Re: [Networker] HBA Persistent Binding & Library Reboot

Thank you! I will try this. 
Is legato support aware of this?
I've opened many support cases but this was never mentioned.

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.
