    RAID5 does overcome the limitations of RAID2,3,4 by distributing parity
    information over all disks rather than just one.

    You can allocate 5 log vol / physical vol as long as you don't violate the
    max # of total physical partitions / physical volume rule as applicable in
    your environment.

    To determine which hdisk a given log vol resides:

    lslv -l hd6

    where hd6 is a log vol.
