SAN filename setting

  san-filename

  # in /etc/dhcpd.conf
  option space ipxe;
  option ipxe-encap-opts code 175 = encapsulate ipxe;
  option ipxe.san-filename code 188 = string;
  
  option ipxe.san-filename "\\efi\\redhat\\grub.efi"

Specifies the filename for the bootloader within a SAN target.

If no SAN filename is explicitly specified, then iPXE will use the appropriate default filename for the platform. For example, on an x86_64 UEFI platform, the default filename will be \EFI\BOOT\BOOTX64.EFI.

Some older operating systems (e.g. RHEL6) will install the bootloader with a non-default filename. You can use either the san-filename setting (or the sanboot --filename option) to specify the correct bootloader filename. For example:

  option ipxe.san-filename "\\efi\\redhat\\grub.efi"
  option root-path "iscsi:192.168.0.1::::iqn.2010-04.org.ipxe.demo:rhel6";
