Instructions

The only prerequisite is that the desired user ID is created and present on the Linux operating system prior to performing these instructions.
 

  1. Stop the DPA Agent using the dpa stop command
    Example:  /opt/emc/dpa/agent/etc/dpa stop
     
  2. Edit the dpa.config file
    Change the DPAUSERID value from either blank or root to the user ID desired. (example my_user)

    [root@agent_server01 ~]# cd /opt/emc/dpa/agent/etc
    [root@agent_server01 etc]# vi dpa.config

    Go to this line

    # Custom user setting
    DPAUSERID=

    Change the blank to the desired user ID. If there is already a user ID listed (example root) then change it to the new user ID.

    # Custom user setting
    DPAUSERID=my_user

    Save the file.
     
  3. Modify the owner and group for the DPA agent directory and all contents underneath 
    The user ID should be the same one defined in the dpa.config file in the previous step. The group ID can be set as desired.

    Run the following command

    chown --dereference -LR my_user:my_user /opt/emc/dpa/agent
     
  4. Start the DPA Agent using the dpa start command
    Example:   /opt/emc/dpa/agent/etc/dpa start
