Installation

Minimal HW/VM Requirements

  • 4GB RAM
  • 33GB Disk

Network Installation

The machine you want to install needs to be registered in sysdb. If you don't have the bob command installed locally you can login to lxsup.psi.ch to use it. Remember that you need a valid Kerberos ticket before modifying a sysdb entry via bob. More details regaring bob can be found here.

Optional you can set netboot and RHEL 8 installer but that can also be selected manually in be boot menu:

bob node netboot $FQDN
bob node set-attr $FQDN ipxe_installer=rhel8install

Installation with UEFI

Start the machine and select network boot (if not already the default), then you get following menu:
Grub default menu

There select "Install Red Hat Enterprise Linux 8.7" Grub menu selection for iPXE

NOTE: After the installation the boot order will be changed to localboot again! So if you reinstall make sure that you re-set the bootorder via the efi menu or the commandline: https://linux.die.net/man/8/efibootmgr

[root@lx-test-02 ~]# efibootmgr
BootCurrent: 0004
BootOrder: 0004,0002,0000,0001,0003
Boot0000* EFI Virtual disk (0.0)
Boot0001* EFI VMware Virtual SATA CDROM Drive (0.0)
Boot0002* EFI Network
Boot0003* EFI Internal Shell (Unsupported option)
Boot0004* Red Hat Enterprise Linux

[root@lx-test-02 ~]# efibootmgr --bootorder 2,4,0,1,3

(there is no need to have the leading 000 )

Installation with Legacy BIOS

Start the machine and select network boot (if not already the default), then you get following menu, where the default depends on the sysdb configuration, but you may override it manualy:

select RHEL 8 installation
