To my knowledge, this statement is incorrect. We don't use persistent 
binding or any other tweaks to run our networker installation, which is 
running on Solaris 10.

First, when a reconfigure is done, the tape devices found are mapped into 
the /dev/rmt device tree. These device files will remain there until 
removed. If you add more tapes or replace a tape drive with one that has a 
different WWNN, it will create a new device file/number for that drive and 
leave the old one untouched.

Furthermore, we have found that if drives are using the same WWNN, SOlaris 
will always map them in the same order for each reconfigure (after erasing 
everything in /dev/rmt). Although, our drives never change WWNN since our 
Spectra T950 gives them this address based on their location in the 
library chassi, even though they are direct fabric attached LTO-4 drives.

Ps. Why did Sony even bother releasing SAIT-2?
Three times the media cost as LTO-4 and not even
half the throughput.. And considering the piss-poor
track record of SAIT-1... :P
