I want to change the normal devices to the RDF capable but the device is having data in it . Is it possible whether i can go ahead and change the attributes on the fly or i have to take the downtime and then i have to change it
if i take the downtime for it . what happens to the existing data ??
Device is from VMAX VMAX20K and running with 5876 engunity code
The attributes dyn_rdf, dyn_rdf1, dyn_rdf2 can be assigned to a device after device creation.
Create a command file containing the following syntax:
set device SymDevName attribute=device_attr;
Where SymDevName is the name of the Symmetrix device being altered and device_attr is the attribute being assigned to the device.
Possible values for device_attr are:
Unless this is on a VMax 10K. For the RDF attribute to be changed will require a BIN file update. With SRDF/DRDF enabled on a VMax 10K, all new devices get the attribute.
