records. An optional count
can be specified. The default is 1.
compress and nocompress:
These subcommands turn the hardware compression

the results. If the drive is not loaded, the current media density is not reported.
display
Message
:
This subcommand displays a message on the display panel of
the tape device. Up to 16 characters can be used for the message. If the message is
longer than eight characters, the display alternates between the first eight
characters and the remainder of the message. For example:
# Display "Test 1" and "Running" messages
IBMtapeutil -f /dev/
IBMtape0 display "Test 1 Running"
encryption:
This subcommand displays the encryption state of the drive.
eof [Count] and weof [Count]:
These subcommands write
count
filemarks. An
optional count can be specified. The default is 1.
erase:
This subcommand erases the tape from the current position through the
physical end of the tape.

count
filemarks. The tape is
positioned on the first block of the next file. An optional count can be specified.
The default is 1.
fsfm [Count]:
This subcommand forward spaces
count
filemarks, then positions
the tape on the beginning of tape (BOT) side of the filemark. The tape is positioned
