physical volume and physical disk.
Hello,

I need explanations about physical disks and physical volumes. What is the difference between these 2 things?

In fact, i am trying to understand what the AIX lspv2command does.

Thank you in advance.

Hi,

A physical disk is a single disk... a physical volume is what defines a group of physical disks ( it can be only one disk, but you can add more ), like in a RAID device...

The lspv will show you information about a physical volume on a volume group ( a volume group can be anything [ we're talking sbout disks ] that is grouped to look like one ).

It's not difficult, just learn the right terms...
