ILO V2 using CLI to mount and boot from HTTP ISO

ranck42 — Fri, 06 Feb 2015 17:22:11 GMT

I am trying to mount and boot from a Red Hat ISO that I have put on a web server. Because I am working remotely in a secured environment I do no have web interface access to the ILO only command line. So here is what I have:

</>hpiLO-> oemhp_ping /map1 *.*.*.199
status=0
status_tag=COMMAND COMPLETED

</>hpiLO-> set /map1/oemhp_vm1/cddr1 oemhp_image=http://*.*.*.199/var/www/html/rhel-server-6.6-x86_64-dvd.iso
status=0
status_tag=COMMAND COMPLETED

</>hpiLO-> show /map1/oemhp_vm1/cddr1 -a
status=0
status_tag=COMMAND COMPLETED

/map1/oemhp_vm1/cddr1
Targets
Properties
oemhp_image=http://*.*.*.199/var/www/html/rhel-server-6.6-x86_64-dvd.iso
oemhp_connect=No
oemhp_boot=No_Boot
oemhp_wp=Yes
oemhp_applet_connected=No
Verbs
cd version exit show set

</>hpiLO-> set /map1/oemhp_vm1/cddr1 oemhp_boot=Once
status=0
status_tag=COMMAND COMPLETED

</>hpiLO-> show /map1/oemhp_vm1/cddr1
status=0
status_tag=COMMAND COMPLETED

/map1/oemhp_vm1/cddr1
Targets
Properties
oemhp_image=http://*.*.*.199/var/www/html/rhel-server-6.6-x86_64-dvd.iso
oemhp_connect=No
oemhp_boot=Once
oemhp_wp=Yes
oemhp_applet_connected=No
Verbs
cd version exit show set

</>hpiLO-> show /system1/bootconfig1/bootsource1 -a
status=0
status_tag=COMMAND COMPLETED

/system1/bootconfig1/bootsource1
Targets
Properties
bootorder=1
Verbs
cd version exit show set

So, when I do a "reset hard" the system goes through a bootup, but it boots to the already installed OS on the hard drive, not from the ISO that I'm trying to use to install a new OS.

Any idea what I'm doing wrong here? Please excuse the obscured IPs, but again, it's a secure environment and I'm not supposed to let those get out. They do match.

So, I sorted out the problem getting the server to boot from the ISO image. I needed to not specify the path to the web root, and also put the file one directory level down from there. So, now it boots from ISO, but I ran into another roadblock.

Now I seem to have a problem with console display. Using VSP I get this far:

Loading vmlinuz......
Loading initrd.img....................................ready.
Probing EDD (edd=off to disable)... ok
ÿÿ

I've seen this before with some other systems, but I'm not sure of a work-around.

When I use TEXTCONS I get a message saying:
Monitor is in graphics mode or an unsupported text mode.
Monitor is in graphics mode or an unsupported text mode.
Monitor is in graphics mode or an unsupported text mode.

Any thoughts on how to get around this?

you need to disable frame buffer. on your boot line append 'vga=normal nofb'

What boot line would that be? I don't have a boot line that I know off. I get the following:

- Press the <ENTER> key to begin the installation process.

And eventually, it continues whether I press <ENTER> or not.

I tried entering "linux text" at that prompt, but that didn't seem to work.

try hitting <esc> and see if it will give you a boot prompt. then you'd type linux vga=normal nofb and could even add the text option
