Disk Capacity and Useage 1

[kovacsa]

Hello ...

Does anyone know what command(s) to use to find out the physical disk capacity and what portion of it is being used on a machine running AIX 4.3.1?

Thanks in advance,

kovacsa

Check this FAQ: faq52-2441

It gives you a report of disks on the system, how many physical partitions are used and free, and what is on the disks. You can read the script to see the commands to use if you don't want to use the script.

Here is a little script that may help

#set -x

# display.free.dasd - script to display free dasd space on system/node/whatever

print "DISK PP Total Used Avail Volume Group"
#for i in `lspv | awk '{ print $1 }'`
disks=`getlvodm -C | awk '{ print $1 }'| sort -k 1.6,1n `
case "$1"
in
y)
for i in $disks
do
`lspv $i 1>/dev/null 2>eouchk`
if [[ `ls -ail eouchk | awk '{ print $6 }'` -eq 0 ]]
then
PPSIZE=`lspv $i | grep "PP SIZE" | cut -c 20-23`

Hi kova

Simply u can have the solution like this

step 1:The physical capacity of the disk can be found by
#bootinfo -s <hdisk#>

u will get pv capacity in mb

step 2 :#lspv hdisk#

It shows its utilization...in terms of pps and bytes
