How To Protect Unprotected R1 While Maintaining RDF Relationship
Good afternoon,
We have an environment where replicate data as follows:
R5 STD -> Unprotected R1 --------> Unprotected R2 -> Protected GOLD
Our environment is DMX4 running 5773.176.
We are interested in protecting the currently unprotected R1's at the local site using either Raid 1 or Raid 5. The problem is that we don't want to dissolve the RDF relationhip. In other words, we don't want to have to reship several TB's of data.
Is this possible? EMC claims Mirror Position issues. We can't perform a convert due to the RDF relationship.
Thoughts? They would be greatly appreciated!
Thanks in advance!

Please verify your environment whether its running the SRDF over SRDF/AR – single hop?
Is the unprotected R1 allocated to any host?

TimeFinder/ Mirror would help you to create protection which runs in mirror emulation mode.

We are really not running SRDF/AR. We are running more of the SRDF Data Mobility (DM). We run an SYMMIR Establish between the STD and the R1 followed by an SYMRDF Establish between the R1 and R2 and finally a SYMMIR Establish between the R2 and GOLD.
The unprotected R1 is not allocated to any host.

Agreed that could move it to SYMCLONE instead of SYMMIR but it would force a full refresh. Right?

Yes, at very first time the clone device will be refreshed fully with the source device.

So you are suggesting that we SYMCLONE from the STD to the R1 instead of SYMMIR. This is a new relationship that will still need to be full shipped, right? Am I missing something? Remember, my goal is to not have to perform a full reship from the R1 to the R2.

Having to fully refresh the RDF relationship is what I am trying to avoid. It would take DAYS to get the data replicated again if we were forced to do so.
I am looking for a potential solution that will allow me to protect the currently unprotected R1 devices without having to reship the entire environment.
It is looking like this is not possible

Raid 5 Protected GOLD
Unprotected R1 Unprotected R2
Clone device… Only the clone device will be refreshed, not the R1 or any other device.
You can create a test environment to make sure the same.
