1) Download the ESXi MFTs for your version (
5.5 link |
6.0 link - Both from
here)
2) Upload the mft .vib file and the firmware .bin to your host using whatever method you want. (I'm partial to dumping it in a datastore, then moving it to /var/tmp.)
3) SSH into your ESXi host and install the mft:
esxcli software vib install -v /var/tmp/mft-3.8.0.56-10EM-600.0.0.2295424.x86_64.vib
4) Reboot
5) Update the firmware:
/opt/mellanox/bin/flint -allow_psid_change -d mt26428_pciconf0 -i /var/tmp/MHQH29B-2.10.720.bin burn
6) Reboot again
