When Dynamic Multi-Pathing (DMP) is installed on linux, Native device support is enabled by default for non-root devices.

To enable root support in DMP, the following command can be used:

NOTE: A reboot will be required.


/sbin/vxdmpadm settune dmp_native_support=on

As part of enabling root device support, this command will update the grub configuration with a new entry (Title: vxdmp_root) which allows the system to boot off a root device managed by DMP. This entry will be the default boot option.



node#1 vxdmpadm settune dmp_native_support=on
VxVM vxdmpadm INFO V-5-1-15866 DMP Native Support is enabled/disabled for root LVM volume. Please reboot the system for changes to take effect.
