Tape Eject command using RSM eject

In my backup scripts for Windows 2003 server we use rsm eject /LF"Library_id"

/Astart and it ejects the tapoe all the time.

When I send the same in Windows XP it says Additional arguments required. I

have no idea what additional arguments are required. It is an HP USB DAT 72

Tape Drive, and it works perfectly on a Windows 2003 server, but not on

Windows XP. I even tried the Guid and changing the command to /LG"GUID" but

it still says additional arguments required.

Any ideas or suggestions would be greatly appreciated.

Cheers
