    lscfg doesn't actually show the size: it just shows the description in the
    VPD - which is not always present.
     
    For disks which are not in a VG you can use lsattr -El hdiskX -a size_in_mb.
    But be warned! This will not be the same as in lspv output as lsattr uses
    1MB=10^6 bytes and lspv uses 1MB =2^20 bytes. Also, you can lose a bit of
    space if you have a large partition size on a small disk.
    lsattr may not work for all disks: it doesn't work with our HDS SAN, for
    example.

lspv -p hdisk0    - show allocated and unallocated PPs
lscfg -vl hdisk0  -  show what size disk

Subject: How to compute free space on Physical Disks?
I need to find the "Total disk size" and "Free Space" on all my Physical
disks.
Right now I am doing this:
"lspv hdisk0"
And grabbing the "TOTAL PPs" and "Free PPs" fields.
Is this right, or is "Free PPs" the amount of sapce that has not been
assigned already.
Thanks in advance
