Re: extending a physical volume
I will admit that the -x option of vgcreate looks quite exciting though!

SolutionAs our esteemed colleague Clay Stephenson would say - That dog won't hunt.
You won't be able to "extend" the PV or LUN & leave the data untouched & available.
The better alternative would be to create another, new LUN & vgextend the Volume Group, lvextend the Logical Volume & increase the filesystem size with fsadm. This you could do w/o touching the data, provided you have the OnlineJFS product.
HTH,
Jeff

Re: extending a physical volume
The '-x extensibility' option can be expressed as '-x y' or '-x n'. 'y'es allows the allocation of new physical extents on the physical volume(s) specified by the 'pv_path'(s) or 'pvg_name' used during the 'vgcreate' or 'vgextend'.
The default value is 'y'es, which allows the (later) addition of physical extents on the physical volume by an 'lvextend' or 'lvcreate'. A value of 'n'o prohibits addition of physical extents on the physical volumes so set.
'pvchange -x [y|n]' allows you to alter the extensibility attribute.
The idea is that you can prevent selected physical volumes from being candidates for the allocation of physical extents on them when they are chosen, even when specified in a 'pv_path' or 'pvg_name' argument.
