I suppose you are thinking lvm disk striping.
Have you checked the hp doc (such as http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01916033/c01916033.pdf (BSC link updated by admin))

also many forum threads on the subject.

and many others.

If you are SAN connected, your LUNs are probably stripped across multiple disks.

What is your storage / storage configuration ?

# lvcreate -L 90 -i 2 -I 64 vg_name

you have to have same number of free disks as many you want to strip.
