In case getting following error while starting kdump service
Memory for crashkernel is not reserved
Please reserve memory by passing "crashkernel=X@Y" parameter to the kernel
If your server is having more than 4GB of RAM then crashkernel=auto (in /etc/grub.conf line starting with kernel)will automatically Reserve memory else need to specify in following format:
crashkernel=0M-2G:128M,2G-6G:256M
NOTE : - Find attachment
If physical memory is 0MB to 2GB then 128MB of memory will be reserved
If physical memory is 2MB to 6GB then 256MB of memory will be reserved
Now REBOOT server for kdump changes to take effect (1st time after kdump installed, a new INITRD will be generated)
Thats it!!!
