Another kind of late summary...  The consensus was that the bus 
numbers may change but a WWID is constructed from the device number etc 
so device names will not change.  We ended up not doing that after all 
so I cannot validate this.  But it's good to know next time we have to 
do it...  Thanks to all who responded.

Original post...
We're running Tru64 5.1a on a ES40 w/ several local SCSI adapters 
(KZPAC, KZPSAs, QLOGIC (diff)).  There are SAN disks and tapes attached 
to bus 4 and 6.  If I pull an unused adapter (bus 3) that is unused 
(never had devices attached under 5.1a) will the device mapping get all 
screwed up (bus 4 becomes 3, 5 becomes 4, etc).  I know this would 
happen in 4.x.  I think SAN devices will not be affected (have unique 
WWID).  
What about non SAN SCSI devices on other local SCSI buses higher than 3? 
 Will the cdrom0 (BTL 8-0-0) still map to 8-0-0 and the one and only 
CDROM be mapped to cdrom1 on 7-0-0?  Or can it somehow tell that bus 7 
is the same adapter as previous bus 8 and have cdrom0 still work?
