In order for the HBA to work with the VMware technology, you must replace the native HBA driver, lsi_mr3, with the megaraid_sas HBA driver. If you plan to install the VMware ESXi 5.5 technology on your system after installing the HBA, there are two steps you must perform to use the HBA with the VMware technology. First, prior to replacing the driver, you must change the HBA default cache settings during the VMware technology installation so that the technology installation can complete. Then, after completing the technology installation, you can replace the native HBA driver.
If you already have the VMware technology installed on your system prior to HBA installation, you do not need to change the HBA default cache settings. Instead, go directly to Replacing the Native VMware HBA Driver .
