I got this error when I tried to add a SNMP HP ProLiant Physical Disk Sensor for HP Proliant DL 380 G7 with Windows 2012 R2 in our monitoring solution from Paessler (PRTG). The SNMP HP ProLiant System Health, Network and Storage Controller Sensor works fine.
HPE Insight Management Agents and HPE Insight Management WBEM Providers for Windows are installed.
An SNMP walk against OID 126.96.36.199.188.8.131.52.2.5 (used by Paessler for this sensor) works without errors but also without result.
I found some guys with the same probleme and a solution: The problem was the disk (controller) driver. Installed was v184.108.40.206, which seems to be a standard Microsoft driver. With the original HPE controller driver (for us 220.127.116.11) it works.
