ESXi 6.0 to 6.5 upgrade - Conflicting VIBs in HP image

Upgrading HP 6.0 Image to 6.5 is listed as incompatible in VUM due to below VIB Conflicts

The upgrade contains the following set of conflicting VIBs:
Emulex_bootbank_scsi-lpfc820_8.2.4.151.65-1OEM.500.0.0.472560
Emulex_bootbank_scsi-lpfc820_8.2.4.151.65-1OEM.500.0.0.472560

Remove the conflicting VIBs or use Image Builder to create a custom upgrade ISO image that contains the newer versions of the conflicting VIBs, and try to upgrade again.

Fix

1) Look for the drivers first

[root@esx01:~] esxcli software vib list | grep  lpfc
lpfc                           11.4.199.0-1OEM.600.0.0.2768847        EMU              VMwareCertified   2018-06-01
scsi-lpfc820                   8.2.4.151.65-1OEM.500.0.0.472560       Emulex           VMwareCertified   2017-09-25

So I have ipfc and scsi-lpfc820 drivers installed. 

2) Check if it is in use

[root@esx01:~] esxcli network nic list

Highlighted are the drivers in use and that confirmed scsi-lpfc820 is not in use. 

3) Remove the conflicting VIB
[root@esx01:~] esxcli software vib remove -n scsi-lpfc820

Removal Result
   Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.
   Reboot Required: true
   VIBs Installed:
   VIBs Removed: Emulex_bootbank_scsi-lpfc820_8.2.4.151.65-1OEM.500.0.0.472560
   VIBs Skipped:

4) Reboot ESXi host

5) Scan again and check status on VUM status

This time it shows Non-Compliant! 

So I decided to try removing Mellenox driver, which used to give issues with ESX5x to 6 upgrade! 

[root@esx01:~] esxcli software vib list |grep Mellanox

net-mlx4-core                  1.9.9.4-1OEM.550.0.0.1331820           Mellanox         VMwareCertified   2017-09-25

[root@esx01:~] esxcli software vib remove -n net-mlx4-en

Rebooted ESXi host again. 

Once it came back, scanned again with VUM and checked status. It was happy this time and I could update it without issues.

Thank you!
