The dmp_native_support tunable is persistent across reboots and product upgrades. You can disable native support for an individual device if you initialize it for VxVM, or if you set up TPD multi-pathing for that device.

To remove support for native devices from all DMP devices, turn off the dmp_native_support tunable.

To turn off the dmp_native support tunable:

# vxdmpadm settune dmp_native_support=off

To view the value of the dmp_native_support tunable:

# vxdmpadm gettune dmp_native_support
