"man vgcreate" and "man lvmpvg" offer some useful information on PVGs.

Hello Shreejesh

"For basic issue you need to refer books like R Rehmaam or HP administration guide"

For your information:-

Physical volume is the actual physical disk drive. To use a disk with LVM (and hence to mark it as a
physical volume), some data structures are created on the disk. The physical volumes use the same
device file names as are used with the disk drives.

We use PVG when we want to use striping with Mirroring so we keep all the striped PVs in a PVG and then mirror one PVG with another...

Once we create a PVG vg sees it as a complete LV .. no matters how many disks are their in PVG..

To set up this we need minimum 4 disks so each PVg will have 2 disks and u can stripe them and then they can be mirrored across another PVG..

This kind of setup helps us in getting more I/O.. so speed is higher and at the same time we have a mirror as well..

Hi:

You will find that the manpages for 'lvm(7)' provide a useful overview of basic terminology and concepts.
