system inventory

Alain Tesserot — Fri, 15 Jul 2005 13:05:05 GMT

I have several servers and many disks. How do I get information for disk size and free space on each disk for a report.

To get the disk info, use the 'diskinfo' command

As to free space, many variables can play a role hee. Are you running a cluster? Do you have shared disks?

On the basic level, a 'vgdisplay -v' command can provide that info. How many 'FREE PEs' do you have?

I know about the diskinfo command. The problem is that we have many disks. Is there a way to query several device files at once?

Check out this URL site and get the cfg2html script.

Will provide lots more info as well.

With remsh configured on a central server, I have a script that cycles through all the servers to execute a bdf command. It's similiar to this:

for SERVER in node1 node2 node3 ;do
echo $SERVER
remsh $SERVER -n /usr/bin/bdf
done

you can add other commands like pvdisplay or vgdisplay to match the information you desire.

This can also be done if you have Servicecontrol Manager installed and configured.

With remsh or ssh to can issue 1 command and a script can cycle through the servers in your environment and fetch/report that info for you.

Many ways to do it.

nicket tool
bdf
diskinfo
print_manifest (ignite needs to be installed)
SCR (System configuration Repository software)
cf2html

I can do diskinfo /dev/c0t0d0 and get disk information for that disk but if I have 100 disks, how do I get diskinfo to display all devices?

Re: system inventory

An example,

use a shell script to gather the disk device names (/dev/dsk/cXtYdZ). In that script have a for loop that goes through each device and executes the diskinfo command against that device.

#!/usr/bin/sh
for DISK in /dev/rdsk/c*
do
echo "diskinfo ${DISK}"
diskinfo ${DISK}
echo ""
done

Start of an example script.

This will parse the lvmtab file and get the device names. It will convert the devices names to raw device names. Reading each line it will execute the diskinfo command.

strings /etc/lvmtab | grep /dev/dsk | sed 's/dsk/rdsk/g' | while read line
do
diskinfo $line
done

Remember, if there is MCSG or disk sharing in effect, do not trust these results. This is on a basic level of getting the requested info.

you can also get all the disks recognized by the system from ioscan:

ioscan -funCdisk |grep dsk |awk '{print $2}' |while read DISK ;do
diskinfo $DISK
done
