Why there are two entries for crashkernel parameter in the grub.conf file?












0















I'm trying to enable kdump on a server but in the grub configuration file, there are two entries for the crashkernel parameter for each OS entry. I know that this parameter is used to allocate memory to the crash kernel. I'm trying to understand what is the significance of having two entries for the crashkernel parameter in grub.conf.



Here's a screenshot of grub.conf
