I need  a script to run commands on all servers and get the output:

I want a script in AIX and Linux

login to server run lsvg vgname
rootvg
appvg

lsvg rootvg
TOTAL PPs:      135 (34560 megabytes)

get the below value and divide by 1024 and do the same for appvg

and then I need to sum up the total and give the value as below


server12  totalstorage 120Gb
server23  totalstorage 248Gb

I will put all the server name in servername.txt

cat servername.txt

server12
server23
server34
etc

I need the same for RHEL as well

like vgdisplay anf then get then sum up all the vg's

I have a common user id on all servers with the same password and would be able to get the output

Please provide all the steps to for this script.

Hi,

let's start with AIX:

while read server; do
  ssh -n userid@$server 'lsvg -o | lsvg  -i' |\
    awk -v HO=$server -F"\\\(|m" '
           /TOTAL PPs:/ {SUM+=$2}
            END {printf "%s totalstorage %.0fGB\n",HO,SUM/1024}'
done < servername.AIX.txt


Working on the Linux version ...

Here it is:

while read server; do
  ssh -n user@$server 'vgdisplay' |\
   awk -v HO=$server '
          /VG Size/ {if($4=="TB") $3=$3*1024;  SUM+=$3}
            END {printf "%s totalstorage %.0fGB\n",HO,SUM}'
done < servername.Linux.txt


If you have Linux VGs < 1 GB or >= 1 PB please let me know!

Of course there is - use output redirection.

Either add it to the script at the end of the "done" line:

while read server; do
  ssh -n userid@$server 'lsvg -o | lsvg  -i' |\
    awk -v HO=$server -F"\\\(|m" '
           /TOTAL PPs:/ {SUM+=$2}
            END {printf "%s totalstorage %.0fGB\n",HO,SUM/1024}'
done < servername.AIX.txt >> outputfile.txt

or add it to the command line when starting the script.

Assuming you called the script myscript:

myscript >> outputfile.txt

On Linux it's exactly the same!
