Add new disks in an existing volume group

[Ponce]

I want to add new 36Gb disks in a existing volume group created with 18Gb in an HP-UX 11.0 L1000 server.
When I use "vgexteng", I got the warning that max physical extend has been reached. So only half of the new disk space is used.
Is there any way to increase this max physical extend on an existing voulme group to take into account all the space of my new disks?

Whenever the Vg is created its max PE is defaulted to the largest size hard diski.e. as in your case 18Gb.
you cannot use a 36GB hard disk with increasing the MAX PE.

The only way is to re-create the VG

Unfortunately no.

You can only re-create the volume group with a "vgcreate -e" option or "-s" to increase the size of the extents.

Or convert your LVM configuration to VxVM. You won't have the problems of Max Extents per PV on VxVM... So you can start off with a small LUN ona diskgroup (VG), and subsequently add any sized LUN you want (up to 1 TB) and you'll be able to use all space!
