How do you completely disable dm-multipathing in Centos 6 for SAN booted host.
In Centos 5, I would: Edit /etc/fstab to on reference a single path of the device ie: /dev/mapper/mpath0a / ..... to /dev/sda / ... Edit /boot/grub/grub.conf to reference a single device path # chkconfig multipathd off In addition, make sure the /etc/sysconfig/mkinitrd/multipath file has the following line: MULTIPATH=NO Edit /etc/multipath.conf to be: # Blacklist all devices by default. Remove this to enable multipathing # on the default devices. blacklist { devnode "*" } mkinitrd -f /boot/initrd-`uname -r`.img `uname -r` What are the equivalent steps in Centos 6 -- Matt |

You could edit /boot/grub/grub.conf and add nompath and perhaps nodmraid to the kernel line.

The solution:
a. service multipathd stop b. chkconfig multipathd off c. remove the multipath module and rebuild the initrd. dracut -o "multipath" no-multipath.img boot from the new initrd. In this case it is no-multipath.img d.Add the boot parameter rdblacklist=multipath |
