From 84d406ccf48c8808b0bb30d526b758e4b58cacc8 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Wed, 12 Apr 2017 15:03:25 +0100 Subject: [block] Allow use of a non-default EFI SAN boot filename Some older operating systems (e.g. RHEL6) use a non-default filename on the root disk and rely on setting an EFI variable to point to the bootloader. This does not work when performing a SAN boot on a machine where the EFI variable is not present. Fix by allowing a non-default filename to be specified via the "sanboot --filename" option or the "san-filename" setting. For example: sanboot --filename \efi\redhat\grub.efi \ iscsi:192.168.0.1::::iqn.2010-04.org.ipxe.demo:rhel6 or option ipxe.san-filename code 188 = string; option ipxe.san-filename "\\efi\\redhat\\grub.efi"; option root-path "iscsi:192.168.0.1::::iqn.2010-04.org.ipxe.demo:rhel6"; Originally-implemented-by: Vishvananda Ishaya Abrams Signed-off-by: Michael Brown --- src/core/null_sanboot.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/core/null_sanboot.c') diff --git a/src/core/null_sanboot.c b/src/core/null_sanboot.c index b09562e28..7c0680f58 100644 --- a/src/core/null_sanboot.c +++ b/src/core/null_sanboot.c @@ -37,7 +37,8 @@ static void null_san_unhook ( unsigned int drive __unused ) { /* Do nothing */ } -static int null_san_boot ( unsigned int drive __unused ) { +static int null_san_boot ( unsigned int drive __unused, + const char *filename __unused ) { return -EOPNOTSUPP; } -- cgit v1.2.3-55-g7522
