Bug 112892 – AMD64 2005.1 InstallCD fails to boot on HP Blade BL25p using Insight Manager Virtual Media (UB Module Needed)

• Product: Gentoo Release Media
• Status: RESOLVED FIXED

[Description saffy 2005-11-18 03:05:19 UTC]

When using the Insight Manager Virtual Media to boot a HP BL-25p blade from the
Gentoo AMD64 2005.1 LiveCD you receive an error:-

>> Activating udev
>> Making tmpfs for /newroot
>> No bootable medium found. Waiting for new devices...
!! Could not find CD to boot, something else needed!
>> Loading keymaps
........
>> Keeping default keymap
>> Determining root device...
!! The root block device is unspecified or not detected.
   Please specify a device to boot, or "shell" for a shell...
boot() ::


Going into the shell and checking /dev/ shows no block devices that I recognise
(i.e. no /dev/cdrom, /dev/hda, /dev/sda etc.....)

It turns out the Insight Manager Virtual CD-ROM is an emulated USB CD-ROM.

The INSERT LiveCD (http://www.inside-security.de/INSERT_en.html) does manage to
boot on this system and it uses the UB module (Low Bandwidth USB Block Device?)
to do it. When booting with the INSERT LiveCD the CD appears as /dev/uba.

I have noted that the Gentoo AMD64 2005.1 LiveCD does not have the UB module
enabled.

Please can you include the UB module on the live CD and make the necessary
changes for the LiveCD to recognise /dev/ubx block devices.

Have tried using different combinations of boot switches but problem still
remains (eg. dousb doscsi acpi=on dopcmcia etc.)

Reproducible: Always
Steps to Reproduce:
1. Boot off of LiveCD using Insight Manager Virtual Media
2.
3.

Actual Results:  
>> Determining root device...
!! The root block device is unspecified or not detected.
   Please specify a device to boot, or "shell" for a shell...
boot() ::

Expected Results:  
Find CD-ROM on /dev/uba

Correct.

No.

The low-bandwidth driver is *not* capable of being a module and causes the
normal module to not build.  This is 100% unacceptable.

Try dobladecenter doscsi, please.

dobladecenter doscsi do not make a difference. I have tried the x86 liveCD and
have exactly the same result.

Unfortunately the Virtual CD is the only CD available on these blades :(

The INSERT liveCD will enable me to build a 32-bit Gentoo but fails when I try
to chroot into a 64-bit stage 1 partition.

Is there any other way to install 64-bit Gentoo on this blade??

Thanks

There will be an updated CD hitting the mirrors in a few days.  I would say to
wait and try that one, and if you're still having issues, to report back here.

The main problem is the inability to use the UB driver, but at the same time,
the UB driver does not support anything that the normal driver does not, it is
simply smaller and simpler, mostly for use in memory-constrained situations.

Just downloaded the new AMD64 2005.1-r1 LiveCD and using "doscsi" works!

Great work guys. Many Thanks.
