I do the same thing for AIX. And I use these steps :

   * dsmc query session </dev/null, if ok client is already configured,
     if not
   * dsmc set password <PASSWORD_IN_DB> <NEW_PASSWORD>

Hello tsm world,

     I'm automating the Unix tsm client installations for our operations
staff. I've created a Solaris package to do the trick and all is going good
except for the last part of the package postinstall script I'm writing. You
see I can't seem to automate the: "dsmc  q sess" command. I want the
package postinstall script to enter this command at the end of the script
then when it asks for the user id hit <ENTER> automatically then type in
the password to the node automatically so that it will authenticate into
the tsm server. Since the nodes are all "passwordaccess generate" this
should be the only time they have to do it, but I want the package add
script to do it. Any suggestions on automating the <ENTER> key for the
"enter admin id" prompt, and any suggestions for automating the node
password prompt?:
