Re: physical extent
run "vgdisplay -v" and calculate *your* maximum, like:
PE Size (Mbytes) 16
Total PE 4319
Hope this helps!

Torsten.

Re: physical extent
the number of megabytes in each physical extent, where pe_size is expressed in units of megabytes (MB) in the range 1 to 256. pe_size must be equal to a power of 2 (1, 2, 4, 8, etc.). The default value for pe_size is 4 (four megabytes).
(man vgcreate)
regarding max_pe:
the maximum number of physical extents that can be allocated from any of the physical volumes in the volume group. The default value for max_pe is 1016. However, if the size of any physical volume exceeds 1016 times the pe_size, the default value for max_pe is adjusted to match the physical volume size. The maximum number of physical extents can be a value in the range 1 to 65535.
This gives a maximum of 16TB.
(at least for 11iv3)
Hope this helps!
Regards
Torsten.

Re: physical extent
The man page for vgreate is useful for the options.

Re: physical extent
128Gb for HFS
1Tb for VxFS *if* you have JFS 3.3 and create a version 3 or 4 filesystem. JFS 3.3 is an extra product (but not likely available anymore as HP-UX 11.00 is obsolete). Here are the details:
