</code>

Solution
<code bash>
ldconfig

Par info 
<code ->
# rpm -qf /opt/dell/srvadmin/lib64/libdcsupt.so.8
srvadmin-deng-8.2.0-1739.8348.el7.x86_64
</code>


==== Pb 2


<code ->
# docker exec -ti omsa82-snmp omreport chassis fans
Error! No fan probes found on this system.
</code>

Solution :
Version plus récente de Dell openmanage


== Supervision 

=== Pb

<code ->
# /usr/lib64/nagios/plugins/check_openmanage -H 172.18.205.2
SNMP ERROR [cooling]: The requested entries are empty or do not exist
</code>

Le pb vient d'openmanage, peut-être la version n'est pas assez récente

La commande suivante doit fonctionner
<code bash>
omreport chassis fans
