ME4024 password reset

Question

Hi everybody, We've purchased a ME4024 system last year. We did the configuration for it, added it to cluster, did a bunch of testing, and went into production with it. A few months down the line, we simply couldn't login to it anymore. It would just say unable to authenticate, please try again. The CLI login would do the same. It's been running just fine, no issues, email notifications also work fine, everything seems to be working fine except the inability to login to it. Last time we logged in successfully we couldn't login to 1 controller, so we went to the other one. The first 2 attempts on the second controller failed, but the third one worked and we got it. Looked at the logs, etc, all good. Next time we tried to login we couldn't login to any controller and we haven't been able to login to Power Vault Manager since. Everybody is saying that we forgot the username and password, but I'm 99.9% sure we didn't, as we did the initial config, weeks of testing, and production launch using these credentials. We are running G280 firmware, so password resets have to be done by Dell. I would like to know if the 'password reset' procedure that dell will perform also erases the disk groups, volumes, data, host mappings, etc. In other words, if we lose the storage configuration and the data. We know the controllers will reboot, and cluster has to be turned off, but we are asking if the configuration and data will still be there after the 'reset password' procedure, and the cluster will be able to operate normally post-procedure.   Thank you to all!

You will need to contact support in order to reset the password. Also, you will need to setup a maintenance window as the controller needs to be rebooted following password reset procedure. You will also need the cable that came with your ME4024 so that you can connect to the serial port on the controller.

As far as your question, the reset process doesn't effect the config or data.

Let me know if this helps.

Thank you for the answer! At this point, the only concern was the config and the data - and you've answered that.

Hello,

For password reset and login assistance, I would recommend contacting phone support, like Chris had mentioned. Regarding your question about the reboot, yes, I do believe you will need to reboot when working with phone support.

As a heads up, this works too for a Dell PowerVault ME5024

When you have SSH access, FOR NOW, I have not been able to get the serial number so it DOES seem you need to be physically on site.

Connect the microUSB cable to your computer to the port labeled CLI. Connect via serial using PuTTY for example.

User: restoredefaults

Password: (serial number of the controller)

Description: It restores the default of what? Because IP is the same, etc. so...not sure what this does.

User: restoreusers

Password: (serial number of the controller)

Description: This deletes the user and password you set. If you have lost the user name and / or password, this is the one you want to run first (or second, if you ran restoredefaults)

User: setup

Password: (blank, no password)

Description: This enables the first run web wizard, which allows you to reestablish a new username and a new password.

Im waiting to see if there is a method to get the serial number ( no, it isnt the one that SSH shows using "show controller") to write it down in documentation.

EDIT: I just noticed something: The "serial number password" on the ME5024 might be the mac so first thing to do is connect thru SSH to the controllers and run "show controllers": This will give you the serial number and the MAC address of each controller. Run this and write it down!

Hello, thank you for sharing this helpful information for accessing and resetting ME5024. It's always useful to have these kinds of tips available for users who may encounter issues with their equipment. Also, I found this article and wanted to add here ME5: How to locate the PowerVault enclosure service tag | Dell UK

Using the Command Line Interface (CLI)
The Service Tag is the seven-digit alphanumeric number that is shown in the output of either of the following commands:

show service-tag-info
show enclosures

Open an SSH session to either controllers' management IP address.

# show service-tag-info

Encl Service Tag

Success: Command completed successfully. (2022-01-21 04:16:23)
