HP Integrity NonStop H-Series - Manual (Page 68)

Section 4: SCSI Bridge Electronics
Pressing the mode switch at this menu item invokes the drive self-test and offers a series of options from
which you can select. This standalone exerciser can be used to diagnose problems within the tape drive.
Modes of operation include fixed/variable block transfers, spacing, differing densities/compression modes,
and a means to control the running time. Records are written with interspersed filemarks, rewound and
read/verified. This cycle repeats for other densities supported by the tape drive. During the testing process,
you can observe the error rate. If after you use a new tape and clean the heads, a high error rate persists,
you might have a tape drive problem. Other errors might display the KEY/ASC/ASCQ bytes of a Request
Sense command that are described in your tape drive product manual.
