Table 22. DDS Tape Module Drive Error Codes
Code Description
06h Capstan motor stalled.
07h During calibration, servo failed to converge to a value within the correct range.
08h Drum is stationary when it should be rotating.
09h Drum phase lock lost during a write. The drive failed to maintain drum phase
relative to tape, so tracks are starting too early or too late.
0Dh During a mode movement, 20s elapsed without reaching target position, or 6.4s
elapsed without any change in rotary encoder state.
15h Servo did not see first command.
16h Drum failed to stop rotating.
17h Reels stuck while drive in process of threading tape.
18h Supply reel stuck during capstan or reel-driven tape motion.
19h Servo ROM checksum failure.
1Ah Too many reel FG pulses detected from supply reel during capstan or reel-driven
tape motion.
1Bh Take-up reel stuck during capstan or reel-driven tape motion.
1Ch Too many reel FG pulses detected from take-up reel during capstan or reel-driven
tape motion.
1Dh Attempt to execute download routine failed because download version does not
correspond to version of servo firmware.
1Eh Communication protocol error indicates servo is “busy” when it should not be.
1Fh Servo cannot respond because it is hung.
20h Filemark encountered during a read, write, or spacing operation.
21h Setmark encountered during a read, write, or spacing operation.
22h Record of unexpected length was read.
23h Format error in the group just read. MEDIUM ERROR.
24h Buffer firmware does not know the logical tape position. MEDIUM ERROR.
25h Parity error on reading data from the buffer. HARDWARE ERROR.
26h Mismatch in number of bytes transferred to and from SCSI, due to firmware or
hardware failure. HARDWARE ERROR.
27h Illegal machine state detected. HARDWARE ERROR.
28h Illegal buffer command received. HARDWARE ERROR.
29h Illegal parameters sent with a valid buffer command. HARDWARE ERROR.
2Ah Space or Locate failed; position specified is in middle of a compressed entity.
2Bh Write Setmarks failed because it would cause the number of setmarks in the
current partition to exceed 65535. No error is logged to EEPROM. ILLEGAL
REQUEST.
