Veritas.  Unlike DiskSuites, Veritas writes enough meta-data on each
disk under it's control to find them no matter where they end up after a
reconfig reboot.  

Many years ago I had several servers running large, multiple volumes
under DiskSuites and saw Sun's new storage array (the original SSA). 
They demoed it with Veritas to show that you could bring the system
down, swap all the drives around in the SSA, boot -r, and be up and
running all the raid volumes with no hands on the keyboard.  Of course,
the RAID stripes were no longer optimally spread across all controllers
in the SSA, but Veritas sure makes it easy to deal with any
hardware/device changes.

Cheers,
