How do I find the system's disk capacity?

Question

I run the command df -g to get the GB block sizes in the second column (left to right). If I want to get the total capacity for all hard disks, which command should I use?

OS is AIX.

Answer 1

for i in `lspv | awk '{print $1}'`
do
    echo $i
    lsattr -El -a size_in_mb $i
done

Or via ODM:

odmget -q"name like hdisk* and attribute=size_in_mb" CuAt

Answer 2

The following command will help you to find total size of each hdd on your system.

fdisk -l  | grep Disk

Answer 3

I know you didn't ask this directly but df -h lists created partition sizes which is sometimes more useful.

Answer 4

Not sitting in front of an AIX system, but try this:

df --total -h

Edit: this won't work in AIX. But I'll leave this here for anyone else who might need it on GNU systems.
