Hi Shiv:

With all due respect, you would learn a great deal more by posting *what* you have tried to create and then asking for help where you are stuck.

Regards!

You should also check the di tool available at Merjin's software archieve:

http://mirrors.develooper.com/hpux/downloads.html

di -d G

will give you filesystem information in GBs.

Is it possible to print the summary of total available,used and free in GB ?

Hi Shiv:

#!/usr/bin/sh
bdf | awk '!/Filesystem/ {
s2+=$2;s3+=$3;s4+=$4;
printf("%-18s %10d %10d %10d %4s %s\n",
$1,$2/1024/1024,$3/1024/1024,$4/1024/1024,$5,$6)}
END{printf "%-18s %10d %10d %10d\n","TOTAL",
s2/1024/1024,s3/1024/1024,s4/1024/1024}'

...while not formatted to be pretty, I think this gives you want you want. Columns do not quite add up due to rounding.

Hi (again) Shiv:

I should have said (of course) that "Columns do not quite add up due to integer truncation."

Regards!

Hi Shiv:

This last hack does a better job of formatting the output and replaces the printf() integers with rounded reals (via "%10.2f"). You will find that the columnar totals are much closer to their expected values.

#!/usr/bin/sh
bdf | awk '
BEGIN{printf "%-16s %10s %10s %10s %5s %s\n",
"Filesystem","GB","Used","Avail","Used","Mounted_On"};
!/Filesystem/ {
s2+=$2;s3+=$3;s4+=$4;
printf("%-16s %10.2f %10.2f %10.2f %5s %s\n",
$1,$2/1024/1024,$3/1024/1024,$4/1024/1024,$5,$6)}
END{printf "%-16s %10.2f %10.2f %10.2f\n","TOTAL",
s2/1024/1024,s3/1024/1024,s4/1024/1024}'

Regards!

Use this:

# bdf | awk 'BEGIN{ print "Filesystem GBytes Used avail %used Mounted on"}{ if ($0 ~! /Filesystem/) { printf "%s %6.5f %6.5f %6.5f %3s %s\n",$1,$2/1024/1024,$3/1024/1024,$4/1024/1024,$5,$6;}}'

Thanks everyone for helping me!!

I have checked that both disks are available on the servers. Attached disks and SAN disk.

How to find out how much SAN disk is used, free ?

I mean i want separation of usage of SAN and attached disks both ?

Thanks,
Shiv

Shivkumar,

Depends on what you are looking for and from what perspective. Disk space available per LV, per VG. You might also have disks available on your system that have not been pvcreated but are available. Can you be more specific?

Hi SHiv:

# diskinfo /dev/rdsk/cXtYdZ

...will return the size of a disk. Note the use of the raw (character) device -- 'rdsk'.

See the manpages for more information, too.

Hi Shiv,

You can use the attached script finding out un-used disks,

Note : It works when you have Solution Enabler installed on your server.

The syminq program is part of the EMC disk utilities package for newer disk arrays. Since EMC disk arrays are very expensive, you would definitely know if you have this package of tools.

As far as locating disks on your system which are not used, that is, not part of any disk volume group, you can run SAM and in the disks section, start creating a new volume group. The first step in SAM will show you potential disks you can use for a new volume or to extend an existing volume.

Here is the script for disk space in GB.

#!/usr/bin/ksh

echo "Filesystem Gbytes used avail %used Mounted on"

bdf $1 | grep -v Filesystem | awk '{ printf("%s %10d %10d %10d %4s %s\n",$1,$2/1024/1024,$3/1024/1024,$4/1024/1024,$5,$6)}'

And you can find the script for used and available space for disks as ana attachment. It gives you detailed information about PVs,VGs and LVs. you only have to add your mail address to script.
