Enable SSH on ESXi host (VMware ESXi – How to Enable SSH on ESXi host) and check drivers with commnad  esxcfg-scsidevs -a in my case lsi_msgpt3, which is not correct.

To disable lsi_msgpt3 on ESXi 6.5 run:

Download latest mpt3sas driver (currently for ESXi 6.0 U2 – mpt3sas-13.00.00.00-6.0-3755736) from VMware site or for ESXi 6.5 here and unzip it to your desktop. Now you need copy .vib file to your ESXi host to the /tmp folder, easiest way is with WinSCP. After driver installation, about 30 seconds, i restarted ESXi host and it returns to be active.

  • vim-cmd hostsvc/maintenance_mode_enter
  • esxcli software vib install -v „tmp/file.vib“
  • reboot
  • vim-cmd hostsvc/maintenance_mode_exit
