PXE network boot

BIOS

Please note, if you create an image from a legacy BIOS, it can only be started by this type of hardware; UEFI ditto. so create a LUN per BIOS mode.

Boot from media until installer starts.

F2 for console

iscsiadm -m discovery -t st -p <host>

Find the right target on:

Connect

iscsiadm -m node --targetname <target> --portal <host:3260> --login

Disconnect

iscsiadm -m node --targetname <target> --portal <host:3260> --logout

type [Q][H]! exit[Q] to return to the installation shell.

After this, go through the setup and install the OS to the linked ISCSI LUN.

After installation, return to the shell with F2

exit

Reboot

PXE boot

Boot the volume via pxe, configure the following items per "node" (if you are going to clone the lun of course)

Configuration can be done by booting live media on the node, and then adjusting the configurations.

Change GRUB to new lun → target and initiator name

Mount new iscsi lun via a working Linux installation

Change hostname (can be done after booting)

extra

Check mounted volume

fdisk -l

Note het diskid /dev/sd<>

mkdir /mnt/iscsitarget mount /dev/sd<> /mnt/iscsitarget
