San diskinfo size not fully included in pvdisplay - how to LVM it

Hpux Itanium 11.23 is attached to clarion CX4 using dynapath driver.
We have expanded a San disk from 100gig to 133 giga. with diskinfo /dev/rdsk/c8t0d2 we see the capacity is there. Sofar so good. No problems here.
However,
with pvdisplay /dev/dsk/c8t0d2 we see total PE=3124 of 32MB PE-size. Which does not total 133Giga but the original 100Gb.

As far as I know there is not a pvextent command in LVM. How do I tell LVM to use that extra 33Giga capacity.

Ioscan -kfnC disk show good situation
all disks are claimed. Beware !! We did not add disks, only expanded an existing SAN disk.
So ioscan should not show a different picture
(and it doesn't). Hope that is clear.

disk 10 0/3/1/0/4/0.1.5.0.0.0.1 sdisk CLAIMED DEVICE FALCON IPSTOR DISK
/dev/dsk/c8t0d1 /dev/rdsk/c8t0d1

How to LVM it.

Thanks.
