Position To Element (2Bh) 2
The Position To Element command is used by the host to position the
medium transport element in front of another element within a DX-Series
system. The host specifies the destination element in the command block.
The DX-Series system then moves the transport element in front of the
destination element.
The destination element can be one of these types:
•Storage
• Import/Export
• Data Transfer
If the address is in error, the DX-Series system returns check condition
status and sets the sense key to Illegal Request.
The format of the Position To Element command block is shown
table 38.

Tech Tip: The DX-Series system does not support import/
