The PV /dev/dsk/c10t1d5 is of 100gb capacity. when i tried to extend the volume group i have received the following message. This is not utilizing the 100gb size.
Kindly recommend me what are the steps i should perform.
# vgextend /dev/Test_vgworking /dev/dsk/c10t1d5
vgextend: Warning: Max_PE_per_PV for the volume group (1016) too small for this PV (3199).
Using only 1016 PEs from this physical volume.

Re: respond me immediate reg vgextend
You have to make a new volume group. Your current vg's LVM header has only 1016 PE's or physical extents. And it clearly calculates how many PE's your new PV needs, 3199.
"..vgextend: Warning: Max_PE_per_PV for the volume group (1016) too small for this PV (3199)..."

Re: respond me immediate reg vgextend
so if u have PE Size as 32 maximum size u can use in this disk is
32*1016=31G
and this is what is happening so you have to recreate the VG with high parameter
man vgcreate
-e max_pe increase it to some other number
-s PE size u can have big PE size if u have small number of max PE.
BR,

Solution>>Now is it possible to reconfigure the PE size?<<
NO,
Hope I have answered this Question, on the earlier do you remember, Hence you running HPUX 11.11 you can't change "PE = Size"
if its HPUX 11.31 -> you can use vgmodify command to change it.
in your case , you need to "recreate vg" no choice.

Now? No. When your use the vgcreate command, yes.

Re: respond me immediate reg vgextend
This is something you would have noticed before you create any VGs. Max PE/PV :)
Anyway, it is possible to amend the same on HPUX 11iV3 only but not on any below. I would prefer to have a backup on all the VG/LV and recreate the VG as required.

Re: respond me immediate reg vgextend
I have asked the DBA team to take a backup for these files and later i will recreate the vg with the "-e max_pe" and " -s pe_size" options.
Thank you All for responding to my thread.
I will assign points now and will close the thread.
