It seems that including the boot disk in a RAID5 device isn't possible with
DiskSuite, and even if it were the performance hit would be severe because
of the large amount of I/O the boot disk incurs.
The best suggestion was from MARC.NEWMAN@chase.com who said just mirror the
boot disk, and use RAID5 on any additional disks, and this is probably what
I will do!
Thanks to all those that replied.
