actually the kernel for crash dumps. However, dumping may not be successful
under any circumstances. For example, when the transition table suspension is
interrupted, a critical kernel fault occurs, or a storage fault occurs during system
breakdown, you need to obtain the location information using other methods.
10.1.2 Configuring Kdump on RHEL
1. Prerequisites
To dump the vmcore file to the network storage, you need to access an external
server via NFS or SSH. The free space of the dump target (local or remote) must be
large enough to receive the vmcore file.
To configure kdump in the Xen kernel, you need to install a common kernel of the
same version as the current Xen kernel.
 On a 32-bit system with a memory more than 4 GB, you need to install a PAE
kernel of the same version as the current Xen kernel rather than a common
kernel.
 You only need to install the PAE kernel and still boot with Xen. No reboot is
needed after the kernel installation.
To install the kdump toolkit:
1. Check whether the kexec-tools is installed by executing the #rpm -q kexec-
tools command.
2. If the kexec-tools is not installed, execute the #yum install kexec-tools
command.
You can choose automation script configuration or manual configuration.
2. Automation Script Configuration
Obtain the script through Kdump Helper.
