HP LTO 4 SAS, LTO 4 FC, LTO 4 SCSI manual page, Action, Console Message

Code	Sense Key	Interpretation
7h	DATA PROTECTION	This is an error if the I/O operation is attempting to access the
		media in some manner and failing because data on the media may
		not be accessed at this time (for example, because the tape is
		write-protected; or the drive is unable to decrypt data because the
		key is incorrect).
		For additional sense codes, see “7h—DATA PROTECTION” on
		page 72.
		Also see the Media Write pre-execution check.
	Action:	Depends on the operating system. If this sense key occurs with other
		than an additional sense code of 2700h, the software should log
		the error, terminate the I/O, and then send an error (operating
		system specific) to the calling application. Data on the tape will not
		have been altered.
	Console Message:	Media write-protected or encrypted
8h	BLANK CHECK	An attempt was made to read unwritten media. Recovery from this
		sense key depends on the operating system. It may be regarded as
		an error because more data was expected by the host, or it may be
		an expected condition.
		For additional sense codes, see “8h—BLANK CHECK” on
		page 74.
	Console Message:	End-of-Data encountered
Bh	ABORTED	The drive has terminated the command. This could be caused by a
	COMMAND	problem related to the SCSI bus or Fibre Channel link. For example,
		it is reported if a target or LUN receives a second command from
		the same host before the previous command from that host has
		completed.
		For additional sense codes, see “Bh—ABORTED COMMAND” on
		page 75.
	Action:	Recovery depends on the additional sense code and the operating
		system. In some cases, the host may want to retry the current I/O. If
		the additional sense code is 4E00h (overlapped commands
		attempted), the host may not want to retry the current I/O because
		the previous I/O will not have been completed.
	Console Message:	SCSI protocol problem
