got no metrics from Dell IDRAC due to duplicate devices

[ulikl]

Hi, like in https://github.com/jenningsloy318/redfish_exporter/issues/57

we get with your latest version and iDRAC firmware version 6.00.02.00 no metrics, but just errors

An error has occurred while serving metrics:

14 error(s) occurred:
* [from Gatherer #2] collected metric "redfish_system_pcie_device_state" { label:<name:"hostname" value:"" > label:<name:"pcie_device" value:"LPe31002-M6-D 2-Port 16Gb Fibre Channel Adapter" > label:<name:"pcie_device_id" value:"96-0" > label:<name:"pcie_device_partnumber" value:"0RXNT1" > label:<name:"pcie_device_type" value:"MultiFunction," > label:<name:"pcie_serial_number" value:"...." > label:<name:"resource" value:"pcie_device" > gauge:<value:1 > } was collected before with the same name and label values

Our devices list contains duplicates:

curl -k -u ... https://.../redfish/v1/Systems/System.Embedded.1
{

Would it be possible to remove the duplicates from the device list?

Would it be possible to remove the duplicates from the device list?

This issue should be reported to Dell. The iDRAC firmware should not be reporting the same linked device multiple times.

Some Update: I opened a dell case , they are still looking into it.

P.S.: the latest iDRAC Version 6.00.30.00 released on Nov. 11th, still didn't fix the duplicates. The most recent version, where the exporter is working for my servers is iDRAC V5.00.10.20.

I got an Update from my Dell case: They could reproduce the problem and it will be fixed with iDRAC Release 6.10.00.00, which is scheduled for Release in February 2023.

Update: the iDRAC Release 6.10.00.00 is already available and fixed the issue.
