Read Element Status
194 SL500: Interface Reference Manual • July 2008 Revision: F • 96122
ED
■ 0 = The element is enabled (for example a magazine or drive has been
installed or has been logically enabled)
■ 1 = The element is disabled
Medium Type This field provides the type of medium currently present in the element as
determined by the medium changer.
The library returns the following values:
■ 0h = Unspecified - the medium changer cannot determine the medium type.
■ 1h = Data Medium
■ 2h = Cleaning Medium
Source Storage Element
Address
This field is valid only if the SValid bit is 1. It contains the address of the last
element from which the data cartridge was moved.
Primary Volume Tag
Information
When the PVolTag bit is set to 1, the library returns Volume Tag Information.
When PVolTag is set to 0, this field is omitted, and the reserved fields below it
are moved up.
The library Volume Tag Information includes 6 bytes of left-justified ASCII
data which represents volume/serial number data read from the cartridge
tape. The field is padded to 32 bytes with 26 ASCII spaces. If the label on the
cartridge tape is not readable, these 32 bytes will be set to 0.
The last four bytes of the Volume Tag Information consist of two reserved
bytes and two-volume sequence bytes. The library does not support sequence
numbers. These four bytes are set to 0.
Code Set This field specifies the code set used for the identifier field and is set to 0 (not
supported) for the Import/Export Element Descriptor
0h = Reserved
Identifier Type The Identifier Type field indicates the format and assignment authority for the
identifier and is set to 0 (not supported) for the Import/Export Element
Descriptor:
0h = Vendor Specific
Identifier Length This field indicates the length of the Identifier field and is set to 0 (not
supported) for the Import/Export Element Descriptor.
Note: That the combined length of the identifier field and the Identifier Pad is
32 bytes.
Media Domain The Media Domain field along with the Media Type field provides a hierarchy
of information that indicates the type of media in the element:
■ 01h or 53h = The element contains a DLT form factor cartridge.
■ 43h = The element contains an LTO (or future) cleaning form factor
cartridge (43h is ‘C’).
■ 4Ch = The element contains an LTO form factor cartridge (4Ch is ‘L’).
■ FFh = The media domain cannot be determined.
This field is not valid if the Full bit is not set.
