In the process of upgrading a vSAN ReadyNode cluster from ESXi 6.5 to 6.7 a warning appeared in the vSAN Health check. The first host in the cluster had gone through the upgrade and was now showing the warning “Controller driver is VMware certified” (Note 1 in the image below, click on it for a larger view). The Dell HBA330 card was using an older version of the driver (2 in the image below) than recommended (3).
All workloads were still online, but running VMware Update Manager (VUM) did not clear this warning. Looking in the VUM patch listing showed the driver for ESXi 6.5 (4) but not the version recommended for 6.7.
It was necessary to manually load these replacement drivers in. A quick google showed they could be sourced from VMware’s download site. Extract the ZIP file from the download and then use the “Upload from File” option in VUM (5) to upload the ZIP file which was inside (in this case “VMW-ESX-6.7.0-lsi_msgpt3-17.00.01.00-offline_bundle-9702440.zip“). The new driver should then appear in the list (6) and will automatically be added to the “Non-Critical Host Patches” baseline (7). Final remediation is now just a case of applying that updating baseline to the host.
In this particular instance the hosts were Dell PowerEdge R630 vSAN ReadyNodes with the HBA330 SAS HBA Controller option but the principles outlined in this post should apply to other configurations with the same symptoms.
