Symptoms


The LTO tape drive went offline and because it's path could not be found, its media type changed from "li" to "tp'

The 'samu r' display below shows the failed drive (eq 53) having a 'type' of 'tp' instead of 'li' and with a 'state' of 'off'.  It also reports a 'status' of "media changer reports no access".
