Typically this is due to running an old firmware or version of OMSA, see mention here
Actually I reached out to the owner of the server and they didn't mind loosing the history on the node because it was being moved from a test to a production environment so I changed it to poll via SNMP.
The drives are showing now!
ah yeah theres that too, some stats only show up in SNMP, others in WMI
Discover with SNMP
You can see the difference between using the SNMP and WMI to monitor the server hardware health：
Dell OSAM Agent v8.4 :
Keegan, thanks for those links!
So if I'm reading that correctly, based on the chart SolarWinds does not monitor the drive hardware health when using WMI node polling. Yes, OMSA 8.4 is installed on the Window's server node.
Or is there any way to configure Solarwinds to enable this feature?
To clarify, management prefer's to monitor all nodes via WMI. I got scolded when I switched it to SNMP and was told to switch it back.
For any node has been polled with SNMP in the past you can enable some UNDP pollers to check the array info, along with the other sensors that aren't available via the Dell OMSA tool using WMI
OID = ARRAYDISKNUMBER
OID = arrayDiskName
OID = arrayDiskSerialNo
OID = arrayDiskLengthInMB
OID = arrayDiskComponentStatus
OID = CONTROLLERNUMBER
OID = controllerName
OID = controllerComponentStatus
OID = SYSTEMSTATECHASSISINTRUSIONSTATUSCOMBINED
OID = BATTERYCHASSISINDEX
OID = batteryIndex
OID = batteryStatus
OID = batteryLocationName
The WMI interface for Dell OSMA only provides the following information：
Dell WMI poller
Dell WMI Classes are polled from the "root\cimv2\dell" namespace:
- CIM_Tachometer - Fans
- CIM_TemperatureSensor - Temperature
- DELL_PowerConsumptionWattsSensor - PoweSupply
- DELL_PowerConsumptionAmpsSensor - PoweSupply
- CIM_VoltageSensor - PoweSupply
Does not contain disk，you can use WBEMTEST to check.
