[Problem] SNMP Failed on Dell Server

Hi All,

I'm currently managing  Dell servers: M620,M610,R720,R620,R610..... I am using SNMP to collect informations from my servers. I have some problems with SNMP:

I setuped a collector server ( CentOS) and full mibs file (10892, sotragemanagement,iDRAC-SMIv2,iDRAC-SMIv1...) , using snmpwalk to collect infor from agent (CentOS, M620). On agent server, I already setuped OMSA agent, full mibs (10892, sotragemanagement,iDRAC-SMIv2,iDRAC-SMIv1...) and all of services were working correctly:

[root@agent mibs]# /etc/init.d/dataeng status
dsm_sa_datamgrd (pid 43827 43770) is running
dsm_sa_eventmgrd (pid 43879) is running
dsm_sa_snmpd (pid 43938) is running

I have some issues with getting idrac infor, power, thermal of server

1, I used oids in IDRAC-MIB:

Object ID 1.3.6.1.4.1.674.10892.5.1.1.1.0

Object ID 1.3.6.1.4.1.674.10892.4.5000.10.7

[root@collector ~]# snmpwalk -v2c 10.72.2.239 -c Mi725005d1 1.3.6.1.4.1.674.10892.4.5000.10.7
IDRAC-MIB-SMIv2::server3.4.5000.10.7 = No Such Object available on this agent at this OID

- out-of-band OIDs require iDRAC-MIB.txt to get info. But I don't see this file in agent location (root/.snmp/mibs). I downloaded dell mib files from DCMIB73_A00: DELL-RAC-MIB.txt, iDRAC-SMIv2.mib, iDRAC-SMIv1.mib but did not have DRAC-MIB.txt.

Where can i download this file?

2, I already used snmpwalk to get power, thermal but not worked.

[root@collector ~]# snmpwalk -v2c 10.72.2.239 -c Mi725005d1 1.3.6.1.4.1.674.10892.1.700.10.1  

MIB-Dell-10892::coolingUnitTableEntry = No Such Instance currently exists at this OID

[root@collector ~]# snmpwalk -v2c 10.72.2.239 -c Mi725005d1 1.3.6.1.4.1.674.10892.1.700.12.1 

MIB-Dell-10892::coolingDeviceTableEntry = No Such Instance currently exists at this OID

[root@collector ~]# snmpwalk -v2c 10.72.2.239 -c Mi725005d1 1.3.6.1.4.1.674.10892.1.600.10.1
MIB-Dell-10892::powerUnitTableEntry = No Such Instance currently exists at this OID

--> Is there any problem with my server?

Could you help me?

Many Thanks,

nampnx
