Restoring Access to a CTPView Server

 

You must use a nonroot password to log in to the CTPView server. If you lose all the nonroot passwords, then you cannot access the CTPView server.

To perform tasks on the server as a root user, you must first log in using an existing nonroot account. You then switch to the root account with the command su - and enter the root password.

This topic describes how to restore access to the CTPView server in any of the following events:

  • You lose the passwords to all nonroot user accounts.

  • You lose the root password.

  • You lose the all nonroot user passwords and the root password.

Before you begin, you must have the GRUB Boot Loader password and physical access to the server with a connected monitor and keyboard.

If you have do not have the GRUB Boot Loader password, you must use the system motherboard jumpers to disable the password protection feature before proceeding. You can find details about how to perform this task on the Dell PowerEdge Documentation CD, which was included with the original packing material for the CTPView server.
