One Compaq conttrollers store the config on the drives. You just plug in the newer controller as a drop-in replacement for the old and it recognises all the arrays automatically. Its very nifty. As controllers I love them - they are very easy to use, the management software is good and they are easily available on ebay :-) The only downside is that persuading them to work in non-Compaq machines can be difficult (especially with the later ones). > of the options I'm considering is getting a newer SCSI controller, but I > don't want to have to do a dump | restore on it if I can get around it. You should be able to just plug a 3200 into the same slot, plug in the drives and it will boot. This is what I did. Indeed I took two arraysfrom a pair of SMART 2-SL's and plugged them into a single 3200. If you want to go to a 4200 you need to check that your PCI bus supplies 3.3V as well as 5V. That caught me out and I had to get a newer machine as the server. -pcf.
