Bear w/ me as I am a newbie :-(
Our HP BL35P blades are equipped w/ SAS controllers.
"lsmod" command on failed client shows:
Module Size Used by
sd_mod 15440 - - Live 0xf8836000
scsi_mod 93796 - - Live 0xf888f000
Does that mean that my disk module got loaded?
Please note, I am using pxe (no floppy/cd to boot from). Which file
should I look into for a kernel module for my hardware?
Also, I am not sure if I follow INSMOD_COMMAND portion of your response.
Would you please elaborate on this as I am not 100% familiar w/ either
Linux or Systemimager.
My /proc/diskstats has some entries in it not nothing related to sda.
/proc/partions is empty.
Thanks for looking into it.
=======================================================================
An 'lsmod' on the client you're trying to image (within BOEL) should
list the module \
for the SCSI/SATA controller if it's recognized.
Check the disk controller in the HP machine you are trying to image. If
the \
Autoinstall CD does not contain a kernel module for the actual hardware
present in \
the machine, disk enumeration won't happen as expected by the Master
script. The \
device identified therein will not be recognized, and cannot be
formatted.
If you have built the client image on one of these blades, be sure that
the modules \
are loaded. You may need to copy the module into the 'my_modules'
directory in the \
initd_template directory and add a line in INSMOD_COMMANDS.
Checking /proc/diskstats and /proc/partitions should yield some
additional clues as \
well. If the device is recognized, it will be present here as sda.
If this is the case, check the .master script and autoinstall.conf and
be sure that \
it is referencing the correct device.
I may not be entirely correct, but I hope this helps.

Subject: Any resolution to "could not stat device /dev/sda" error?
Hi I have posted this a long time ago but have not heard back if there
is a resolution to this.
To recap, I am running system imager version 3.6.3 on my server as well
as client. My server and my client both are HP blade BL35P and I am
trying to deploy a RedHat ES4.0 image. Image capture process gets
completed just fine but when I am ready to deploy this image to my
client (again an hp blade bl35p), it fails w/ the following message:
NO DISK DEVICE FILES WERE FOUND. THIS USUALLY MEANS THE
KERNEL DID NO RECOGNIZE ANY OF THE ATTACHED DISKS.
<snip>
Partitioning /dev/sda...
Old partition table for /dev/sda:
Error: could not stat device /dev/sda - no such file or
directory.
Parted -s -- /dev/sda mklabel msdos || shellout
Error: could not stat device /dev/sda - no such file or
directory.
Killing off running processes.
Please help, I have about 300 systems to build.
Thx
