Convert concatenated R1 meta to striped while replication is active

Question

Can anyone advise if a concatenated R1 meta can be converted to a striped meta while it is synchronously replicating to its R2 counterpart? If not, can you enumerate the steps for this type of conversion? This task involves 2 x Vmax boxes, both running 5875 code. Thanks.

No, you cannot convert a concatenated RDF meta into a striped meta directly. You cannot modify the meta configuration of a device while there is an SRDF relationship present.

So in order to do this, you would need to do the following:

Deletepair to remove the SRDF relationship
Convert the meta on both the R1 and R2 sides to striped (ensure you use the PROTECT_DATA=TRUE option on the R1 side)
Createpair to re-establish the SRDF relationship

Unfortuantely this will require a full sync from R1 > R2...but because of this, you really don't need to use a BCV and the PROTECT_DATA option on the R2 side since it'll be fully re-established with the R1.

Hope this helps.
