Hi Guys,

I don't understand this script,

What does this line " cd `ls |grep -v tar`/disks" here????

Code:

-bash-3.00$ /usr/local/bin/sudo cat /users/sysmgr/ios
Password:
#!/usr/bin/bash

cd /opt/SUNWexplo/output/
cd `ls  |grep -v tar`/disks
echo `pwd`
cp iostat_-E.out /users/sysmgr/ionew
diff /users/sysmgr/ionew/iostat_-E.out  /users/sysmgr/ioold/iostat_-E.out >/users/sysmgr/iodiff
if [ -s /users/sysmgr/iodiff ]
then
echo
else
echo `pwd`
cat /dev/null >iostat_-E.out
cd /opt/SUNWexplo/output
echo `pwd`
rm -f `ls |grep explorer.844d540d.server1|grep tar`
h=`ls |grep -v tar`
tar cvf  $h.tar $h
gzip $h.tar
fi
cp /users/sysmgr/ionew/iostat_-E.out /users/sysmgr/ioold


-bash-3.00$

it showing me this errors:-

Code:

Your "cron" job on server1
/usr/local/bin/sudo /users/sysmgr/ios  #HD404710

produced the following output:

Lets see...

cd `ls |grep -v tar`/disks

so its trying to change directory to: (something without 'tar' in it)/disks. it depends on where you run this, whether it will work or not.

pseudo:

ls current directory
grep for names without tar in it
append it to /disks
cd to (result)/disks

Does it mean disks is created at "/" ?

szboardstretcher · 08-27-2013, 09:54 AM

eh.. let me see here..

cd /opt/SUNWexplo/output/; cd `ls |grep -v tar`/disks

So this 'disks' directory is a subdirectory somewhere in /opt/SUNWexplo/output.

so go there, then try a:

find . -name disks

If you'd like to know where the disks directory is.

no its not there, disks is not there.

Code:

-bash-3.00$ ls -la disks
disks: No such file or directory
-bash-3.00$ pwd

-bash-3.00$

This how it produces output when it runs well on other server.

Code:

Your "cron" job on server2
/usr/local/bin/sudo /users/sysmgr/ios    # HD 404710

produced the following output:

/opt/SUNWexplo/output/explorer.833c0503.server2-2013.08.26.00.00/disks

Above are just starting few lines of big output of that script.

cp iostat_-E.out /users/sysmgr/ionew

cp: cannot access iostat_-E.out

Result of a buggy script... you should always make sure the file or dir exists and has sufficient read and write permissions prior to use them anywhere in the script.
So above cp erroris because of insufficient permissions on the file.

Quote:

tar: explorer.844d540d.server1-2013.08.26.00.00: Is a directory
gzip: explorer.844d540d.server1-2013.08.26.00.00 is a directory -- ignored
gzip: iostat_-E.out.gz already has .gz suffix -- unchanged
gzip: stderr.21762.tar: No such file or directory

Again not checked for a file and nor for existing archive.

EDIT:

assuming you dont have sufficient permisions to change the script... so for this to work fine you have to apply correct permissions on the file "*.out" and and rename the .gz file to something else. That should be it.

NO. this scripts works fine on other solaris 10 server.
this script has started giving errors when we upgraded Sun Explorer version from 7.3 to 8.0. on this machine.

jlliagre · 08-28-2013, 02:44 AM

Then downgrade explorer to 7.3 or upgrade your script to something that work with explorer 8.0.
If there is no such update, find out the people who wrote the script and ask them for support.
If not available, figure out why and what something changed in the directory layout between the explorer releases.

Actually the script is sure a buggy script.. reasons i have already mentioned in the last post... it was working fine on other servers because they have the required file and permissions set already and hence it executed.. while when you upgraded a server and it dont have the required sets of permissions and already a archive present, the script should have statements checking that..

for the solution i already have mentioned in EDIT section of last comment.

Firerat · 08-28-2013, 03:51 PM

that script is .. bad and not as in good.

Warning:
I have never used solaris.
The below is Untested...even on gnu/linux
may use 'features' not available to you
no real error checking/reporting..

Code:

#!/usr/bin/bash

Output=/opt/SUNWexplo/output
iostat_err=${Output}/*/disks/iostat_-E.out
LastIOStat=${Output}/.LastIOStat

# initial LastIOStat
[[ ! -e $LastIOStat ]] \
  && ( echo "ffffffffffffffffffffffffffffffff  ${iostat_err}" > $LastIOStat )

function Archive() {
Tar=${Output}/*/
TarExt=.tar.gz

tar avcf ${Tar/%\//$TarExt} -C ${Output}/ */ 
return $?
}

function Laststat(){
md5sum ${iostat_err} > ${LastIOStat}
return $?
}

[[ -s "${iostat_err}" ]] \
   && (
     md5sum --status -c $LastIOStat || ( Archive && Laststat );exit $?
   ) || exit 0
fi

Notes:

tar will overwrite existing archive ( unless you pass append arg.), so no need to delete
The above assumes your tar can compress, and is capable of automagical determination of compression program
using md5sum to determine if iostat_-E.out changed ( so you get to keep it )
No real error checks in above script
Warning: it looks like you may have multiple explorer.*.server*, if that is the case then the original nor the above 'deal' with that
will do nothing until you determine correct location of iostat_-E.out
( or you get some actual IO errors )

Hi Guys,
I changed bash to ksh, as it was initially.
I removed this two files:-

Code:

-rw-r--r--   1 root     root          34 Aug 31 14:14 iostat_-E.out.gz
-rw-------   1 root     root          88 Jun 25 10:30 stderr.21762

from above location and script just ran well , without any error.

I just compared the files with other servers where this scripts runs well and these 2 files were not there.

Hopefully , I think I have got the solution now.

Thanks a lot for all your replies.

SAbhi · 08-31-2013, 10:26 AM

Thats exactly what you were told in my last post.

manalisharmabe · 09-17-2013, 12:10 AM

Hi Guys,

I Just reopened this thread due to one query.

Whenever i run this comand /usr/local/bin/sudo /users/sysmgr/ios on command line only

this line /opt/SUNWexplo/output/explorer.833b0e87.server1-2013.09.16.00.00/disks
get produced but when I again run it, it get executed fully like this:-

Code:

In first attempt this is how it attempts in mail in first attempt:-

Code:

Your "cron" job on server1
/usr/local/bin/sudo /users/sysmgr/ios
produced the following output:
/opt/SUNWexplo/output/explorer.833b0e87.server1-2013.09.16.00.00/disks

What could be the problem that it does not hget executed in first run?

Does it mean that it does not send system information to Sun Explorer Portal?

Well, After first run I did check /opt/SUNWexplo/output folder but nothing speacial get created there.

Please advise.

Manali,

first of all whenever you are posting a new issue, use a new thread.

i cant say i understood what you posted...

are you running this command command as a cron job or in a terminal seperately ???
if from a cron share the con entry,
also share

Code:

ls -l /opt/SUNWexplo/output/explorer.833c0503.server1-2013.09.16.00.00/disks
