PowerPath and VxVM Co-existense

In order to use Powerpath Pseudo devices in Solaris running Veritas Volume manager, one need to run the "powervxvm" utility. Both native and pseudo device names will be visible to VxVM and in the vxdisk list output.

* To avoid confusion, we can remove the native devices from view using "vxdiskadm"

* "vxprint" shows the type of device used.

Veritas Volume manager CDS disk group type is not supported with Powerpath pseudo devices.

VxVM 4.1 introduced TPD ( Third party driver ) ASL for automatically recognizing Powerpath pseudo devices. VxVM 4.1 uses Powerpath pseudo devices by default for symmetrix and Clariion. This eliminates the need to use "powervxvm".
