Before you use the command for adding it to a pool and use the  -F  format option, you must  resolve and clean the relationships from the old files on the tape cartridge to your IBM  Spectrum Archive EE environment. You can do this task by running the  ltfsee reconcile -t  command, first against the specific tape cartridge, as shown in the following example and in  Example 8-20: In some scenarios, you might want to reuse tape cartridges for your IBM Spectrum Archive  EE setup, which were used before as non-LTFS formatted media in another server setup  behind your tape library (such as backup tape cartridges from a Tivoli Storage Manager  Server or an IBM Spectrum Protect environment). Although these tape cartridges still might contain data from the previous usage, they can be  used within IBM Spectrum Archive EE the same way as new, unused tape cartridges. For  more information about how to add new tape cartridge media to an IBM Spectrum Archive EE  tape cartridge pool, see 7.7.1, “Adding tape cartridges” on page 147. This section describes preferred practices to consider when you want to move a tape  cartridge between tape cartridge pools. This information also relates to the function that is  described in 7.7.2, “Moving tape cartridges” on page 149. 8.19 Moving tape cartridges between pools 8.18 Reusing non-LTFS tape cartridges ltfsee reconcile -t <tapeID> ltfsee pool add -p myfirstpool <tapeID> -F [root@ltfs97 ~]#  ltfsee reconcile -t 058AGWL5 -p myfirstpool GLESS016I(00109): Reconciliation requested GLESS049I(00610): Tapes to reconcile: 058AGWL5 GLESS050I(00619): GPFS filesystems involved: /ibm/glues GLESS053I(00647): Number of pending migrations: 0 GLESS054I(00651): Creating GPFS snapshots: GLESS055I(00656): Creating GPFS snapshot for /ibm/glues ( /dev/gpfs ) GLESS056I(00724): Scanning GPFS snapshots: GLESS057I(00728): Scanning GPFS snapshot of /ibm/glues ( /dev/gpfs ) GLESS058I(00738): Removing GPFS snapshots: GLESS059I(00742): Removing GPFS snapshot of /ibm/glues ( /dev/gpfs ) GLESS060I(00760): Processing scan results: GLESS061I(00764): Processing scan results for /ibm/glues ( /dev/gpfs ) GLESS063I(00789): Reconciling the tapes: GLESS001I(00815): Reconciling tape 058AGWL5 has been requested GLESS002I(00835): Reconciling tape 058AGWL5 complete GLESL172I(02984): Synchronizing LTFS EE tapes information [root@ltfs97 ~]#  ltfsee pool add -p myfirstpool 058AGWL5 -F Tape 058AGWL5 successfully formatted.
