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?
