IPMI partially work.

IPMI is working fine with ipmitool, but partially with zabbix.

A request to sensor "Planar Temp" works well but a request "Voltage 1" or "Voltage 2" doesn't work while it works with ipmitool :

Log zabbix :
In substitute_simple_macros (data:'ipmi.get.voltage1')

In substitute_simple_macros (data:'10.10.10.65')
IPMI Host 10059 is unreachable. Skipping [ipmi.get.voltage2]

But by ssh on the zabbix server :

1. ipmitool -H10.10.10.65 -UXXX -PYYY sdr get 'Voltage 1' | fgrep "Sensor Reading" | awk ' {print $4}'
   232
   # ipmitool -H10.10.10.65 -UXXX -PYYY sdr get 'Voltage 2' | fgrep "Sensor Reading" | awk '{print $4}

   '
   232

So...
