The array probably has to go back to EMC, especially if the DMX-4 was replaced by newer EMC equipment or superseded by another Vendor.
You can also hire one of the software vendors who can come out and zero-wipe the drives. Not cheap, but a heck of a lot cheaper than shredding drives.

unless array needs to go back to EMC (highly doubt) it's cheaper to shred the drives using authorized data destruction company.

.20 cents per pound to shred drives, trust me much cheaper than 10k secure erasure engagement.

EMC doesn't publish the process to run the Data Erasure script. it's a pay-for service from EMC or its authorized service partners. If you want the process performed on your array, you'll have to pay for it.
Otherwise, your best bet is to destroy all the LUNs, create new LUNs and erase them with a freeware tool, such as DBAN. Is it as good as a certified erasure? No way. But if you're not paying EMC to do it, this is probably the best you can achieve.
Let us know if that helps!

I typically create new LUNs, just to attempt to change the array configuration in any way possible. If you choose to re-write data on the already-allocated LUNs, there is always a greater chance to forensically reproduce the data that was once on the LUN. Is this a very large chance? No, but in the absence of actual encryption on the drive, there's always a chance that some cleartext data could be reproduced.
Destroying the data with a software tool is always dicey, but it's the best chance you've got.
