Re: unable to extend vg as well as pe
If you're over 11i (11i v2 with the PHCO_35524 patch), you could resize disk online with vgmodify. Please check this:

Re: unable to extend vg as well as pe
Volume group "/dev/rdisk/disk11" does not exist in the "/etc/lvmtab_p" file.
Cross check and verify the disk ( DSF) existance.
&
Check for max PE per PV with vgdisplay command, this may give better idea

INH

Re: unable to extend vg as well as pe
No way to extend the pe_size, even in vgmodify.
Please check the max_pe in the VG has been set and try for possibility to change the same using vgmodify.
Refer the docs provided by Jose.
