Wondering if anyone can shed any light on the requirements for ESXi v5.1 upgrade.
I understand /boot needs to be a minimum of 1GB in size,
but I cannot find any easy way of determining how large /boot is on my existing 5.0 servers.
I ran a console session and checked out 'df -u' (?) and similar but couldn't make much headway.
I can see all my SAN LUNs okay and some local disk objects, but nothing showing /boot as a name.
My hosts were originally configured identically back at version ESXi 4.0,
then were upgraded to v4.1 and then last year up to v5.0 U1.
