Riproducete il mount segnalato sull'unità HP Ultrium 5-SCSI con il firmware Z6ED, quindi esaminate la diagnostica MODESENSE (0x5a) del backend sg-ibmtape. Confermate se il messaggio relativo a un campo non valido influisce sul mount, che secondo il log alla fine viene completato correttamente, e documentate il risultato verificato o la modifica specifica per il dispositivo necessaria.
