ESXi 6.5 on PowerEdge R420 with RAID 1 PERC S110

Hi, guys. I need to install an ESXi 6.5 on a PowerEdge R420 server with RAID 1. The PERC is the S110. I've already configured RAID 1 with two 1.8TB disks. When I run the installer and it asks where to install, the installer recognizes both disks and not the only one virtual disk in RAID 1. It's strange but ok, the installer runs. After that, when try to boot the ESXi system, it show the RAID 1 is degraded and the there is no ESXi installation. Do I have to customize my ISO with the PERC S110 driver to make it work? Or it wouldn't work for this PERC? Thanks in advance.
