Data erasure ...
I noticed the new release notes on Powerlink for the new 5772 Enginuity code.
One of the good features is the Certified Data Erasure. However, if you think about it, if you don't have this code, every time a disk is replaced, your data is walking out the door. If the disks that are just marginal and get recycled then could your data end up in someone else's storage array? Are there plans to roll this out to the other Symmetrix lines?

I'm sure this holds true for all vendors, I've never heard of an incident where someone has inadvertantly had access to someone elses data through a spare replacement.
There is no plan to "back engineer" this feature into previous codes.

Let¿s say I have the new 5772 Enginuity code. How do I know the erase process has bean done on the disk?

Certified comes from being 'D.O.D. compliant' (Department of Defense). The program over-writes random bit patterns to ensure erasure of original data.
From Powerlink if you do a search for 'data erasure', it will present multiple documents for your review.
I hope this helps.

Anyway, besides spraying the disks with bits, is there any verification or notification that the customers get after this is done? Or is it just assumed to be done?

I sincerely apologize for the link issue. My mistake.
I will leave it up to each individual to do their own search via Powerlink on the subject.
The application has prompts and notifications. Such as the option to choose the number of Media Eraser 'wipes' (3x times, 5x times or 7x times). Notifications of estimate running time, progress and job completion.

I also just wanted to clarify that the "EMC Certified Data Erasure Services" for disks feature (to be released with Enginuity 5772 and as detailed by sysmgr) is a NEW feature to ensure the full data erasure of a single defective drive before it is removed from site.
This is an enhancement to the current "EMC Certified Data Erasure Services" feature available for Enginuity 5x67 to 5771. The current service is for a FULL box data erasure of all installed drives (to DOD standards, multiple passes, selectable data patterns, etc).
Again this is a full box erasure that can be performed by your local EMC Customer Engineer and this is typically requested before a Symmetrix is "traded in" (returned to EMC) OR re-deployed for other uses onsite....
Best Regards,
Michael.

My last posting was simply to clarify that this thread was discussing a different feature to the full box erasure service that is currently available (as detailed by Mr. TS2). The choice of the data erasure method (to DOD standards), the number of passes, etc, are certainly all questions to be answered when performing the full box certified data erasure.
I am afraid that Enginuity 5772 has not been GA'ed yet so I don't have the details on how a certified erasure at the disk level would be logged or reported. Perhaps some other EMC'ers know how this dialogue would apply to the new 5772 feature?......
Yes, from the information I have seen (which is obviously "Subject to change without notice", etc) the certified data erasure prior to a drive replacement at Enginuity 5772 appears to be an optional behaviour that needs to be licensed and it is an alternative to customers that currently have maintenance agreements where they physically retain all failed drives (for total data security).
I would suggest that anyone specifically interested in this new feature should speak to their friendly local EMC Sales Team - to see if it applies to their environment and addresses any current concerns with data security......
Thanks & Best Regards,
Michael.

EMC provides customers with a certificate of data erasure service completion and a report. The report shows details of which specific drives were involved and what level of data erasure was applied.
Solution Enabler SYMAUDIT commands are available to retrieve information on erase cycles. These commands can also be used by customers.
I hope this helps.

Wolfgang
