"Status of other host hardware objects" on HPE Gen10 servers

Problem
On HPE Gen10 servers we have observed several error messages in hardware monitoring and VMware vCenter reports these as a critical problem.

Device IO Module 4 NIC_Link_01P4
This problem has been reported on both vSphere 6.5 and 6.7.

Solution
It turned out that the servers that had this problem were using ILO version 1.30 and 1.35 while the servers that did not have this problem were using ILO 1.20. After downgrading ILO to version 1.20 the problem was resolved. Hopefully this will be fixed in a future version.


Downgrading ILO is a new feature of ILO 5:
The components can be organized in to install sets and can be used to rollback/Patch faulty firmware
Note that while you can upgrade ILO directly with the Update Firmware functionality, you can't downgrade it the same way. In order to be able to downgrade ILO you must upload it to the ILO Repository first. Once it has been uploaded you can downgrade the ILO firmware.







After having downgraded ILO you will need to go into each of the ESXi host's hardware status and press the reset sensors button and everything will be fine.
