MD3000 alerts and snmp problem

Hello!

I have MD3000 Storage.

Its connected to PowerEdge NX1950 via SAS 5/E

on NX1950 installed:
    Windows Server 2003 x64
    Dell OpenManage Server Administrator
    Dell Modular Disk Storage Manager
      

OMSA does see MD3000 connected and its disks and MDSM does it too.

The issue is here:

If I have problem on MD3000 I can see it in MDSM, but  not in OMSA.
OMSA always shows that enclosure works fine.
SNMP requests to OMSA also shows that enclosure is in OK state. At the same time MDSM agent sends snmp trap with problem.

I dont have to fix OMSA (I dont need it at all) if snmp will work without it, but, as I understand, I need OMSA if I want snmp to work.

Thanks for any advice.
