DotHill password reset procedure -
In the event the user misplaces the management password for a Titanium (or OEM version of Titanium) and can no longer access the storage system to manage it, there are two ways to access the system to establish management capabilities.
1. The first method to recover from a lost default manage password or a user defined management password is to use an undocumented userid. This userid allows you to create additional management users.
a) The process is to log into the system using the telnet or USB serial interface with the userid of admin and a password of !admin. This will log the user into the system and new users and passwords can be established using the set user command.
b) Once access is obtained, perform a show user command to determine what users exist currently. You will not be able to recover the password for existing users, but you can create new users with the create user command.
c) During user creation, set the management level to manage. Once the user is created you may set any additional user parameters with the set user command.
d) Use the command help set user to determine the options. You may now log out of admin and log into the system with the new user credentials that were just established.
. If the admin option is not successful, the second method is to restore the controllers to factory defaults. This does not affect the vdisks and volumes, including any specific mappings. There is additional information required in this method which is the internal serial number of the controller being accessed.
This serial number can be found in one of two places depending on the OEM supplying the controller. If it is branded as Dot Hill, the serial number is on the part number label that is attached to the faceplate of the controller. If the controller is from another OEM that has a different serial number format, the internal serial number of the controller can be observed from the connector end of the controller (the controller must be removed from the chassis). This procedure does not address the issue of gracefully removing a controller from the chassis. The serial number in either location should have the format similar to DHSISHU-1014D8EA60.
a) Once the serial number is identified, log into the system via the MC serial port with the userid of restoredefaults and the password consisting of 00C0FF followed by the last 6 characters of the internal serial number.
b) In the example above, the password would be 00C0FFD8EA60. This must be entered in capital letters. This method will restore the userids and passwords back to original factory defaults, with the standard management userid of manage and a password of !manage.
c) You can now create additional users if desired with the appropriate parameters. Use the command help set user to determine the options.
d) The factory default settings for the MC were restored but the MC will capture some of those back from the SC. You should review all settings to ensure they are correct.
