clear data on PE2950 disks

Have several PE2950 servers.  Need to wipe data on all disks.  The PE2850 RAID controller had an option to clear data from physical disks.  PE2950 PERC 6/i does not have this option, only clear data from foreign disks.

Will initiliazing a VD do the same thing as clearing a disk of its data?
