When DMP is enabled for native devices, the dmp_native_support tunable is set to ON. When the tunable is ON, all DMP disks are available for native volumes except:
Devices that have a VxVM label
If you initialize a disk for VxVM use, then the native multi-pathing feature is automatically disabled for the disk.
You can use the disks for native multi-pathing if you remove them from VxVM use.
Devices that are multi-pathed with Third-party drivers
If a disk is already multi-pathed with a third-party driver (TPD), DMP does not manage the devices unless TPD support is removed.
To display whether DMP is enabled
dmp_native_support.# vxdmpadm gettune dmp_native_support
Tunable Current Value Default Value ------------------ ------------- ------------- dmp_native_support on off
dmp_native_support tunable is ON, use the vxdisk list command to display available disks. Disks available to LVM display with the TYPE auto:none. Disks that are already in use by LVM display with the TYPE auto:LVM.
