IMPORTANT: If an error occurred in any HDD in 
logical drive while the PDM feature is being enabled, the 
data is copied onto the spare drive automatically. 
Consequently, the slot location initially assigned for a 
physical drive configuring logical drives may be changed. 
Consideration must be taken into account to use the PDM 
feature. See "3.11 PDM" for details.

If you click the center of the Background Activities tab, the BGA being run in the selected disk

executable at the RAID level (including expansion, rebuild, PDM and transition) to be displayed. 
See the section describing each BGA for details.
