Hi again, 
I think I know the cause of this issue, but I'll appreciate your confirmation. Store2rrd version 2.50

Issue: No graphs in SAN switches,

I think issue is due to an up upgrade of openssl package because of an audit requierement.

I'll upload logs in few minutes.

Thanks once more.

Cheers from Andorra.

Pavel

yep, exactly, it will not work with higher openssl

igalvarez

Hi Pavel,

it will not work only for AIx systems? Or the issue is the same for Linux? Any work future work arround for this issue?

In our case we can not downgrade openssl (AUDIT requierements)

Pavel

AIX is affected, snmp package require some openssl.

BTW this openssl is not used anyhow, all programs using system openss (lslpp -L| grep -i openssl), it is just dependency , nothing else

Upgrade to higher snmp packages could be a solution but do not do it, we have bad experience with it on AIX

Linux is not affected anyhow by this, it is solely AIX dependecy hell

igalvarez

Thx pavel,

openssl was updated as  part of a new version of httpd server (also upgraded). I'll try to upgrade snmp pkgs.

Agree, I know AIX package manager is very bad.

Maybe it's time to migrate lpar2rrd/stor2rrd to RHEL on intel.

cheers

igalvarez

Last question Pavel,

If I install from scratch lpar2rrd/stor2rrd in RHEL, is possible to migrate data already stored in AIX to Linux?

I'd not like to lost data from  lpar2rrd/stor2rrd.

Pavel

yes, however it is not easy if you want to do it youself.

if you have support we can provide you scripts.
