sles11sp1 dump is not captured

I setup kdump on sles11sp1, on issuing “echo c > /proc/sysrq-trigger” capture kernel is not booted and kernel dump is not created.

Here is my system configuration:

Welcome to SUSE Linux Enterprise Server 11 SP1 (x86_64) - Kernel \r (\l).

blade797:~ # uname -a
Linux blade797 #1 SMP 2010-05-20 11:14:20 +0200 x86_64 x86_64 x86_64 GNU/Linux

blade797:~ # cat /proc/cmdline
root=/dev/disk/by-id/cciss-3600508b1001030343220202020200018-part2 resume=/dev/disk/by-id/cciss-3600508b1001030343220202020200018-part1 splash=silent crashkernel=256M-:128M vga=0x317

steps followed to enable kdump:

  1. yast2 kdump
  2. chkconfig boot.kdump on
  3. reboot
  4. cat /sys/kernel/kexec_crash_loaded
  5. echo c > /proc/sysrq-trigger
  6. system panicked, but dump is not captured.
  7. I´m missing /proc/vmcore on Sless11Sp1. Does anybody have any idea?

any help is appreciated, thanks in advance.

I’ve just moved that topic here from German Talk.

I kind of think the OP would be best helped on a SLES forum SUSE Linux Enterprise Server (SLES), we will try here, but SLES is not openSUSE.
