Re: Clear data on V3700 log files

I need to clear the data on multiple V3700 units, (since replaced by Flash)
and show the log files that report the data wipe. I cannot find anything
on Google or other search engines that do not go out of their way to keep
the data. I can remove the volumes but I have to prove they are wiped.

Suggestions?

Once attached to a dedicated partition (just for operations safety), using SST, you can try to initiliaze and format them through SST

task #8 in https://www.ibm.com/docs/en/i/7.5?topic=checklist-secure-data-erase-i

I don't know if there is a specific entry in system logs. In the past, when I wrote a procedure for such a need, I was using screenshots showing the volume serial numbers before the initialize operations, and a couple of other screenshots at the beginning of the operation, and immediately after. This was to prove that the proper disks were initialized, and therefore wiped.

Our procedure was based to https://www.ibm.com/support/pages/initialize-disk-drives-so-all-data-erased-system document (they write "Configure all the disk drives by adding them into system ASP (ASP 1). This writes zeroes on the disk drives so that only the LIC is loaded.").

FYI, I remember an old RPQ (https://www.ibm.com/common/ssi/ShowDoc.wss?docURL=/common/ssi/rep_rp/3/ENUSP84513/index.html) which was available several years ago and was able to write zeros on unconfigured disks. But never used.
