@foglalt no the pending Mac is not the issue. It looks up pending macs based on a 1 on the pending.
The issue, it seems, is a primary Mac is changing for a host. The primary should move to additional macs and the new primary should become primary. However the move is probably happening before setting the new primary Mac causing fog to think the host is no longer valid.
ESXi 6.5u1
NOTE: This guidance only supports network booting of the uefi installer for ESXi. The reason for this is the fog project does not ship iPXE kernels that support the comboot function. If you want to boot your ESXi server in legacy mode you will need to compile your own specific version of undionly.kpxe to add in the IMG_COMBOOT.
First we’ll create the required directories:
mkdir /images/os/esxi
mkdir /images/os/esxi/6.5u1
Now we’ll mount the ESXi installer iso over the loop directory. Then we’ll copy the contents of the DVD to the directory we built above.
mount -o loop -t iso9660 /{full path where you have the iso stored}/VMware-VMvisor-Installer-6.5.0.update01-5969303.x86_64.iso /mnt/loop
cp -R /mnt/loop/* /images/os/esxi/6.5u1
umount /mnt/loop
Edit the boot configuration file to use NFS to access all of ESXi’s files.
# remove forward slashes from the config file
sed -i 's/\///g' /images/os/esxi/6.5u1/efi/boot/boot.cfg
Now we need to edit the/images/os/esxi/6.5u1/efi/boot/boot.cfg file to insert the prefix parameter. Insert the following line just below the title parameter. Also, be sure to replace {fog_server_ip} with the actual IP address of your fog server.
prefix=nfs://{fog_server_ip}:/images/os/esxi/6.5u1
The last bit of magic we need to do is setup a new FOG iPXE boot menu entry for this OS.
In the fog WebGUI go to FOG Configuration->iPXE New Menu Entry
Set the following fields
Menu Item: os.esxi65u1
Description: ESXi 6.5u1 Installer
Parameters:
kernel nfs://${fog-ip}:/images/os/esxi/6.5u1/efi/boot/bootx64.efi -c nfs://${fog-ip}:/images/os/esxi/6.5u1/efi/boot/boot.cfg
boot || goto MENU
Menu Show with: All Hosts
That’s it, just pxe boot your target system and pick ESXi 6.5u1 Installer from the FOG iPXE boot menu.
If for some reason you can not use NFS to pxe boot into the ESXi installer you can use tftp or http. If you want to use tftp extract the ESXi install files to /tftpboot/os/esxi/6.5u1. Then update the nfs:// protocols to tftp:// Be sure to remove the ':/images' after the host name or you will have errors. (i.e. kernel nfs://${fog-ip}:/images/os/esxi would become kernel tftp://${fog-ip}/os/esxi)
