Zabbix can't see IPMI sensors

[gorekBoy]

Hi

I would like monitor CPU temperature on IBM x3550 M4 server via IPMI but Zabbix can't see 2nd CPU temperature sensor.
For 2nd CPU temperature item zabbix says "sensor or control CPU 2 Temp@[192.168.xx.yyy]:623 does not exist"
but for the same item for CPU1 everythings ok.

Ipmitool for this server return:

$ ipmitool sdr type temperature
Ambient Temp     | 32h | ok  | 12.1 | 20 degrees C
CPU 1 Temp       | CBh | ok  |  3.1 | 32 degrees C
CPU 2 Temp       | CCh | ok  |  3.1 | 29 degrees C
PCI Riser 1 Temp | 33h | ok  | 16.1 | 30 degrees C
(..)

so "CPU 2 Temp" sensor exist and can return value.

I run zabbix server with DebugLevel=4 and grep logs for 'Added sensor' string but I can't see 'CPU 2 Temp'.

Can somebody please help me?

Thanks
