WHAT THE LIBRARY RETURNS

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

The values for this bit indicate the following:

Invert – Byte 09, Bit 6

The library uses single-sided media and does not support inverting the media.

The value reported for this bit is 0.

Source Storage Element Address – Bytes 10 and 11

This field shows the address 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 on page 15-5) is

set to 1, the Primary Volume Tag Information field contains the volume tag

(bar code label) information of the element being reported by this element

descriptor. The library supports eight bytes of volume tag information, so only

the first eight bytes reported are valid.

Note: Although the library 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 library 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.

Code Set 1 – Byte 48, Bits 3 through 0

The value returned for this field is 2h, which indicates that the Device

Identifier 1 field (Bytes 52-85) contains ASCII characters. If DVCID is 0, the

value for this field is set to 0.

Identifier Type 1 – Byte 49, Bits 3 through 0

The value returned for this field is 1h, which indicates that the first eight bytes

of the field contain the tape drive’s Vendor Identification as returned in the

tape drive’s Standard Inquiry Data. If DVCID is 0, the value for this field is set

to 0.

The Source Storage Element Address field (bytes 10

and 11) is invalid

The Source Storage Element Address field (bytes 10

and 11) is valid
