Summary
This command allows the user to start, stop, pause or resume a PDM. PDM (Predictive Data Migration) is an
operation to replace an drive in the pool, which has a PFA condition, with a destination physical drive. The
destination physical drive can be an unconfigured drive, a global spare, or a dedicated spare to this pool.
During PDM, the data on the PFA drive will be transferred to the destination drive while the IO remains going
on. After PDM, the destination drive becomes part of the pool; the PFA drive will become unconfigured and PFA
condition will remain on. The PFA drive cannot be used for further configuration until the PFA condition is cleared
by the user. To clear the PFA condition of a physical drive, please refer to phydrv command with option -a clear.
