TSM Upgrade
Fri, 23 Nov 2007 04:24:36
I'm re-writing this article as initially it said 'If you want to upgrade to 5.5 you need to remove previous versions first. But now it says, you can just run the 5.5 installation and have it automatically upgrade your TSM server. Why the confusion? In the TSM 5.5 guide it states "Tivoli Storage Manager Version 5.5 requires any version of Tivoli Storage Manager earlier than Version 5.5 to be uninstalled before installing Version 5.5." However it also states "You can install Tivoli Storage Manager Version 5.5 over a previous version of Tivoli Storage Manager, upgrading your server." Interesting. After a post on http://adsm.org and a call to IBM I can confirm you may run an in place upgrade. I've taken a couple of pages from the TSM 5.5 installation guide for your review.

Upgrading to Tivoli Storage Manager Version 5.5
You can install Tivoli Storage Manager Version 5.5 over a previous version of Tivoli Storage Manager, upgrading your server. If you are upgrading from Tivoli Storage Manager Express Version 5.3, see "Upgrading from Tivoli Storage Manager Express" on page 1 before installing Tivoli Storage Manager.
Compatibility with other versions of Tivoli Storage Manager Ensure that your Tivoli Storage Manager server and the storage agent can function together by checking compatibility restrictions. To ensure compatibility between the server and the storage agent, check the Tivoli Web site at http://tinyurl.com/3eye6v for maintenance level requirements and to download the latest fix pack level. The Tivoli Storage Manager servers for the AIX, HP-UX, Linux, Sun Solaris, and Windows operating systems support LAN-free data movement.
The Tivoli Storage Manager server and storage agent are not backwards compatible with previous releases of the server and storage agent. If you have implemented library sharing, server-to-server, enterprise configuration, or LAN-free, it is important to note that all Tivoli Storage Manager servers and storage agents must be upgraded to a compatible and supported level of Version 5.3 or later code before invoking any Version 5.3 library sharing, server-to-server, or LAN-free communication. When upgrading multiple servers participating in library sharing to Version 5.5, the servers acting as library manager must be upgraded first to maintain compatibility among the servers acting as library clients or storage agents. When
upgrading multiple servers participating in server-to-server to Version 5.5, all servers must be upgraded at the same time.
As a general rule, Tivoli Storage Manager server will normally support storage agents and library clients at the same version, release, and modification level down to the modification level minus two. When the product release changes, Tivoli Storage Manager will normally support the last two maintenance releases of the previous release. For example, a Tivoli Storage Manager Version 5.5.0 server supports storage agents and library clients at the Version 5.5.0, Version 5.3.4, and Version 5.3.3 levels. An exception to this rule is where a fix or a product enhancement requires concurrent code changes to server, storage agent, and library client. Version 5.5 servers acting as library managers are compatible with Version 5.4 and 5.3 servers acting as a library client. However, Version 5.5 storage agents are incompatible with Version 5.4 and Version 5.3 servers acting as library managers. When upgrading multiple servers participating in library sharing to Version 5.5, the servers acting as library managers must be upgraded first to maintain compatibility among the servers.
Tivoli Storage Manager Version 5.5 requires any version of Tivoli Storage Manager earlier than Version 5.5 to be uninstalled before installing Version 5.5. If you are upgrading to Tivoli Storage Manager Version 5.5, consider doing the following:
Set up a Tivoli Storage Manager Version 5.5 server on a non-production machine. This provides a way to test new function before upgrading your production database.
Perform a full database backup. See the Administrator Guide for details. Also save a copy of the volume history and device configuration files. For additional information, see the BACKUP VOLHISTORY and BACKUP DEVCONFIG commands in the Administrator Reference.
You can use the DSMSERV RESTORE DB utility to restore older versions of Tivoli Storage Manager databases where needed; this utility will perform database restores from earlier releases or versions of the product. If an error is encountered, contact IBM support to diagnose the cause of the restore database failure and resolve it if possible.
Note that the database backup needs to be on a currently supported device, as IBM does not support being able to read from devices that are no longer available. v Add about 25% additional database space. New levels of Tivoli Storage Manager incorporate support for various new functions, which will require additional database space. After the upgrade, when the database space has stabilized, you may be able to reduce the amount of space allocated to the database.
Note: When upgrading to Tivoli Storage Manager Version 5.5, the time necessary to install the package can be considerable, depending on the number of Windows clients registered. The more Windows clients registered, the longer it will take to install the package.
