Yes, it is no problem a larger HDD will kick in for a smaller one. Another feature of Perc6 is the CopyBack. Means once a failed HDD has been replaced it will free the kicked in hotspare w/o degrading the RAID.
So you shouldn't have to worry about that.

I'm thinking of setting up the 2x73 drives as RAID 1, and 3 of the 146 GB drives as RAID 5. The remaining 146GB drive as a global hotspare. In this case, if one of the 73GB drives fails, I'm assuming the controller can use the 146GB drive as a hotspare -- but then what would the procedure be to replace the failed 73GB drive with another, rebuild the RAID 1 volume, and then return the 146GB back to global hotspare status? Or would I be better off just replacing the failed 73GB drive with another 146gb, and just set it to hotspare status?
