iPXE Sanboot command hangs :(

[Gavin Williams]

Afternoon all,

I've posted this to the iPXE forums aswell, but thought might be worth posting it here to see if anybody has any ideas...

Anyhow, the problem at hand is that the 'sanboot' command consistently hangs on our HP BL460c G7 blades... This means that any reboots etc need to manually bypass razor to get back into the OS...

I've tried a few different bits today, but am struggling to get it working at-all...

There doesn't appear to be a 'DEBUG=' option for sanboot, so can't enable that.

Any ideas???

Cheers
Gavin

Afternoon all

I went and posted this issue on the ipxe-developers mailing list (http://lists.ipxe.org/pipermail/ipxe-devel/2013-January/002141.html), and got a very useful response from Andrew Bobulsky, linking me to: http://ipxe.org/appnote/work_around_bios_halting_on_ipxe_exit

So looks like it's a recently identified issue with iPXE.
I've tried the work-around, by install Apache HTTPD on my pxe server, and stuck grub.exe on there.
Then changed boot_local.erb as follows:

diff --git a/lib/project_razor/model/redhat/6/boot_local.erb b/lib/project_razor/model/redhat/6/boot_local.erb
index 5c76e0b..fb1f378 100644
--- a/lib/project_razor/model/redhat/6/boot_local.erb
+++ b/lib/project_razor/model/redhat/6/boot_local.erb
@@ -6,4 +6,4 @@ echo Active Model node state: <%= @current_state %>
 echo Continuing local boot

 sleep 3
-sanboot --no-describe --drive 0x80
+chain http://<%= config.image_svc_host %>/grub.exe --config-file="rootnoverify (hd0);chainloader +1"

 
Feels a bit hacky atm, but it's got me going...

Am guna see if there's any way I can assist iPXE developers in getting sanboot working in my env, but in the meantime, if anyone else has the same issue the above may well get you working :)

Cheers for the suggestion.
Might give it a go when I can spare 15mins...

You might have luck with DEBUG=sanboot_cmd

You can add debugging to any .c file in iPXE by using its source filename without extension.

Cheers for the suggestion.

Will give that a go and see what it does... Will be a bit easier than hosting a grubboot image...

Hi, Gavin

I am using HP DL360Gen8 server, also sanboot --no-describe --drive 0x80 does not lead to local disk boot.

My workaround is to replace this sanboot command with "exit", also add "exit" line in ipxe.razor. So that system go back to next device in the BIOS boot order.

Cool, so it looks like a double exit works :)

To confirm:
edit boot_local.erb, replace sanboot command with 'exit'.
edit razor.ipxe, add an exit command between chain and :error.

Thank you very much for testing this.

I am inclined to make this change, so if anyone else wants to test it
and report any problems that they encounter, that would be great.
