Table 7. Fault Symptom Codes (FSC) and Error Recovery Procedure (ERP) Numbers (continued)FSC Description ERP Number Cause9E The permanent write error rewrite threshold has beenreached. 1 8,6D = 30%T = 70%9FServo zone read-back-check failure on a write. Theservo zone is a written section on the tape that verifiesthat the tape is correctly aligned with the drive head.8,6D = 30%T = 70%A1 A tape drive head synchronization error occurredduring a WRITE operation. 8,6D = 90%T = 10%A2 An underrun error occurred during a WRITEoperation. 12 D = 100%A3 An Logical Port write buffer CRC error occurred. 12 D = 100%A4 A Physical Port WRITE buffer CRC error occurred. 12 D = 100%A5 Buffer positioning was lost during a WRITE aboutprocess. 12 D = 100%A6 An Logical Port READ buffer CRC error occurred. 12 D = 100%A7 A Physical Port READ buffer CRC error occurred. 12 D = 100%A8 A Physical Port parity error occurred. 12 D = 100%AC A servo software error occurred. 12 D = 100%AD A servo hardware error occurred. 8,6D = 10%T = 90%AE The drive is not tracking correctly. 8,6D = 40%T = 60%AF An PEOT or PEOP was encountered during a motioncommand 2 D = 100%B0 The drive is not tracking — the tape is damaged. 8,6D = 40%T = 60%B3 A LBOT or LBOP WRITE failure occurred 8,6D = 30%T = 70%B4 A LBOT failure occurred. 8,6D = 30%T = 70%B5 The read manager could not read the LBOT or LBOP. 8,6D = 30%T = 70%B6 And End Of Tape (EOT) mark was encountered whenthe buffer was being emptied. 2 IC0 A power-on reset occurred. 3 IC1 The tape may have been changed. 3 IC2 The MODE SELECT parameters have changed. 3 IC3 New microcode was loaded. 3 IC4 The operator requested media removal. 11 IC5 An incompatible media that was inserted was rejected. 14 IC6 The drive is not ready, the cause is not known. 7,3 IAppendix B.
