Hi Justin, ZFS makes use of Device IDs (aka "devids") which are unique to each device, and persistent. Changing the controller should not change the devid. You can examine devids using "prtpicl -v" and searching for the word "devid" > 2) if i create a raidz2 on 3 HDs, do i have any resilience? If any > one of those drives fails, do i loose everything?

Have a look at the ZFS doco (docs.sun.com) and the ZFS Best Practices Guide (www.solarisinternals.com and www.genunix.org). James C.
