ERROR CODES

This appendix describes the errors reported by the autoloader. The autoloader

uses two methods for reporting error conditions:

 Errors that occur only when the autoloader is being operated from the

operator panel or in Sequential mode, or when the autoloader is performing

diagnostics, only appear on the LCD and are not reported by the REQUEST

SENSE command.

 If the autoloader is operating in Random mode, errors are reported over the

SCSI bus. Some of these errors also appear on the LCD, others do not.

Section A.2 on page A-6 describes errors reported over the SCSI bus are

associated with the sense key data returned by the library in response to a

REQUEST SENSE command (see Chapter 18).

A.1 ERROR MESSAGES DISPLAYED ON THE LCD

This section describes the error messages that can appear on the autoloader’s

operator panel and provides corrective actions. If an LCD error has a Sense

Key value of 4h (Hardware Error) or 5h (Illegal Request) it is also reported over

the SCSI bus in response to a REQUEST SENSE command.

Caution

Most autoloader components can be replaced only by Exabyte-approved service

providers. If you cannot find an obvious cause for the problem, contact your

service provider. Do not attempt to replace any components other than the tape

drive. If you do, you will void your warranty.

! Important

Some corrective actions advise you to reset or power the

autoloader off and back on. To avoid disrupting communication

between the host computer and other devices on the bus, make

sure that there is no activity on the bus before you reset or power

off the autoloader. If you need to power the autoloader off, first

unload the cartridge from the tape drive, if possible, to avoid

possible damage to the cartridge.
