Hello,
first: where should I ask the following question?
We successfully operate some HP Proliant DL380 G3, using Gentoo Xen-kernels
as Dom0 and DomU.
Now i tried to upgrade to Generation 4 and 6:
* HP Proliant DL380 G4
* HP Proliant DL380 G6
Grub works fine. After selecting a kernel to boot, it is loaded and starts
operating and fails some lines later with a kernel panic. The kernel seems
not to find the HP SCSI controller (/dev/cciss/...).
I made sure, that the kernel has build in the needed drivers as described
here:
http://en.gentoo-wiki.com/wiki/HP_ProLiant_DL380_G5
Funny is, that the Gentoo boot images do work, for example
install-x86-minimal-20100216.iso.
I use the iso images to boot the system initially, initialize the SCSI disks
with fdsik and mkfs... and then mount the SCSI drives (/dev/cciss/...), copy
a working tarball-image, populate the filsystem and then use the grub shell
make it bootable.
Attached is a screen shot with the error message.
Is this screenshot from a domU or dom0 ? If it's from a domU then I
think that in Xen you have a different driver than cciss for the
disks.
If it's from a dom0, are you sure that you have the cciss driver
built-in instead of a module ? From the screenshot it seems that it's
not present at the point the kernel is booting.
It is the screenshot of the Dom0. And yes - also for me the driver seems
not to be available during boot time. But i am sure to have it build in.
And on older hardware (G3 - generation 3 HP hardware) the same kernel
seems to work, mounting the cciss devices.
Here is what mount says in the same kernel on a G3 hardware (sorry for
the linebreaks):
----
orion ~ # mount
/dev/cciss/c0d0p1 on / type ext3 (rw,noatime)
proc on /proc type proc (rw,nosuid,nodev,noexec)

usbfs on /proc/bus/usb type usbfs (rw,noexec,nosuid,devmode=0664,devgid=85)

Should I try to fix the Xen-Kernel from Gentoo with some HP driver
source code? Or could it be a completly other issue?
