Networker will stop library operations, log entry states "library state has changed to from ready to cannot access the hardware". 

No further polling of the library is attempted by the software.  This can leave tapes stranded in drives since the software will not issue a move command to return the tape to source slot.

If multiple initiators can access the hardware (library), the Library can return a 'busy' status to the Networker server, after this Networker won't attempt to communicate with Library any longer .

This is caused due to inability of Legato to share library amongst mutiple initiator . Resolution for this is to limit access of the library to Legato master server only . Reset Library in EMC Networker to recover it from "busy" state.
