ESXi 6.5 upgrade failed

Today i was trying to upgrade our esxi 6.0 (running on DELL poweredge) to esxi 6.5. Upgrade did not start and throwing conflicts vib error.

Below is the screenshot of error which i was receiving.

  After checking VMWare documentation i found ‘mpt3sas’ driver which enables support for AVAGO MPT Fusion based SAS3 (SAS 12.0 Gb/s) Controller(s). Dell don’t support this device and hence this driver can be safely removed.

  so i opened ssh session to esxi host and removed conflicting vib using below command.

esxcli software vib remove -n scsi-mpt3sas


 Got below message post removal.

rebooted the ESXi host and then tried to upgrade it. It completed successfully.
