VMware HP ESXi 5.5 U2 Upgrade Error (Unequal Payload Attributes Mellanox_bootbank_net-mst)

Summary
The upgrade stalls on Scanning system…. Gathering additional system information. This may take a few moments.
On the background screen: ValueError: Cannot merge VIBs Mellanox_bootbank_net-mst_2.0.0.0-1OEM.550.0.0.472560, Mellanox_bootbank_net-mst_2.0.0.0-1OEM.550.0.0.472560 with unequal payloads attributes ([net-mst: 8.250 KB], [net-mst: 8.242 KB])

Upgrade_HPESXi5.5U2

To Fix:
1. Login to ESXi via SSH
2. Check All VIBs:
~# esxcli software vib list

Check All VIBs with net in name
~# esxcli software vib list | grep net

List Network Uplinks Installed on Server (Check that Mellanox is not used by any of uplinks)
~# esxcli network nic list

Remove net-mst VIB/offline bundle driver
~# esxcli software vib remove -n net-mst
You should receive the following confirmation after you run the above command:
Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.
VIBs Removed: Mellanox_bootbank_net-mst_2.0.0.0-1OEM.550.0.0.472560

3. Restart host
4. Boot to HP Custom ESXi Installation Image/CD
The Installation should not give error now

Thanks. I had this problem this weekend and didn’t know how to verify that I wasn’t using the VIB that failed.
