WHAT THE AUTOLOADER RETURNS
LCD Security Valid – Byte 02, Bit 7
This bit indicates whether a change to LCD security is being requested. When
LCD security is enabled, access to certain LCD menu options is prevented. The
settings for this bit are as follows:
0 – LCD security is not being changed. The value of the LCD Security bit
(byte 02, bit 6) should be ignored.
1 – LCD security is being changed according to the value of the LCD Security
bit (byte 02, bit 6).
LCD Security – Byte 02, Bit 6
When the LCD Security Valid bit (byte 02, bit 7) is 1, the LCD Security bit
enables or disables LCD security. The settings for this bit are as follows:
0 – Disable LCD security (factory default)
1 – Enable LCD security
When LCD security is enabled, access to the following LCD activities is
prevented:
 Changing the cartridge loader control mode
 Changing SCSI IDs
 Changing SCSI parity checking
 Changing the emulation mode
 Changing the Ethernet configuration options
 Performing operator panel diagnostics or demo routines
 Using the options for cleaning the tape drive
A user trying to access the operator panel menu options for these activities
receives an error message.
Note: You can also enable LCD security from the operator panel using a
password. (Refer to the Magnum 1x7 LTO Autoloader Product Manual for
information.) Whichever method you use to enable LCD security (operator
panel or MODE SELECT), you must use the same method to disable LCD
security. That is, if you enable LCD security through the operator panel,
you must disable it through the operator panel. Similarly, if you enable
LCD security using a MODE SELECT command, you must disable it with
MODE SELECT.
