Starting dsmmigfs.................................. Activating failover operations on the node. REPLACE_LIBRARY mode completed . Note:  In releases before IBM Spectrum Archive EE version 1.2.6, the serial number of a  library was used as the library ID. Beginning with version 1.2.6, the library ID can have a  unique value other than the serial number. A UUID is assigned as the library ID in libraries  that are configured with version 1.2.6 and subsequent releases.  With the separation of the library ID from the library serial number, IBM Spectrum Archive  EE can replace a library by changing the library serial number that is associated with the  library ID. The configuration of the cartridges, and pools, and drives in the old library is  transferred to the new library. Use this procedure to logically and physically move a tape pool from one library (the source)  to another library (the destination), within an IBM Spectrum Archive EE cluster. During the  procedure, the tape pool that is being moved is disabled. However, during most of the  procedure, the IBM Spectrum Archive EE system remains online, and other tape pools  remain available for operations. Note:  Pool relocation will fail if any files are migrated to pools from IBM Spectrum Archive  EE v1.1. To determine if any pools have files from v1.1, run the following command: ltfsee_count_v11_files -p <pool_name> -l <library_name> Pool relocation only works in a multi-library IBM Spectrum Archive EE cluster. Therefore, if  you have a single-library environment and want to move a pool, you first need to have a  second IBM Spectrum Archive EE node added to the cluster and an identical media type  secondary tape library attached. For the pool replacement procedure the following assumptions are made: 8. Verify library serial change by running the  ltfsee_config -m LIST_LIBRARIES. 9. Start IBM Spectrum Archive EE by using the  ltfsee start  command. 10.If you are using new drives in the new library, configure the drives with the  ltfsee drive  add  command. See “The ltfsee drive command” on page 302 for more information about  the command. GLYPH<SM590000> IBM Spectrum Archive EE is configured as multi-library configuration. GLYPH<SM590000> A pool is selected to move from one library (called the  source library ) to another library  (called the  destination library ). GLYPH<SM590000> All physical tape cartridges in the selected pool are moved to the destination library  manually. 1. Get the pool information that is being relocated by running the  ltfsee info pools command. 2.
