		Table C-1. ERPA Codes
ERPA	DESCRIPTION	ERROR
CODE
22	Path Equipment	Drive adapter error occurred.
	Check	Could not recover from a buffer error on the lower interface.
		Could not recover from an error detected during a cartridge index/load cycle on the
		Automatic Cartridge Loader. The cartridge is manually retrievable by the operator.
23	Read Data Check	A permanent read error has occurred.
24	Display Check	A Display command was received while a drive check message is displayed.
25	Write Data Check	Buffered data could not be written on the tape successfully. ERP has tried to erase gaps
		and rewrites but could not complete the write operation.
		A permanent error occurred when trying to write data, an IBG or a tape mark on the
		tape. All attempts to retry the operation have been completed, but unsuccessfully.
26	Attempt to read back-	Host recovery should perform a read forward followed by a backspace block com-
	ward an EDRC packet	mand.
27	Command Reject	An undefined command op code has been issued.
		Control information is improper.
28	Write ID Mark Check	The ID mark could not be written successfully at the BOT. Any data to be written to
		the drive is still in the buffer.
2A	Buffered Log Data	The statistical counters have overflowed and a Request log command should be issued
	Present
2C	Permanent Equip-	Either the control unit cannot recover because an error occurred in the subsystem hard-
	ment Check	ware or microprogram, or the control unit recovery action was unsuccessful.
2D	Data Security Erase	The drive became not ready after the command was issued, or an error occurred while
	Command Failure	the command was processing.
2E	Not Capable (BOT	Either a density mark could not be read correctly or the Block ID read by the control
	error)	unit is invalid (Bit 0 or bits 8-11 are not zero).
		If a density mark could not be read correctly, likely causes are:
		1. a void occurred at BOT, or
		2. a timeout occurred before the density separator was detected.
30	File Protected	A write type operation was attempted on a tape cartridge that is file protected.
31	Tape Void	No patterns or data were found on the tape during a read operation. The tape could be
		positioned after the last data block or tape mark that was written on the tape.
32	Load Assistance	An error caused the drive to lose tape tension.
33	Load/Unload Failure	The cartridge is not inserted or threaded correctly.
34	Manual Unloaded	The drive cannot maintain tape tension and control tape movement during an unload
		operation.
