SEPTEMBER 2005 MAGNUM 1X7 LTO AUTOLOADER
19-13
WHAT THE AUTOLOADER RETURNS
LUValid – Byte 06, Bit 4
This bit indicates that the Logical Unit Number field (byte 06, bits 2 through 0)
contains valid information as follows:
0 – The Logical Unit Number field is not valid because a tape drive is not
installed at this location.
1 – The Logical Unit Number field is valid because a tape drive is installed at
this location.
Logical Unit Number – Byte 06, Bits 2 through 0
The value reported for this field is 0.
SCSI Bus Address – Byte 07
The value reported for this field is the tape drive’s SCSI ID.
SValid – Byte 09, Bit 7
This bit is set as follows:
0 – The Source Storage Element Address field (bytes 10 and 11) is invalid.
1 – The Source Storage Element Address field (bytes 10 and 11) is valid.
Invert – Byte 09, Bit 6
The autoloader uses single-sided media and does not support inverting of the
media (recording on both sides of the tape). The value reported for this bit is 0.
Source Storage Element Address – Bytes 10 and 11
This field shows the addresses of the last storage element from which the
cartridge was moved.
Primary Volume Tag Information – Bytes 12 through 47
When the PVolTag field (in the Element Status page described in page 19-5) is
set to 1, the Primary Volume Tag Information field contains the volume tag
information of the cartridge in this tape drive. The autoloader supports eight
bytes of volume tag information, so only the first eight bytes reported are
valid.
Note: Although the autoloader cannot scan a cartridge loaded in a tape drive,
bar code label information can be reported if the cartridge was scanned
before it was loaded inside the tape drive. The autoloader obtains this
information from the cartridge inventory. Check to see if the Except field
(byte 02, bit 2) is set to 1. If it is, the label information reported may be
inaccurate because the cartridge inventory is questionable.
