ESS Shark and Disaster Recovery through PPRC

ESS Shark and Disaster Recovery through PPRC
hello list,

those of you who have Shark DASD (ESS)... AND who use a PPRC technique for
their Disaster Recovery strategies.... how do you do this? do you have the
double Sharks or wot?

to make my question clear I'll have to explain things a bit:

I am working at a new client's and since it's a big outsourcing biz,
relatively new in taking over, we are still trying to customise all the
different DR scenarios... during a meeting today we discussed using the ESS
we have, basically somebody heard from reliable sources :-) that Shark
could greatly improve our performance (yeah so what's new) and since I had
been told that our data currently resided on Shark I just decided to make
sure and asked our SMS people.

it turns out that our Shark is only used by our Training System, lucky so
and so's, because of all problems relating to this PPRC - and the SMS
people say that this is as is and also as will be since it is impossible to
implement PPRC on different device types and obviously Shark's are not
included in the x-mas sales at the local supermarket...

they are probably absolutely right, just thought I'd ask what you guys had
found as a solution if you had met this problem.

TIA, happy festive season to you all and ciao!

Can now be downloaded as a PDF file and ordered in hardcopy two weeks
following the Publish Date! (see

This is very readable and also includes an excellent appendix discussing

and FlashCopy.
