gcreate /dev/vgtest /dev/dsk/c16t0d0
Increased the number of physical extents per physical volume to 51199.

Don't need any patch, just increasing the PE size from the default of 4M will work. The max PE size can be 256M. The reason is that the LVM data structures must fit into a single extent on the disk. So if you choose a PE size of 32M then the num of physical extents of size 32M will be 6400 for a total LUN size of 200G.

~hope it helps
