition status to complete - DO NOT HIT "ENTER" 

6. *Important, simply type: Admin and hit enter, type mmm as password

7. If you did it correctly, a prompt will appear - next steps at your own risk

8. Type: mc user user show

9. Identify the account ID, typically 1

10. Type: shellaccess developer

11. Type: mc user user passrst 1

12. At this point the password has been reset to: mmm

13. Log into the controller you inserted the USB drive using the default credentials: Admin / mmm

14. Change the "Admin" password

15. Reboot the "leader" controller

16. After Controller comes up, log into the cluster management IP with the password you just setup

17. You are all done.

Hope this may help some one, I had to reset the Admin account of our SC9000 because who knows why, all the accounts got locked, and after a few tries, I figured out that the USB needs to go on the non leader controller and you dont have to hit enter after the USB drive is recognized, otherwise the login prompt will appear and the recovery process will fail.

@lcorona​ Thank you for posting this! That is a great find. I figured it was something simple that was just not written into the password reset document. 

KUDOS man. 

Create a text file containing the following line of text:
unlock Admin (It's a little unclear what to add next)

where   is typically the Admin username. The Admin account is always on the system and it 
has the required Administrator privileges to reset passwords.

2 Save the file and name it:
unlock.phy

Hello,

I can not reset the "Admin" password of sc4020

I followed the following steps but I could not reset it

Tech Tip: Recovering a Locked Administrator Account in
Storage Center OS v6.5
If all accounts are inaccessible because they have been disabled or locked‐out, use this procedure to re‐
establish a local Administrator account and reset passwords.
Prerequisites
This procedure requires a USB device that contains a partition table with one partition formatted with an 
MSDOS/FAT32 filesystem. USB devices vary by vendor as to whether they are formatted with or without 
partitions. Use Windows disk management or other third‐party tools to create a partition if the USB device 
does not have an MSDOS/FAT32 partition.
Steps
1 Create a text file containing the following line of text:
unlock 
where   is typically the Admin username. The Admin account is always on the system and it 
has the required Administrator privileges to reset passwords.
2 Save the file and name it:
unlock.phy
3 Copy the file to a MSDOS/FAT32 formatted USB drive.
Note: Portable Volume  is unavailable during the recovery process.
4 Insert the USB drive into a port on the lead controller. When the media is recognized, System Manager 
allows the specified account to log on.
5 Log on to System Manager using the account specified on the USB drive. The password cannot be blank, 
but any text entered will be ignored.
6 Unlock locked accounts.
7 Reset passwords on accounts.
8 Remove the USB drive from the port.

Can you help me to fix this issue?

Thanks

The procedure from above is 100% correct and works for a SC4020.  What i have made wrong in the past.

1. Misspelled the hard coded administrator Account named "Admin" (not "admin" or "aDMIN")
2. Not used the leading controller (its a 50/50 chance)
3. Windows OS tricked me and create a unlock.phy.txt rather than the unlock.phy
4. Older and smaller USB sticks works better that a rescent 128GB one

It can be took a few minutes until the system recognize the USB stick. I always work over the Serial rather than the DSM GUI for these steps because the command line gives better feedback.

The USB stick with the unlock command enable the use of every password except a empy "" one. So i always use "mmm" which is also the default password for a unconfigured SC.

Regards,
Joerg

I need help with this as well. Were you able to solve this issue? Also, i am using Admin/mmm to login.

For me it always works.

USB FAT format worked but FAT32 did not work for what ever reason.

Hello b.chiam,

If the administrative user name and password have not been changed, use the defaults:

Default user name is admin.

Default password is admin (password is case sensitive).

If the password is lost, the administrative password can be reset through physical access using a special procedure only available by contacting Dell Storage Support.
