Is there a problem with moving drives from one controller to another that my googlefu is not turning up? I had a system with it''s boot drive attached to a backplane which worked fine. I tried moving that drive to the onboard controller and a few seconds into booting it would just reboot. Performing a fresh install when started connected to the onboard controller would then cause later reboots to function fine. If I reversed the order and moved the drive back to the hotswap backplane, I would have the same reboot problem. Any clues?

If you move a boot drive, you need to update grub. That has nothing to do with ZFS though, that would occur on any OS I''m aware of using grub as a bootloader. --Tim -------------- next part -------------- An HTML attachment was scrubbed...

But in most cases you have to boot from the installation media and "zpool import -f rpool" the pool, with the disk attached at the new physical device path, so that the new physical device path gets recorded in zpool''s on-disk label. -- This message posted from opensolaris.org
