zfs discuss - Nov 2010 - Moving rpool disks

We need to move the disks comprising our mirrored rpool on a Solaris 10
U9 x86_64 (not SPARC) system.

We''ll be relocating both drives to a different controller in the same
system (should go from c1* to c0*).

We''re curious as to what the best way is to go about this? 
We''d love
to be able to just relocate the disks and update the system BIOS to
boot off the drives in their new location and have everything magically
work.

However, we''re thinking we may need to touch GRUB config files (though
maybe not since "rpool" is referenced in the config file) or at least
re-run grub-install or something to update the MBR on both of these
drives.

Any advice?

Thanks,
Ray

Thanks to those who replied.

This went off pretty well -- after swapping the disks to the other
controller and updating the system BIOS, GRUB came up fine, but the
system wouldn''t boot.

We had to go into failsafe mode (via GRUB) and update the boot archive:

    # update-archive -f -R /a

The system booted up fine after this.

Thanks,
