Thank you Chris. Problem is solved. Should I flash the firmware as precaution? Still puzzled why initial procedure  in VD Mgmt tab did not work. All drives reset to Ready state in PD tab. -Dave
Dell Poweredge 2950 III with service tag <Admin note: Service tag removed as per TOU> received drives swapped from a near identical poweredge disposed. In the PERC 6i config utility the Controller 0, Disk Groups show as foreign. Following prior posts the procedure to import configuration, then delete was not effective. The prior configuration still appears in the menu. I desire to simply clear away all the VD configurations from the drives and controller. After these are cleared then next step will be to setup a configuration I desire. My new configuration is not relevant to this post. The purpose and only question is how to clear existing configurations from swapped drives. VD0 to clear off is 2 SAS PD/HDDs set as single virtual disk. Raid level 0, status is offline, SMART status =no error, VD count =1, PD count =2, operation = none VD1 is similar to VD0 other drive bays are currently empty.  For initial troubleshooting I have removed all HDD except a single disk in the server. This single disk also shows as foreign.  In PERC 6i config utility: VD MGMT shows CONTROLLER0 --no configuration present. F2 choices are  Config | Foreign Config as available. (Create New VD and Manage Preserved Cache are greyed out) Right pane of screen indicates "Foreign Config Present, Controller Prop.: DG count =0, VD count =0, PD count =1" PD MGMT shows only the single 139K-Mb SAS formatted, state =Foreign, SMART status =no error, Operation =none FOREIGN VIEW shows DG0 = foreign, Virtual disk 255 with DG count = 1. VD count =1, PD count =1  I have installed 3 of the disks individually in rotation as the sole HDD with similar results. WITH 2 SAS HDD installed only difference is VD Mgmt indicates DG count =0, VD count =0, PD count =2.   Foreign View indicates VD255 prop.: Raid =0, Raid Status = foreign, Size =na, Operation =none. | Disk Group Prop.: VD Count =1, PD Count =2, Ded HS =0 (since none exists).    
Unable to delete foreign HDD configuration, PERC 6i with used SAS disks.
