Abstract:
1. A method operable in a controlling server for transferring a media loaded in a drive from a first host to a second host, wherein the first host comprises a non-persistent reservation of the drive, the method comprising: sending a logical unload command instructing the first host to logically unload the media and release the non-persistent reservation; determining if the second host will establish a non-persistent reservation or persistent reservation of the drive; sending a logical load command instructing the second host to logically load the media, wherein the media is transferred from the first host to the second host without physically unloading or loading the media; and generating a key for use by the second host in establishing the persistent reservation in the event it is determined that the second host will establish the persistent reservation of the drive, wherein the key comprises an allocation index associated with a drive/media coupling.
