Before changing the configuration, ensure that the partition on which /var resides has
enough disk space for the vmcore file. This is necessary because kdump stores kernel
core dumps under /var, and the vmcore file is approximately the size of the physical
memory of the system. You can change the location of the vmcore file by setting the
KDUMP_SAVEDIR
parameter in the /etc/sysconfig/kdump file.
Perform the following procedure as the root user:
1. Verify that the kernel-kdump and kexec-tools packages are installed by typing the
following commands:
rpm -q kernel-kdump
rpm -q kexec-tools
rpm –q kdump
2. If the kernel-kdump or kexec-tools packages need to be installed, type either or
both of the following commands as needed:
yast2 -i kernel-kdump
yast2 -i kexec-tools
yast2 –i kdump
