We recently bought the following server HP ML370R05 E5430 Base EU Svr. We also have a HP Ultrium 448 Internal Tape Drive installed to this server. So far we have been unable to make this tape works. We show on Backup Exec that tape drive is offline. We have tried two different version of Backup Exec (version 9 and version 12.5) same issue was repeated, device was offline and could not be used.
the device manager shouw the tape drive and the SCSI controller without any problem.
