Dell Networking SmartFabric OS10: Password Recovery

VRMware,

To start, would you confirm what switch you are working on, as well as what version of OS10 you are using?

Also, is the switch up to date?

From the details provided, the things I would look at are

The new password might not have been saved properly. Ensure you use the write memory

command after changing the password to save the configuration.

There might be a step missing or incorrectly followed in the password recovery procedure. Double-check the steps to ensure everything was done correctly.

Different versions of OS10 might have slight variations in the password recovery process. Ensure you are following the procedure specific to your OS10 version.

Let me know what you see and if this helps.

@DELL-Chris H ​ It's a MX9116n with Dell OS 10.5.6.x.x. I followed and double checked the procedure several times. The "write memory" option isn't described in the procedure. Is the "write memory" option available in GRUB mode?

The write memory command is shown in step 5 and also in step 9 on the guide you linked. It is what will save that change nefore the restart, without doing that would cause it to not be saved and reverts back on the restart. 

@DELL-Chris H ​ For security reasons, I have disabled the linuxadmin account. So if I understand the procedure correctly, first I need to reactivate the linuxadmin account and change the linuxadmin password. Then I restart the switch and follow the procedure to reset the administrator password. I will try it tomorrow and update the results here. Thanks so far. 

Using the script named in Step 5 works fine and finally I have succesful changed the password.
