Bear in mind that if you upgrade to Tivoli Storage Manager 5.3.x from any previous release and you have Windows clients that back up their system objects, you should take specific actions to clean up the orphaned system object entries in the database, For details see the IBM Support Web site at: http://www.ibm.com/software/sysmgmt/products/support/IBMTivoliStorageManager.ht ml FILE volumes and paths to FILE devices When the V5.3 server starts, existing FILE volumes in a FILLING state are marked as full. In V5.2.x and earlier servers, the server accepted a PATH definition for a local FILE library and FILE drives, although it was not used in any way. Such definitions are not accepted by a V5.3 server and are rejected. This could be problematic if these definitions are contained in a devconfig file, and must be removed manually. Password length When the server database is upgraded to V5.3.0 or later, the encryption level of stored passwords is converted from DES 56-bit to AES 128-bit. During the conversion, decrypted passwords are checked against the server minimum password length setting. If a password is shorter than the minimum length, an invalid password error message is issued and the database upgrade fails. Passwords shorter than the minimum length can exist if the server's minimum password length setting has been changed. Changing the setting does not affect existing passwords. The new password length is only enforced when passwords are first registered or updated. Any previously created or expired passwords that do not meet the current length requirement are considered invalid during the database upgrade. If there is any possibility that shorter passwords are stored in the server database, use the following upgrade procedure: 1. Temporarily set the minimum password length to zero (0). To change the minimum password length, you can use either the Administration Center or the SET MINPWLENGTH command. 2. Back up the current server database. 3. Install the new version of Tivoli Storage Manager. 4. Reset the minimum password length to the desired value. Transition version of administrative Web interface The Administrative Web interface has been replaced with a completely new Web-based interface called Administration Center. Together with the Integrated Solution Console (ISC) that provides a framework for Administration Center, you Chapter 22. Tivoli Storage Manager upgrade considerations 693
