grub.conf文件中有关内核参数的问题

夏织风

我借此机会先给各位大神们拜个晚年！祝大家新年万事如意！
此为我的grub.conf文件中的信息：
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/mapper/vg_kzoubt-lv_root
#          initrd /initrd-[generic-]version.img
#boot=/dev/sda
default=0

        root (hd0,0)
        kernel /vmlinuz-2.6.32-431.23.3.1.ky3.1.x86_64 ro root=/dev/mapper/vg_kzoubt-lv_root rd_LVM_LV=vg_kzoubt/lv_swap rd_NO_LUKS rd_NO_MD rd_LVM_LV=vg_kzoubt/lv_root SYSFONT=latarcyrheb-sun16 LANG=zh_CN.UTF-8 vga=0x314  KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet
        initrd /initramfs-2.6.32-431.23.3.1.ky3.1.x86_64.img

请问各位大神如下内核参数代表的是什么意思：
rd_LVM_LV=vg_kzoubt/lv_swap
rd_NO_LUKS
rd_NO_MD
rd_LVM_LV=vg_kzoubt/lv_root
rd_NO_DM

这些内核参数和Kdump有关系吗？
万分感谢！
