No you need to remove RDF protection before expanding metavolumes on both sides. And when you expanded both metavolumes (you don't need to preserve data on R2 since you'll soon run a full establish) you can create RDF pair again.
Note that creating a new pair requires a full establish.

Using dyn_rdf
Steps:

1.Suspend the RDF link between R1 - R2 devices
2.set dev 0BAD attribute=no dyn_rdf;
3.extend R1
4.extend R2
5.set dev 0BAD attribute=dyn_rdf;
6.Resume RDF link between R1 - R2 devices

Does that about cover it?

ok,
Is this the correct syntax for removing RDF protection?

set dev 0BAD attribute=no dyn_rdf;

Are you using static or dynamic RDF ??
In case you have static RDF you have to "convert" your devices (use symconfigure to change protection of affected devices). In case you have dynamic RDF, you can use the "symrdf deletepair" command.
The command you pasted can be used to remove dyn_rdf attribute but requires you already broke existing dynamic pair between 0BAD and its remote device (I guess it's BEEF)

0. add new metamembers on both sides attribute=dyn_rdf (use symconfigure on both sides)
1. suspend RDF link between R1 - R2 devices (symrdf susp)
2. break RDF pair between R1 - R2 devices (symrdf deletepair)
3. extend R1 (use symconfigure and a BCV to protect data)
4. extend R2 (use symconfigure and forget about data)
5. create RDF pair between R1 and R2 (use symrdf createpair)
6. run a full establish from R1 to R2 devices.

ok,
before I add hypers to the existing meta I will need to change the device types from RAID-5 to RDF1+R-5 is that correct or is that done when the create pair is established?

RDF1+R-5 means STATIC RDF. You simply have to add attribute=dyn_rdf to new metamembers.

Sorry, I'm still unclear on this step:

0.add new metamembers on both sides attribute=dyn_rdf (use symconfigure on both sides)

The meta I want to expand is device type RDF1+R-5... the new hypers I want to add to this meta are RAID-5, but are r1 + r2 capable. Do I need to run a convert dev xxx to RDF1+R-5 on the hypers before I add them to the meta I want to extend?

Can you please post full output of "symdev -sid xxx show 0BAD" and "symrdf -sid xxx -dynamic list" ?? I can't understand if you are using dyn_rdf or static RDF.

Ok your pair is a dynamic pair. Thus you don't need to use symconfigure and convert between RAID5 and RDF1+R-5. You need to follow the steps I suggested above ..

Your metavolume is RAID1+R-5 becouse it's in a RDF pair. As soon as you issue "symrdf deletepair" (with appropriate options) you'll have a plain RAID5 device with dyn_rdf attribute enabled, thus you can add new members (if they already have dyn_rdf attribute as I suggested in step 0) and when you have a bigger metavolume on both sides you can issue a "symrdf createpair" to have your RDF1+R-5 device.

Ok, that makes sense....
thanks so much for the help.... I wasn't involved with the setup so trying to get up to speed...

-thanks again
