srdf failover

Hi All,

How can i failback a server which is failedover a long back.The problem is there are some devices allocated(while group is in failed over state) to this server(DR) those are not part of SRDF so now i have to create same size devices on the primary side and replicate data from R2 to R1(update until some tracks) and failback).Can we add the devices to device group in failedover state.Can someone give me the steps to do this.

Thanks

    Bullop, Its running in failedover state that means no replication back to R1(links down and r2 is up).All i need to do is make r1 up and running.

    Thanks

    Hello Praveen,

    I think at this point you should call into the support center for assistance. I would not want to tell you the wrong

    thing to do.I wouldn't want to have you do anything that would have you lose any data. Sorry.

    Praveen was Support able to assist with this.

    From what I have read I believe the cleanest way to have done this is as per below, however as per the last comment I would recommend you consult support before performing any of these actions

    1. Do a swap , so this makes the R2 (Target)  the R1 (Source) and the R1 (Source)  the R2 (Target)

    2. You can then add your 2 devices at this stage

    3. Allow Devices to Synchronize

    4. Perform a Failover

    5. Do a Swap, returns back to your previous state, except now you have the 2 devices added, and the data from the orignal R2 is now on the original R1

    Hi, I already opened a case with emc as a low priority so still in the queue.Anyways what will be the replication mode if we perform a swap operation.

    Thanks
