Enabling DMP support for native devices
Dynamic Multi-Pathing (DMP) is a component of SF. DMP supports Veritas Volume Manager (VxVM) volumes on DMP metadevices, and Veritas File System (VxFS) file systems on those volumes.
DMP can also provide multi-pathing functionality for the native operating system volumes and file systems on DMP devices.
For more information on using DMP with native devices, see the Dynamic Multi-Pathing Administrator's Guide.
After you install SF for the first time, use the following procedure to enable DMP support for native devices.
If DMP native support for native devices is enabled on a system before you upgrade SF, DMP native support is maintained when SF is upgraded.
Starting with Solaris 11.1, enabling DMP support for native devices also enables support for ZFS root on DMP devices. If DMP native support is enabled with an earlier Solaris version, ZFS root devices are not supported on DMP. Upgrading the operating system to version 11.1 or later does not enable support for ZFS root devices by default. To enable DMP support for the ZFS root devices, use the following procedure to enable DMP support for native devices again.
To enable DMP support for native devices
- Turn on the tunable parameter to enable DMP support:
# vxdmpadm settune dmp_native_support=on
The dmp_native_support parameter is persistent.
- If the system has Solaris version 11.1 or later installed, turning on DMP support also enables support for the ZFS root device. Reboot the system for the changes to take effect.
