Summary
The pdm command activates Predictive Data Migration (PDM). PDM replaces a
suspect physical drive, such as a drive with a PFA condition, with a different
drive. The replacement drive can be an unconfigured drive, a global spare, or a
dedicated spare to this disk array.
During PDM, the data on the suspect drive is transferred to the replacement drive
while the logical drive remains online.
After PDM, the replacement drive becomes part of the disk array. The suspect
drive become unconfigured and any PFA condition remains on it.
This command starts, stops, pauses, and resumes a PDM and monitors the
progress of a running PDM.
A PFA drive cannot be used until you clear the PFA condition. To clear the PFA
conditon of a physical drive, please refer to phydrv command on page 206.
