In RHEL5, I developed the udev rules that I posted last night because the tape 
drives were moving around.  It was RHEL6 that started initializing the HBA's in 
random order and actually caused the issue of the scsi host number of the HBA 
that is attached to the control port of the jukebox changing almost every 
reboot.

I also stated in my first message that this jukebox was created (via jbconfig) 
back in 2008 and the NetWorker configuration has come along with me from RHEL4 
and NetWorker 7.3 all the way to RHEL6 and NetWorker 7.6.4 (It's also converted 
from 32-bit to 64-bit OS's in that time).  The reason I can't just delete the 
jukebox and create it again through NMC is because of the multiple days it 
would take to run the inventory of the 1400 tapes in the thing.

I keep trying to get a real test environment with a small jukebox so I can 
experiment with this stuff.  However, so far I have not been able to shake the 
necessary money loose.  Therefore, I am very thankful for the existence of this 
mailinglist and the help that everyone here is giving to all of us.
