and one additional question:
i initially installed esxi with the hpe custom image VMware-ESXi-6.0.0-Update3-5050593-HPE-600.9.7.0.17-Feb2017.iso . later, i updated esxi with VMware-ESXi-6.0.0-Update3-6765062-HPE-600.10.1.5.19-Oct2017.iso . then, i did patches with vcenter update manager from time to time (only the default baselines, critical and non critical). so taday it shows build 9239799 .
question: do i have to use the VMware-ESXi-6.0.0-Update3-6765062-HPE-600.10.1.5.19-Oct2017.iso for my new installation and then update via update manager to get to build 9239799 or can i use this image: VMware-ESXi-6.0.0-Update3-7967664-HPE-preGen9-600.9.8.0.7-Jun2018.iso (last pre gen9 custom inage) from here:
and a 2nd additinal question (as i have forgotten):
shall i just diskpart /clean the sd-card (so i have just unallocated space on the sd card) before esxi installation or shall i diskpart /clean, create partition primary, active, format fs=fat 32 quick?
maybe this was my mistake the first time: that i created a partiton on the sd card that remained alongside with the esxi installation.
