Resetting a node's password

Summary

Occasionally, you need to reset a TSM node's password. Here's how to do it.

Definitions

For this procedure, the following definitions apply:

MY-NODE

The name of the node you wish to update. Please use the fully qualified domain name of the machine in question.

SERVER

The TSM Server instance you are planning to use. For most local admins, the server in question is 'ext'. See the system structure document if you're unsure.

Procedure 1. Resetting a TSM node password. (command line)

  • Register the node

    Having connected to the correct SERVER, use the register node command:

      update node MY-NODE [new password] forcepwreset=yes

    now, perform procedure three to reacquaint client with server.

 

 

Procedure 2. Resetting a TSM node password. (web interface)

  1. Navigate to the node registration screen.

    Having connected to the correct SERVER, locate the register node screen.

    • Operations view

    • Work with client nodes

    • Update a client node

    Select the node you want to change from that list.

  2. Register the node

    Fill out the following fields:

    Password

    Select an initial password for the machine. In most cases this can be a 'changeme' type password, as an encrypted password will be selected by the TSM client on first connection with the server.

    Force password reset ?
    Select 'Yes'

  3. Complete the process.

    Click the 'Finish' button.

    Now, perform procedure three to reacquaint client with server.

Procedure 3: re-introducing the node to the TSM server

  1. Initiate a client session from the target node


    On the client node, query the schedules with which the node is associated 
    dsmc q sched


    this should result in a password transaction, in which you will have to enter the just-set password. You will see, amongst the connection diagnostics, an entry 'Password Updated'.

  2. Check that the password has been cached


    Run the q sched command again:

    dsmc q sched

    which should result in the same output, but not request a password, nor note a password update.
