iPXE discussion forum

I am trying to deploy SPP over the network using EFI, it works when in legacy mode, but soon we will be switching over to EFI. The servers are ML110s, ML350s, DL380s, and more...

The current message that keeps being displayed is:

Code:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

CPU: 0 PID: 1  Comm: swapper/0 Not tainted 3.12.38-44-default #1

SPP is 2016-10

iPXE is compiled from git source on 2017-01-17 build 26050

I also tried chainloading:
syslinux.efi, it crashes.
elilo reports token is too long.
grub2 is unable to get an IP address, and using a static IP is not a reasonable option because more than one server will be running SPP and there is more than one subnet.

the ipxe menu contains:

Code:

There is several posts already about both HP & EFI, as well as EFI and kernels.

Let's hope your issue is simple tho..
first you use kernel and adds some options,
then initrd
and finally you have a imgargs that I think overrides the options you added on the kernel line. You can verify if this is the case with imgstat and comment out boot.

I would suggest that you add all of the arguments to the end of the kernel line, or move down the options of the kernel line down to the imgargs line

I'm getting a new error

so initrd seems to be loaded, you need to try and figure out exactly what it is trying to mount and how that fails.

And i must stress that you are using 3.12 kernel which is pre 3.16 and as such could still have the bug that prevents it from working correctly in regards of loading initrd in EFI mode.

I would start of booting this from pcbios legacy instead of EFI to make sure that the boot succeeds and everything is mounted etc, and after that try to get it running in EFI.

But this is a distribution specific issue, since the kernel is booted you might get better help from HP support, but please do keep us updated on your progress since it can help others.

I looks like my problem for "Unable to mount the file system" was do to testing on a VM (physical servers take too long to boot).
I just needed "initrd=initrd.img" with the rest of the arguments, I now have

Code:

echo Starting ${hpsppver} HPE SPP Interactive Firmware Update

kernel http://${ipserver}/data/hp_spp/${hpsppver}/vmlinuz

initrd http://${ipserver}/data/hp_spp/${hpsppver}/initrd.img

boot

For Automatic/Unattended just change
"TYPE=MANUAL AUTOPOWEROFFONSUCCESS=no AUTOREBOOTONSUCCESS=no"
to
"TYPE=AUTOMATIC AUTOPOWEROFFONSUCCESS=no AUTOREBOOTONSUCCESS=yes"

I am also using the hotfix for 2016.10

Thank you, I understand a little more about how iPXE works.
