CHAPTER 19—REQUEST VOLUME ELEMENT ADDRESS (B5h)
Element Address – Bytes 00 and 01
This field contains the element address of the storage element (cartridge
storage cell).
Access – Byte 02, Bit 3
This bit indicates whether the cartridge loader can access the cartridge. The
cartridge storage location is always accessible. The valid value for this bit is 1.
Except – Byte 02, Bit 2
The Except (exception) bit indicates the current state of the cartridge cell, as
follows:
0 – The cartridge cell is in a normal state.
1 – The cartridge cell is in an abnormal state and the Additional Sense Code and
the Additional Sense Code Qualifier fields contain information regarding
the abnormal state.
Full – Byte 02, Bit 0
This bit indicates whether the cell contains a cartridge. Since no match could
have been made if there was no cartridge present, the value for this bit is
always 1.
Additional Sense Code (ASC) – Byte 04
If the cell is in an abnormal state, this field contains the value 83h. Refer to
Table 19-2 for the corresponding ASCQ values and a corrective action for each
abnormal state.
Additional Sense Code Qualifier (ASCQ) – Byte 05
The values for this field are listed in Table 19-2, along with the corrective action
to take for each abnormal state.
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 address of the last storage element from which the
cartridge was moved.
