Not quite right. If you do: # rpm -qpl kernel-debuginfo-2.4.21-40.EL.i686.rpm | grep vmlinux you'll see: /usr/lib/debug/boot/vmlinux-2.4.21-40.EL.debug /usr/lib/debug/boot/vmlinux-2.4.21-40.ELhugemem.debug /usr/lib/debug/boot/vmlinux-2.4.21-40.ELsmp.debug You, of course, want the smp version. I'm assuming you want to examine the core file with crash. If so, something like the following should work: crash /usr/lib/debug/boot/vmlinux-2.4.21-40.ELsmp.debug /path/to/vmcore > Can anyone give me the link to the rpm i am looking for , or suggest some > idea. ( the server that i am dumping vmcore is version 5 ) You mean the netdump server is running on a RHEL 5 system? That is fine. > I have bunch of server with version 2 and version 3 and version 4 in my > production environment for which i have to configure netdump to collect the > vmcore in version 5 server . Right, running the netdump server on a RHEL 5 system is fine. You should have no problems collecting vmcores from your AS 2.1, RHEL 3 and RHEL 4 systems.
