My Dell PowerEdge sensor fails to validate disks and I can’t add it. What can I do?

Votes:

0

The SNMP Dell PowerEdge Physical Disk sensor does not work with some hard disks on the host. It shows the following error message:

The validation of at least one of the new objects failed because of the following:
Disk: Required field, not defined.
The object was not created.

Why does this error appear on some hosts? How can I solve this disk validation issue?

Solving a Dell PowerEdge physical disk validation error

The SNMP Dell PowerEdge Physical Disk sensor monitors disks in PowerEdge servers using Dell OpenManage Server Administrator or iDRAC. This sensor also needs the serial number of a particular disk to recognize it on the system and to be able to monitor it. This is necessary because the order can change in the retrieved list of disks.

If the sensor cannot find a serial number on a disk in the system when you want to add the sensor, you get the error message The validation of at least one of the new objects failed because of the following: Disk: Required field, not defined.

Restart the PowerEdge server

In this case, shut down your PowerEdge server and restart it. The affected disks on the system now provide the serial numbers so that the sensor can work as expected.

You can check if there are missing serial numbers with the free SNMP Tester. Run this tool on the probe system on which the PowerEdge sensor runs and execute an SNMP walk with the following base OID:

1.3.6.1.4.1.674.10892.5.5.1.20.130.4.1.7

If you see empty entries, for example, 1.3.6.1.4.1.674.10892.5.5.1.20.130.4.1.7.1 = "", the serial number is missing for this disk.

FYI, I avoided having to restart the server by restarting the SNMP service. This resolved the validation issue.

Is there a way to modify the sensor to not require a serial number, but look to some other unique identifier? I increasing have ran into this issue where iDrac does not report a serial number to certain disks.

Hello,

the sensor cannot be changed here, it always uses serial numbers, as normally they should be present and offer a reliable way to discern disks (as names or other properties are arbitrary).
