SCSI Interface
3-35
EXB-Exabyte Emulation
When this bit is set to one the library emulates an Exabyte
EXB-120. This setting changes the behavior of the SCSI command
set. The differences in the interface when in Exabyte Emulation
mode are described in “Appendix D,” Exabyte EXB-120 Emulation
Discussion.” When set to zero the library SCSI interface operates in
the default manner as described in this document.
Move Medium (A5h)
The host uses the Move Medium Command to move a tape cartridge
from one element to another within a library. The host specifies the
source element and the destination element in the command block.
The library then moves the tape cartridge contained in the source
element to the empty destination element.
The source and destination elements can be of any type: storage,
medium transport, import/export or data transport element. The valid
combinations of source element type and destination element type are
summarized in the Mode Sense Device Capabilities Parameter Page.
If a valid source element type and destination element type are
specified, the command is valid but the operation may still not be
possible. In this case the library returns Check Condition status and
sets the sense key to Illegal Request.
The Additional Sense Code and Additional Sense Code Qualifier is set
to indicate why the operation cannot be carried out. For example, this
might occur if a source element or destination element is specified
which does not contain a tape cartridge. See Appendix A, Table 1,
“Sense Data Values (Hexadecimal),” for a summary of the conditions,
sense key, and additional sense encoding.
