Hardware Detection of Errors
The drive contains sensors and circuits to detect errors. A temperature sensor monitors the
temperature of the drive electronics. Voltage sensors detect when the power supply is out of
tolerance. Other errors, such as tape velocity checks, read/write data integrity checks, and
servo checks are performed using circuitry and sensors.
Error Codes Table
The following table details the single-character error codes:
Media error
Fenced
Fenced
Fenced
Failure occurs which cause the drive
to make the volume read-only.
Write Protect
Fenced
Will not write.
Diagnostic Failure

If data path diagnostic fails, medium
access commands are fenced.

1
Cooling Problem
Drive detected an over-temperature condition. Error condition
clears when drive is powered off.
2
Power Problem
Drive detected that the externally supplied power is outside of
specified voltage limits. Error condition clears when drive is
powered off.
3
Microcode Problem
Drive determined that a microcode error has occurred. Drive
dump is required prior to drive being powered off.
4
Microcode or Drive
Problem
Drive determined that a drive hardware or microcode failure has
occurred. Drive dump is required prior to drive being powered
off.
5
Drive Error
Drive determined that a drive hardware failure has occurred.
Drive replacement is required.
6
Drive or Media Error
Drive determined that an error occurred, but cannot isolate it to
faulty hardware or media. Error condition clears when cartridge
is unloaded.
7
Media Error
Drive determined that an error occurred because of faulty
media. Drive dump is required prior to unloading tape in the
drive.
8
SCSI Bus Interface or Fibre
Channel Error
Drive determined that a primary port interface error or Fibre
Channel failure
has occurred. The error condition clears after 10
seconds if the error
condition does not reoccur.
9
RS-422 Error
Drive determined that an interface or library interface failure has
occurred.
The error condition clears after 10 seconds if the error
condition does not
reoccur.
