The storage agent referenced is not able to perform LAN-Free data movement operations using this storage pool and device class. The storage agent is back-level and is not able to support LAN-Free operations using this device class.
LAN-Free data movement operations are not performed. The operations are either sent via the LAN or else proxied by the storage agent directly to the server.
In TSM version 5.3, a change was made to the way the FILE and device classes are supported. This change prevents back-level storage agents from being able to use these device classes. The storage agent should be upgraded to the same version and release as the server. Until the storage agent is upgraded, any LAN-Free data movement operations that are attempted will be done using the LAN.
