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.

Which OS? I'm guessing Linux?– growseMar 31, 2011 at 14:15

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
Total size of all disks (sum). Output in GB.
TOTAL=0; for DISK in $(lspv | awk '{ print $1 }');do SIZE=$(bootinfo -s $DISK); TOTAL=$(echo "$TOTAL + $SIZE"|bc); done; echo "$TOTAL / 1024" | bc
Used Commands
lspv: lists all disks
bootinfo -s: gives you the real size of the disk
bc: used for calculating

1Thank you for this. However, we do prefer at least a little explanation (such as what command you're getting the data from, I assume lspv plus bootinfo) and the reason for the scripting around it. Nonetheless, an upvote to you. Jun 4, 2014 at 11:00
For AIX try the following, which does NOT need to be run as root:
get_conf DISK_SIZE /dev/hdisk0
The output will be returned in MB.

In case someone's still looking for the answer, it is getconf now in AIX 7.2 Oct 11, 2023 at 23:36
The following command will help you to find total size of each hdd on your system.
fdisk -l | grep Disk
I know you didn't ask this directly but df -h lists created partition sizes which is sometimes more useful.
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.
