How to reset password on Storage System Dell SCv3020

Hello!

I tried to reset the password in the following way:
1. I took a 512 MB USB flash drive, formatted it in FAT16, and also tried it with FAT32
2. Created the file unlock.phy using Vim in USB flash drive
3. Added "unlock Admin" to file unlock.phy (first line of file) and save it
4. Inserted into two controllers in turn

But the password was not reset.

What am I doing wrong? Can you recommend anything? I followed all the recommendations from this forum
