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
COMMAND
The drive has terminated the command. This could be caused by a
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
