|If your environment consists of TSM storage pools associated with an ACSLS |library type and a device class containing the GENERICTAPE device type, you |need to consider migration and coexistence issues for existing data. To |take advantage of LAN-free data transfer, the data must be migrated to a |storage pool associated with an EXTERNAL library type and a device class |containing the ECARTRIDGE device type. Data migration is recommended |over coexistence.
