Cisco M3 C220 VMware ESX v6.5 upgrade to 7.0 and notes

 Upgraded a Cisco M3 C220 from ESXi v6.5 to v7.0 and had some bumps along the way.

Here are two sites that I got some information from that I wish I had found earlier.

This particular machine had the Cisco customized version of v6.5 installed.  During the install of v7.0 several drivers had to be removed. Something that I wished I had known about earlier was to use the "--ok-to-remove" to have VMWare automatically VIB's it doesn't like; this would have saved a bunch of time!

Error message: 'Could not find a trusted signer.'

Workaround: esxcli software acceptance set --level=CommunitySupported

and tack on "--no-sig-check" at the tail end of the esxcli software line

Error Message: '[Errno 28] No space left on device'

Workaround: Make sure a datastore has been selected for swapfile space

Typing in: "/sbin/reboot" will reboot a host if no VM's are currently running.

If that doesn't work, try downloading the patch do a datastore and run the patch from there.  IE: 

esxcli software profile update -p ESXi-6.7.0-20210301001s-standard -d /vmfs/volumes/300gbRAID1/ESXi670-202103001.zip
