Failover excercise

Hi,

We're planning for failover test , will discard data change at R2 side after completion of DR drill.

Can we use the following commands?

symrdf -g grp failover ; Begin failover

symrdf -g grp establish ; to enable production after test

Thanks.

If you want to discard the changes at R2 then just do split. After DR test run establish, during DR test PROD will be available if you choose to do split. If you will do failover your PROD will go WD and DR become RW enable for local servers.

I do not think you will be able to run establish in failedover state.

Majid,

Thanks for the reply.

We don't want prod to be available during dr test.

Are you saying I have both options - failover & split would work? Can I do just establish to discard data at r2?

Thanks.

By fail over R1 become WD (prod down)and R2 become RW. By split u cna get R2 RW at the same R1/PROD still available.

Probably you can RW enable R1 devices, WD R2 devices and issue an establish.
A few more commands, but addresses the issue

Was this ever answered I'm looking at a similar plan that has been created by somebody else.

I've never used Establish after a Failover before.

EMC Solution Enabler Symmetrix SRDF Family CLI Version 7.3 Product Guide states that a control option Establish is valid against FailedOver device with the caveat that e. Source is not visible to any host.

Does anybody have any experience running this?

The establish should copy the data from the R1 to the R2 and putting the source and target devices back to the pre-test state and discarding any changes made to the R2 whilst it was failed over.
