Isracard Group devises a novel way to verify
its system integrity before disaster occurs
By Jim Utsler { Photography by David Vaaknin

ost mainframe users
conduct disaster recovery
(DR) backups of some
sort. Many do so within a
machine-to-machine framework
with, for example, a production
system being supported by
a mirrored off-site box-or a
dedicated LPAR on a remote box.
That's fine if everything is
running well on the production
system, but if something is amiss,
such as a logical error, it will
roll over to the backup system.
When that system is needed in
the event of an emergency, it may
not function as intended and that
replicated error will muck up the
works if it's not discovered in time.
This happened several years ago
to a bank in Israel. When it rolled
over to its backup box, a logical
error that had been replicated to
the DR site caused a glitch that

M

kept both the primary and the
backup boxes out of service for a
number of nail-biting hours.
This cautionary tale wasn't
lost on Isracard Group. In fact,
Isracard's management urged the
company's IT team to develop a
backup-verification system that
would help it avoid a similar
DR failure. Now, in addition to
conducting common synchronous
replication, Isracard also uses
the space efficient FlashCopy*
technology (FlashCopy SE), an
IBM System Storage* DS8000*
function, to copy its production
data every business day and
conduct an IPL against it. If that
copy loads as expected and no
corrupted files are found, Isracard
can be assured that if an IPL is
required at the primary site, it will
succeed and its synchronous copy
is sound. If an issue does arise in

the verification process, it's then
quickly found and rectified in the
live DR environment.
As a result of this clever
backup-confirmation workaround, Mike Shorkend, Isracard's manager of central infrastructures, was dubbed by some
of his peers at a recent SHARE
conference as "The Guy Who
Does a DR Test Every Day."
"It's a fun label," he says, "but
that's in fact what we do-run a
DR test every day."
