At a recent DR exercise, we were able to gain access to another customer's
data on some of the DASD volumes that were allocated to us for the recovery.
This prompted us to look in greater detail at the informal agreement for data
erasure that we had in place with the DR Provider.
On investigation, we found that the old agreement was based on the use of
DASD technology that had since become obsolete following the installation
of a newer DASD subsystem at the DR site. Clearly, we now have to accept and
take on-board the full responsibility for the secure erasure of our data at the
conclusion of each DR exercise.
Initially, we tested and timed the secure volume erase facility of ICKDSF, but
our tests indicated that it would take in excess of 24 hours to erase all the DASD
volumes allocated to us at the DR site. This would have a huge impact on our 96
hour DR Exercise window.
In the end, we opted for Innovation's FDRERASE. Our tests have indicated that
it is significantly faster (yet still as secure) as the alternatives, and it
does not require an IPL in order to operate, further reducing any impact on the
96 hour DR Exercise window.
