After installing sles11 sp2 on an HP DL380 the following error is displayed during boot on several servers:

facts:

the server was running sles11 sp1 for over a year before, no problems

the same boot problem on a handfull of similar servers

but 30+ servers also installed with sp2 (and sp1 before) do not show this problem

all our servers boot from SAN (EMC DMX/VMAX)

the problematic sp2-servers all have at least 4 SAN-volumes, where as the working sp2-servers usually have one boot and one data volume

Has any one ever had the same or a similar problem or behaviour? and what could be the cause or the cure?

Hi
On the updated servers affected, have all had the latest updates esp the
kernel?

On a side note, when pasting console text, can you use code tags :wink:

Hi Malcom,

we did some more investigation:

  1. if we set the kernel option maxcpus=1, the system installs and boots correctly
  2. after that, we install the latest updates, ie. uname -a shows
    Linux lx00142 3.0.34-0.7-default #1 SMP Tue Jun 19 09:56:30 UTC 2012 (fbfc70c) x86_64 x86_64 x86_64 GNU/Linux
  3. next we reboot the system without the maxcpu-option (=all cores/threads on)
    and the system hangs again with same problem

thanks,
Vincent

oops, “uname -a” from wrong system :-), nevertheless:
lx00241:~ # uname -a
Linux lx00241 3.0.34-0.7-default #1 SMP Tue Jun 19 09:56:30 UTC 2012 (fbfc70c) x86_64 x86_64 x86_64 GNU/Linux

Hi
Sounds like you might need to try some other grub boot options (there
are many), is there a later BIOS for the system available?

Can you try the following grub boot option;

acpi_osi=Linux
