Davina,

If I am reading you correctly, and I think I am we have the same issue
when we take down our WIndows 2003 server and storage nodes....but
rather than reconfigure the library, there is a much easier fix.  While
it is true that you can not have persistent binding, what you CAN do is
when the Windows 2003 server boots, check your tape drive devices in a
command prompt by running inqure -lc.  This shows you the SCSI devices
addresses for the tape that are currently assigned.  If they are out of
order, you can go into Device Manager and disable your tape devices and
then re-enable them in the correct order by LUN id.  Once you do that,
you can then re-enable Networker and all is well.

If this works for you, I think it beats dumping Windows 2003 for
Solaris hands down.

You're right - it doesn't. Persistent binding only fixes part of the 
mapping - the part which maps WWNN or WWPN to SCSI addresses. The 
mapping of device names to SCSI addresses is done dynamically at boot 
time in Windows. In Solaris this only happens when you run a 
reconfiguration reboot, but in Windows you have no control. It seems 
that no-one involved in the design of Windows ever envisaged using a 
system large enough to run multiple tape drives.

There is no solution other than to use a different operating system.
