In our case the registry entry
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Tape  does not exist
but, I do see HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Mchgr
with the persistence DWord setting does this make sense???

Fiber channel persistent binding within Windows will never be enough to
cause consistency. Windows has a higher level API called the device plug
and play driver that assigns the names like "\\.\Tape0". The default
Windows settings will cause the behavior you describe. To fix, delete
the jukebox and devices and modify the Windows registry

>From KB 873337 (the hotfix mentioned is in SP1)

http://support.microsoft.com/kb/873337

Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Tape
On the Edit menu, point to New, and then click DWORD Value.
Type Persistence, and then press ENTER.
Right-click the Persistence registry entry, and then click Modify.
Type 1 in the Value data box, and then click OK.
Quit Registry Editor.
Restart the computer.

When you restart instead of "\\.\Tape0" the devices will be named
"\\.\Tape65463" or simular based on their serial numbers.
