Note: You do not have to record definitions for IBM 3494, 3570, 3575, LTO, and 3592-type devices. These devices use IBM-supplied drivers, not the Tivoli Storage Manager device drivers and will not be affected by the upgrade. 22.5.2 Windows 2003 Storage Agent migration The upgrade procedure is the same as an AIX Storage Agent migration. You may directly install the desired version over a previous one. Ensure that all of your Storage Agent services are stopped before you attempt to begin the migration. Also note that if you use Tivoli Storage Manager Device drivers for your SAN tape devices, the installation wizard will ask you to restart the machine at the end of the migration procedure. When rebooted, your Storage Agent service should be up and running. 22.6 Library migration If you are introducing new tape technology into your environment, you will want to effectively migrate your data from the old library to the new one, with minimal disruption. Or you may want to migrate data from one storage pool, whose data is stored on old generation tapes to the new storage pool defined on the new generation. Since storage pool hierarchy is fundamental to Tivoli Storage Manager, incorporating new storage technologies is an easy task. Essentially, the solution is built on two concepts: Each storage pool must have a device class. Each storage pool's data may migrate to another storage pool. Therefore, if you want to migrate data between libraries, do not think on the library level. Rather, consider that your library consists of one or more storage pools using one or more device classes. Hence, data can be migrated from one library to another by setting up chains of storage pools, where on one side are storage pools in the library that are to be migrated and on the other side are storage pools data are migrated to. Consider the following scenario: You have two libraries, LIB_A with LTO1 tape drives and a new library, LIB_B with LTO3 drives. In library LIB_A, you have two storage pools called archive_tape and backup_tape. In library LIB_B you have other storage pools called archiveLTO3 and backupLTO3. Chapter 22.
