Not sure about the JBOD question in relation to re-using the system after sanitation.
Alternatively, look into deleting your spares then thick provision out the entire 3PAR available capacity (super large R1 with a set size of 4 or whatever is max), this will writes 0s over the entire space... then if you require higher sanitation standards... you could allocate those LUNs to a host and use which ever secure erase tools against the luns that you prefer. Might even suggest over provisioning the unit and running secure erase until IO operations halt do to no free space left.
