    I am running lpar2rrd on 2 of my nim servers (AIX 7100-05-05-1939) collecting data from 2 HMC's .The lpar2rrd script /home/lpar2rrd/lpar2rrd/load.sh  now fails with the following errors :-

    Hi,
    lpar2rrd is not part of AIX nor from IBM nor is it in the AIX Open Source Toolbox.
    So I am not sure why you are asking the question here.

    I suggest you take your question to the vendors XoruX at lpar2rrd.com
    You can purchase support there.
    Cheers, Nigel Griffiths.

    It could be a libpath problem.  I have found that some software requires the AIX libraries first and then the freeware/lib, and other software requires the reverse. Depends upon which libraries are included with toolbox rpms.

    Hi Peter,

    Those first two lines after load.sh look unusual to me, e.g. load.sh shouldn't complain about missing "commands".
    Looking at my copy of load.sh around line 403, there is a part that tries to find out the rrd version, and that version information is missing from 3rd line.
    IMHO re-download the lpar2rrd version you have installed, verify the checksum of the downloaded file, extract it and extract lpar2rrd stuff using: "gzip -dc lpar2rrd.tar.Z|tar xvf -" and compare the stock and your version of load.sh "diff -u dist/load.sh /home/lpar2rrd/lpar2rrd/load.sh".
    If there are differences, you might want to do an update, regardless of the version you are running.
    FYI at least in the past lpar2rrd has required perl version 5.8.x. This might have changed, or not, I don't know because I haven't checked/verified if the newer perl versions that are shipped with AIX, 5.28 etc, are compatible with lpar2rrd.

    Hi All,

    I logged this as a case with IBM support and they recommended the following ifxes for below apars be applied. and this has now resolved my issue.

    APAR IJ21688
    ========================== EFIX DESCRIPTION =============================
    Lib.pm module is missing in perl-5.28.1.0. Becuase of this missing file
    Math::BigFloat module isn't being loaded.
    $ perl -e 'use Math::BigFloat;'
    Couldn't load any math lib(s), not even fallback to Calc.pm

    APAR IJ24871
    ========================== EFIX DESCRIPTION =============================
    File Parserdetails.ini is not shipped with perl.rte 5.28.1.0

    Users may experience the following:

    I'd be curious what you were doing right before it started failing?  Did you update any rpms from perzl to IBM?  If so that's probably what broke it.  From my experience with lpar2rrd it doesn't like the IBM compiled rpms.  my hope is lpar2rrd stops referencing perzl rpms on their install page and makes it works exclusively with IBM rpms..

    Hi 

    Incidentally the lpar2rrd script starting failing after I had updated to service pack AIX 7100-05-05-1939 on both my NIM servers. It appears this service pack contained the following APAR which updated the perl package version and introduced the issue.

    IJ16717 Update the perl package to version 5.28.1

    Yes that would do it. You're going to have to tell lpar2rrd to start using it in the lpar2rrd.cfg file. I would recommend using perzl perl rpm v5.8.8 but you may be able to get the IBM version working

    lpar2rrd.cfg:

    PERL5LIB=/home/lpar2rrd/lpar2rrd/bin:/home/lpar2rrd/lpar2rrd/vmware-lib:/opt/freeware/lib/perl5/vendor_perl/5.8.8/ppc-thread-multi:/usr/opt/perl5/lib/site_perl/5.8.8/aix-thread-multi:/opt/freeware/lib/perl5/5.8.8:/usr/opt/perl5/lib/site_perl/5.8.8:/opt/freeware/lib/perl/5.8.8:/home/lpar2rrd/lpar2rrd/lib:/opt/freeware/lib/perl/5.24.1

    Perl version 5.10 is available on AIX toolbox. This is not same as AIX perl and it is with AIX toolbox terms and conditions. 
    https://public.dhe.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc/perl/perl-5.10.1-1.aix6.1.ppc.rpm

    But we always recommend to use latest version as there may be security vulnerabilities and bugs.

    I haven't had a lot of luck with IBM rpms and lpar2rrd. The way lpar2rrd is built it is looking for perzl compiles, this is especially true with perl since it requires perl mods that are only available from perzl. otherwise you're going down a rabbit hole of cpan..

    lpar2rrd works easily with the latest aixtoolbox perl, just install the dependencies as usual and set the PERL5LIB in lpar2rrd.cfg.

    heres my perl mod install script if this helps (use cpnaminus, you will thank me later):

    #!/usr/bin/ksh

rm -rf /home/nmon/lpar2rrd/aix_lpar2rrd_perlmods/*

    Hello C- -T,

    May I ask you how you solve the dependencies problems with the Perl modules? We are missing LWP::Protocol::https and to install this module with

    perl -MCPAN -eshell

    we need another Module "HTML-Parser".

    Thanks in advance for your help...

    Joerg

    Hi,

    I wrote a script that uses "/opt/freeware/bin/cpanm" aka App::cpanminus to install all dependencies that lpar2rrd requires.

    Please note that the script removes two files, or symbolic links. My environment has a long and sordid past, so I had some remnants of old openssl libraries installed by old  openssl RPM packages

    I've remove the script from this post because line brakes were messed up. I'll try to upload the script.

    Please note that you must also modify PERL5LIB in your lpar2rrd/etc/lpar2rrd.conf file. Below is the one that works for me, which contains extra directories and directories should arranged in more optimized order.

    PERL5LIB=/home/lpar2rrd/lpar2rrd/bin:/home/lpar2rrd/lpar2rrd/vmware-lib::/home/lpar2rrd/lpar2rrd/aix_lpar2rrd_perlmods/lib/perl5:/home/lpar2rrd/lpar2rrd/aix_lpar2rrd_perlmods/lib/perl5/ppc-aix-thread-multi:/home/lpar2rrd/lpar2rrd/aix_lpar2rrd_perlmods:/opt/freeware/lib/perl5/vendor_perl/5.8.8/ppc-thread-multi:/usr/opt/perl5/lib/site_perl/5.8.8/aix-thread-multi:/opt/freeware/lib/perl5/site_perl/5.22.0/ppc-aix-thread-multi:/opt/freeware/lib/perl5:/usr/opt/perl5/lib/site_perl:/opt/freeware/lib/perl5/site_perl/5.22.0:/home/lpar2rrd/lpar2rrd/lib

    It seems there is something different on our system... we don't have "/opt/freeware/bin/cpanm" there is only "cpan"

    Hi,

    You have to install the CPAN minus module/app before my script works.
    The CPAN minus is required due to the web of dependencies between the perl modules.
    The module can be found here https://metacpan.org/pod/App::cpanminus and there are installlation instructions aswell on that page.

    Good Morning Esa,

    thanks again for your help. I installed cpanminus, but then getting errors from "tar". CPANM is using wrong options for "tar" and can not unpack the downloaded package.
    In the meantime I got it managed to install the missing perl mods with cpan. It didn't work before, because there was a link set in /usr/bin to a non-compatible CPAN version. After setting the link to the correct AIX-Toolbox version it worked.

    Thanks a lot for your support.

    Joerg

    Hi,

    The cpanminus app/module uses "modern" tar options when unpacking stuff, e.g. it does not work with "/usr/bin/tar",  but it works with "/opt/freeware/bin/tar", which is the reason I added "/opt/freeware/bin" to the beginning of the PATH environment variable in my script, before running "cpanm".

    $ which tar
    /usr/bin/tar
    $ PATH=/opt/freeware/bin:$PATH
    $ which tar
    /opt/freeware/bin/tar
    $ ​
