Hello all,

Today, I’ll show you how to know which driver and version we are using in our ESXs.

  1. Connect to the ESXi using SSH.
  2. Run the following command to understand which driver host is using.

  3. In our case, the host is using megaraid_perc9. This driver is not supported, so we need to disable it and enable the right one lsi_mr3. To understand which driver hosts should use, I kindly recommend (from time-to-time)  to check the vSAN adapter VMware Compatibility Guide.
  4. Reboot the host with “Ensure Accesibility” to avoid vSAN Resyn. When the host is back in the vCenter, run the following command to see which driver viersion host is using.
  5. Now, host is using lsi_mr3, which is approved in the VMware Compatibility Guide.
  6. The following command shows the parameters the driver is configured.

Sharing is caring!
