Import/Export Element Descriptor Definitions:
Element Address This field contains the element address of the import/export element reported.
OIR Operator Intervention Required bit
■ 0 = No operator intervention required to make the CAP accessible
■ 1 = Operator intervention required to make the CAP accessible
CMC This bit is set to zero to indicate the import/export element is a CAP.
A CMC bit of zero indicates that exports are to the operator’s domain and
imports are from the operator’s domain.
■ Media shall not leave the domain of the media changer when prevented by
the PREVENT ALLOW MEDIA REMOVAL command (see SPC).
InEnab This bit indicates the import/export element supports the movement of
cartridge tapes into the library.
The library returns a value of 1.
ExEnab This bit indicates that the import/export element supports the movement of
cartridge tapes out of the library.
The library returns a value of 1.
Access This bit indicates whether access is allowed to the CAP element by the hand.
■ 0 = The CAP is open and cannot be accessed by the hand. Or the magazine
at the requested Element Address has been removed. Thus the Full and
Primary Volume Tag information cannot be determined, and should be
ignored. More information about this condition is available through the
Additional Sense Code and Additional Sense Code Qualifier fields.
■ 1 = The CAP is closed and accessible.
Except This bit indicates the operational state of the import/export element:
■ 0 = The import/export element is in the normal state.
■ 1 = The import/export element is in an abnormal state, and the Additional
Sense Code and the Additional Sense Code Qualifier fields contain information
regarding the abnormal state. Other fields in this descriptor might be invalid,
and should be ignored.
ImpExp This bit indicates how the cartridge tape was placed in the element:

operator as part of an import operation.

■ 0 = The import/export element does not contain a cartridge tape.
■ 1 = The import/export element does contain a cartridge tape.
